T1600 Router Description
The T1600 Core Router is a complete routing system that provides Gigabit Ethernet, SONET/SDH, and other high-speed interfaces for large networks and network applications, such as those supported by Internet service providers (ISPs). The T1600 router accommodates up to eight Flexible PIC Concentrators (FPCs), each of which can be configured with a variety of network media types. The router provides up to 800 gigabits per second (Gbps), full duplex (1600 Gbps of any-to-any, nonblocking, half-duplex) switching.
The router architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the router to achieve high performance.
- Control operations in the router are performed by the host subsystem, which runs Junos operating system (Junos OS) to handle routing protocols, traffic engineering, policy, policing, monitoring, and configuration management.
- Forwarding operations in the router are performed by the Packet Forwarding Engines, which consist of hardware, including ASICs, designed by Juniper Networks.
Application-specific integrated circuits (ASICs) are a definitive part of the router design; they enable the router to achieve data forwarding rates that match current fiber-optic capacity. The T1600 router provides up to a total of 1600 million packets per second (Mpps) of forwarding.

T1600 Component Redundancy
The T1600 Core Router is designed so that no single point of failure can cause the entire system to fail. The following major hardware components are redundant:
- Switch Interface Boards (SIBs)—The T1600 router has five SIBs.
See "T1600 Switch Interface Board (SIB) Description" on page 119.
- Host subsystem—The host subsystem consists of a Routing Engine functioning together with a control board. The router can have one or two host subsystems. If two host subsystems are installed, one functions as the master and the other functions as the
backup. If the master host subsystem (or either of its components) fails, the backup can take over as the master. To operate, each host subsystem requires a Routing Engine installed in an adjacent slot to a control board.
If the Routing Engines are configured for nonstop active routing, the backup Routing Engine automatically synchronizes its configuration and state with the master Routing Engine. Any update to the master Routing Engine state is replicated on the backup Routing Engine. If the backup Routing Engine assumes mastership, packet forwarding continues through the router without interruption. For more information about nonstop active routing, see the Junos OS High Availability Library for Routing Devices.

NOTE: Nonstop active routing is supported for standalone T1600 routers in Junos OS Release 8.5 and later. Nonstop active routing is supported for T1600 routers in a routing matrix in Junos OS Release 10.0 and later.
See "T1600 Host Subsystem Description" on page 41
- SONET Clock Generators (SCGs)—The router has a standard configuration of one SCG. A second can be purchased to function as backup. If one SCG fails, the other becomes the master SCG. Mastership of the SCGs is independent of the host subsystem, so routing functions are not affected.
See "T1600 SONET Clock Generators Description" on page 28.
- Power supplies—The router has two power supplies, which share the load evenly. If one power supply fails, the other power supply can provide full power to the router indefinitely.
See "T1600 Power System Description" on page 105.
- Cooling system—The cooling system has redundant components, which are controlled by the host subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router indefinitely.
See "T1600 Cooling System Description" on page 37.

System Architecture Description for T Series Routers
The T Series Core Routers have two main architectural components:
- Routing Engine—One or more Routing Engines provide Layer 3 routing services and network management.
- Packet Forwarding Engines—These high-performance, ASIC-based components provide Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding.
The Routing Engines and the Packet Forwarding Engines perform their primary tasks independently, although they constantly communicate through multiple 100 millions of packets per second (Mbps) links. This arrangement streamlines forwarding and routing control and runs Internet-scale backbone networks at high speeds. Figure 3 on page 7 shows the relationship between the Routing Engine and the Packet Forwarding Engines.

•Packet Forwarding Engine Architecture for T Series Routers on page 8
Routing Engine Functions for T Series Routers
The Routing Engine handles all routing protocol processes, as well as the software processes that control the router's interfaces, the chassis components, system management, and user access to the router. The routing and software processes run on top of a kernel that interacts with the Packet Forwarding Engine.
The Routing Engine constructs and maintains one or more routing tables (see Figure 4 on page 7). From the routing tables, the Routing Engine derives a table of active routes, called the forwarding table, which is then copied into the Packet Forwarding Engine. The design of the ASICs allow the forwarding table in the Packet Forwarding Engine to be updated without interrupting forwarding performance.

The Routing Engine includes the following functions and features:
- Processing of routing protocol packets—The Routing Engine handles all packets that concern routing protocols, freeing the Packet Forwarding Engine to handle only packets that represent Internet traffic.
- Software modularity—Because each software process is devoted to a different function and uses a separate process space, the failure of one process has little or no effect on the others.
- In-depth Internet functionality—Each routing protocol is implemented with a complete set of Internet features and provides full flexibility for advertising, filtering, and modifying routes. Routing policies are set according to route parameters (for example, prefix, prefix lengths, and BGP attributes).
- Scalability—Junos OS routing tables have been designed to hold all the routes in current networks with ample capacity for expansion. Additionally, Junos OS can efficiently support large numbers of interfaces and virtual circuits.
- Management interface—Different levels of system management tools are provided, including the Junos OS command-line interface (CLI), the Junos XML management protocol, the craft interface, and SNMP.
- Storage and change management—Configuration files, system images, and microcode can be held and maintained in primary and secondary storage systems, permitting local or remote upgrades.
- Monitoring efficiency and flexibility—The router supports functions such as alarm handling and packet counting on every port, without degrading packet-forwarding performance.

Packet Forwarding Engine Architecture for T Series Routers
The Packet Forwarding Engines provide the Layer 2 and Layer 3 packet switching, forwarding, and route lookup functions. The Packet Forwarding Engines are implemented in ASICs that are physically located on the FPCs and the PICs. To ensure the efficient movement of data, the router is designed so that ASICs on the hardware components handle the forwarding of data.
- Packet Forwarding Engine Components on page 9
• Data Flow on page 9
Packet Forwarding Engine Components
Each Packet Forwarding Engine consists of the following components:
- Layer 2/Layer 3 Packet Processing ASIC, which performs Layer 2 and Layer 3 encapsulation and decapsulation, and manages the division and reassembly of packets within the router.
- Queuing and Memory Interface ASICs, which manage the buffering of data cells in memory and the queueing of notifications.
• T Series Internet Processor, which provides the route lookup function. - Switch Interface ASICs, which extract the route lookup key and manage the flow of data cells across the switch fabric.
Media-specific ASICs on the PICs perform control functions tailored to the PIC media types.
Data Flow
To ensure the efficient movement of data, the router is designed so that ASICs on the hardware components handle the forwarding of data. Data flows through the router in the following sequence (see Figure 5 on page 9):

- Packets arrive at an incoming PIC interface.
- The PIC passes the packets to the FPC, where the Layer 2/Layer 3 Packet Processing ASIC performs Layer 2 and Layer 3 parsing and divides the packets into 64-byte cells.
- The Switch Interface ASIC extracts the route lookup key, places it in a notification, and passes the notification to the T Series Internet Processor. The Switch Interface ASIC also passes the data cells to the Queuing and Memory Interface ASICs for buffering.
- The Queuing and Memory Interface ASICs pass the data cells to memory for buffering.
- The T Series Internet Processor performs the route lookup and forwards the notification to the Queuing and Memory Interface ASIC.
- The Queuing and Memory Interface ASIC sends the notification to the Switch Interface ASIC facing the switch fabric, unless the destination is on the same Packet Forwarding Engine. In this case, the notification is sent back to the Switch Interface ASIC facing the outgoing ports, and the packets are sent to the outgoing port without passing through the switch fabric (see Step 13).
- The Switch Interface ASIC sends bandwidth requests through the switch fabric to the destination port. The Switch Interface ASIC also issues read requests to the Queuing and Memory Interface ASIC to begin reading data cells out of memory.
- The destination Switch Interface ASIC sends bandwidth grants through the switch fabric to the originating Switch Interface ASIC.
- On receipt of each bandwidth grant, the originating Switch Interface ASIC sends a cell through the switch fabric to the destination Packet Forwarding Engine.
- The destination Switch Interface ASIC receives cells from the switch fabric. It extracts the route lookup key from each cell, places it in a notification, and forwards the notification to the T Series Internet Processor.
- The T Series Internet Processor performs the route lookup, and forwards the notification to the Queuing and Memory Interface ASIC.
- The Queuing and Memory Interface ASIC forwards the notification, including next-hop information, to the Switch Interface ASIC.
- The Switch Interface ASIC sends read requests to the Queuing and Memory Interface ASIC to read the data cells out of memory, and passes the cells to the Layer 2/Layer 3 Packet Processing ASIC.
- The Layer 2/Layer 3 Packet Processing ASIC reassembles the data cells into packets, adds Layer 2 encapsulation, and sends the packets to the outgoing PIC interface.
- The outgoing PIC sends the packets out into the network.

Outstanding Issues with the T1600 Router
This topic lists outstanding hardware issues with the T1600 Core Router.
- To support the 10-Gigabit Ethernet LAN/WAN PIC with Oversubscription and SFP+ (model number PD-5-10XGE-SFPP) in the T1600-FPC4-ES (part number 710-013037), REV 13 and later is required.
T1600-FPC4-ES (part number 710-013037), REV 12 and earlier does not support the 10-Gigabit Ethernet LAN/WAN PIC with Oversubscription and SFP+ (model number PD-5-10XGE-SFPP).
- When the C8000-RE Routing Engine is installed, the LEDs for the ETHERNET ports on the connector interface panel (CIP) have the following issues:
- Model number RE-DUO-C1800-8G (part number 740-026941 Rev 7)—The activity LEDs, labeled ACT0 and ACT1, for the ETHERNET ports on the connector interface panel (CIP) are always steadily green, even when no cables are connected to the ports.
For RE-DUO-C1800-8G (part number 740-026941 Rev 8) and above, the CIP LED behavior is as described in the T1600 Core Router Hardware Guide.
- Model numbers RE-DUO-C1800-8G and RE-DUO-C1800-16G—The LEDs labeled GRN = 100M and YEL = 10M is always yellow, but the speed is always a 100-Mbps connection.
- After powering on or off a power supply, wait at least 60 seconds before turning it back off or on again.
- After a power supply is powered on, it can take up to 60 seconds for status indicators—such as LEDs on the power supply, show chassis commands, and messages on the craft interface LCD—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
- The external clock inputs on the SONET Clock Generators (SCGs) with DB-9 ports (model number SCG-T) are not supported.
- The external clock inputs on the SONET Clock Generators (SCGs) with RJ-45 ports (model number SCG-T-EC) are supported for JUNOS OS Release 10.4 and later.
For complete information about the router, see the T1600 Core Router Hardware Guide. For information about software issues, see the Junos OS Release Notes.

Errata with the T1600 Router Documentation on page 12.
Errata with the T1600 Router Documentation
- The name of the T1600 Core Router PIC Guide has changed to T1600 Core Router Interface Module Reference. Some documentation references still refer to the T1600 Core Router PIC Guide.
- The verifying operation procedure in the T1600 Router Upgrade Guide incorrectly lists CB 0 REV 06 710-007655 KB9648 Control Board (CB-T) in the output.

NOTE: The control board shown as CB-T in the CLI output is the T640 standard control board (model number CB-L-T), which is not supported for T1600 routers, and is not the T-series control board (model number CB-T).

T1600 Chassis Description
The T1600 Core Router chassis is a rigid sheet metal structure that houses all the other T1600 router components (see Figure 6 on page 20 and Figure 7 on page 21). The chassis measures 37.45 in. (95.1 cm) high, 31 in. (78.7 cm) deep, and 17.43 in. (44.3 cm) wide. The chassis can be installed into many types of racks or cabinets.
The chassis includes the following features (see Figure 6 on page 20 and Figure 7 on page 21):
- Front-mounting flanges for mounting in a four-post rack or cabinet or front-mounting in an open-frame rack.
- Center-mounting metal brackets for center-mounting in an open-frame rack.
- Handles on each side to facilitate positioning the router in the rack. Do not use the handles to lift the router.
- Two electrostatic discharge (ESD) points (banana plug receptacles), one front and one rear.

CAUTION: Before removing or installing components of a router, attach an ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router.

WARNING: The router must be connected to earth ground during normal operation.

T1600 Midplane Description
The midplane is located in the center of the chassis and forms the rear of the FPC card cage (see Figure 8 on page 22). The FPCs install into the midplane from the front of the chassis, and the SIBs, Routing Engines, and control boards and SCGs install into the
midplane from the rear of the chassis. The power supplies and cooling system components also connect to the midplane.
The midplane performs the following major functions:
- Data path—Data packets are transferred across the midplane from the Packet Forwarding Engine on the originating FPC to the SIBs, and from the SIBs across the midplane to the Packet Forwarding Engine on the destination FPC.
See "Packet Forwarding Engine Architecture for T Series Routers" on page 8.
- Power distribution—The router power supplies are connected to the midplane, which distributes power to all the router components.
See "T1600 Power System Description" on page 105.
- Signal path—The midplane provides the signal path to the FPCs, SIBs, Routing Engines, CB, and other system components for monitoring and control of the system.

T1600 Front Cable Management System Description
The front cable management system (see Figure 9 on page 23) consists of a row of nine semicircular plastic bobbins mounted on the front of the router below the FPC card cage. The PIC cables pass between the bobbins and into the tray, keeping the cables organized and securely in place. The curvature of the bobbins also helps maintain the proper bend radius for optical PIC cables.
You can pull the front cable management system up and outward to lock it into the maintenance position. This allows you to access the lower fan tray and the front air filter.

T1600 Chassis Description on page 19. •T1600 Rear Cable Management System Description on page 23
T1600 Rear Cable Management System Description

NOTE: The rear cable management system is not needed for standalone T1600 routers with T1600-SIBs and T-CBs.
For T1600 routers connected to a TX Matrix Plus router, you can use the optional rear cable management system to organize, support, and provide strain relief for the cables connected to the TXP-T1600 or TXP-LCC-3D SIBs, and the cables connected to the LCC-CBs. The rear cable management system consists of one cable management arm. The cables are routed to the left side of the T1600 router, and then toward the top of the chassis, where you can route the cables to the TX Matrix Plus router. The cable management system adds 9.5 in. (24.1 cm) to the depth of the T1600 chassis, and 2.4 in. (6.2 cm) to the left side of the chassis.
- The optional rear cable management system (model number CBL-MGR-TXP-LCC) supports the TXP-T1600 configuration and fiber-optic array cables only (see Figure 10 on page 24).
- The LCC rear cable management system (model number CBL-MGR-TXP-3D-LCC) can be used for any configuration including TXP-T1600 configuration, TXP-T1600-3D configuration, TXP-T4000-3D configuration, and TXP-Mixed-LCC-3D configuration.
See the TX Matrix Plus Router Hardware Guide for instructions on installing and using the T1600 rear cable management system.

T1600 Connector Interface Panel (CIP) Description
• T1600 Connector Interface Panel (CIP) Components on page 25
• Management Ports on page 26
• T1600 Alarm Relay Contacts on page 27
T1600 Connector Interface Panel (CIP) Components
The Connector Interface Panel (CIP) consists of Ethernet, console, and auxiliary ports for the Routing Engines and alarm relay contacts (see Figure 11 on page 26).
Figure 11: CIP

The CIP is located at the left side of the FPC card cage, above the front electrostatic discharge point. The CIP is hot-pluggable.
Management Ports
The CIP has two sets of management ports (see Figure 11 on page 26) that you use to connect the Routing Engines to external management devices. The upper set of ports, labeled HOST 0, connects to the Routing Engine in slot RE0; and the lower set, labeled HOST 1, connects to the Routing Engine in slot RE1. From these management devices, you can use the CLI to configure the router.
Each set includes the following ports:
- ETHERNET—Connects the Routing Engine through an Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management. The port uses an autosensing RJ-45 connector to support both 10- and 100-Mbps connections.
- One small LED on the upper left edge of the ETHERNET port, labeled ACT, indicates whether traffic is passing through the port.
- One small LED on the lower left edge of the ETHERNET port indicates the connection in use: the yellow LED lights for a 10-Mbps connection, and the green LED lights for a 100-Mbps connection.

NOTE: When an RE-C18000 is installed, the connection LED is always yellow for both a 10-Mbps connection and 100-Mbps connection.
- CONSOLE—Connects the Routing Engine to a system console through an RS-232 (EIA-232) serial cable.
- AUXILIARY—Connects the Routing Engine to a laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.
T1600 Alarm Relay Contacts
The CIP has two alarm relay contacts for connecting the router to external alarm devices (see Figure 11 on page 26). Whenever a system condition triggers either the red or yellow alarm on the craft interface, the alarm relay contacts are also activated. The alarm relay contacts are located below the Routing Engine ports. The terminal blocks that plug into the alarm relay contacts are supplied with the router. They accept wire of any gauge between 28-AWG and 14-AWG (0.08 and 2.08), which is not provided. Use the gauge of wire appropriate for the external device you are connecting.

T1600 Craft Interface LCD and Navigation Buttons
A four-line LCD is located in the craft interface, along with six navigation buttons. The LCD operates in two modes:
- LED idle mode
- LED alarm mode
During normal operation, the LCD operates in idle mode and reports current status information, as shown in Figure 16 on page 32.
Figure 16: LCD in Idle Mode

The lines in the display report the following information:
- First line—Router name.
- Second line—Length of time the router has been running, reported in the following form:
Up days + hours:minutes
- Third and fourth lines—Status messages, which rotate at 2-second intervals. Some conditions, such as removal or insertion of a system component, can interrupt the messages.
To add a message that alternates every 2 seconds with the default status messages, use the set chassis display message command. For more information, see set chassis display message.
When a red or yellow alarm occurs, the LCD switches to alarm mode and reports the alarm condition, as shown in Figure 17 on page 33.
Figure 17: LCD in Alarm Mode

The lines in the display report the following information:
- First line—Router name.
• Second line—Number of active alarms. - Third and fourth lines—Individual alarm messages, with the most severe condition shown first. The prefix on each line indicates whether the alarm is a red (R) or yellow (Y) alarm.

T1600 Craft Interface Alarm LEDs and ACO/LT Button
Two large alarm LEDs are located at the upper left of the craft interface. The circular red LED lights to indicate a critical condition that can result in a system shutdown. The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.
A condition that causes an LED to light also activates the corresponding alarm relay contact on the connector interface panel (CIP). The LCD on the craft interface reports the cause of the alarm.
To deactivate red and yellow alarms, press the button labeled ACO/LT (for "alarm cutoff/lamp test"), which is located to the right of the alarm LEDs. Deactivating an alarm turns off both LEDs and deactivates the device attached to the corresponding alarm relay contact on the CIP. However, the LCD continues to report the alarm message until you clear the condition that caused the alarm.

Cooling System Components and Descriptions
• T1600 Cooling System Description on page 37
T1600 Cooling System Description
The cooling system components work together to keep all router components within the acceptable temperature range. The host subsystem monitors the temperature of the router components. When the router is operating normally, the fans function at lower than full speed. If a fan fails or the ambient temperature rises above a threshold, the speed of the remaining fans is automatically adjusted to keep the temperature within the acceptable range. If the ambient maximum temperature specification is exceeded and the system cannot be adequately cooled, the Routing Engine shuts down some or all of the hardware components.

Figure 18 on page 38 shows the airflow through the router.
Figure 18: Airflow Through the Chassis

Fan Trays

NOTE: The standard fan trays and quiet fan trays are not interchangeable with each other. All fans in the chassis must be either standard fan trays or quiet fan trays.
The cooling system contains the following fan trays:
- One rear fan tray cools the components installed in the rear card cage (the Routing Engines, control boards, SCGs, and SIBs). The T1600 router supports the following rear fan trays:
- The standard rear fan tray, supported by Junos OS 8.5 and later, contains eight fans. It has no label and is not interchangeable with the standard front fan trays.

T1600 Host Subsystem Description
The host subsystem provides the routing and system management functions of the router. You can install one or two host subsystems on the router. The host subsystem consists of a Routing Engine and an adjacent control board. To operate, each host subsystem functions as a unit; the Routing Engine requires the corresponding control board, and vice versa.

NOTE: We recommend that you install two host subsystems for redundant protection. If you install only one host subsystem, we recommend that you install it in slots REO and CBO.
Each host subsystem has three LEDs, located on the upper right of the craft interface, that display its status. In addition, there are LEDs on each Routing Engine and control board.

•T1600 Control Boards Description on page 66
•T1600 Craft Interface Host Subsystem LEDs on page 34
T1600 Routing Engine Description
The Routing Engine runs Junos OS. Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the T1600 Core Router, control the T1600 router interfaces, control some chassis components, and provide the interface for system management and user access to the router.
You can install one or two Routing Engines in the router. The Routing Engines install into the upper rear of the chassis in the slots labeled RE0 and RE1. Each Routing Engine requires a control board to be installed in the adjacent slot. RE0 installs below CBO, and RE1 installs above CB1. A Routing Engine does not power up without a control board present in the adjacent slot.
If two Routing Engines are installed, one functions as the master and the other acts as the backup. If the master Routing Engine fails or is removed and the backup is configured appropriately, the backup takes over as the master. If the host system is redundant, the backup Routing Engine is hot-removable and hot-insertable, but the master Routing Engine is hot-pluggable. A Routing Engine that is not redundant requires that you power down the router before replacement.

NOTE: For specific information about Routing Engine components (for example, the amount of DRAM), issue the show chassis routing-engine command.
The ports for connecting the Routing Engine to external management devices are located on the Connector Interface Panel (CIP).

NOTE: If two Routing Engines are installed, they must both be the same hardware model, except during upgrade.
The T1600 router supports the Routing Engines listed in Table 11 on page 43

Figure 22: Routing Engine 600

Each Routing Engine 600 (shown in Figure 22 on page 43) consists of the following components:
- CPU—Runs Junos OS to maintain the router's routing tables and routing protocols. It has a Pentium-class processor.
- SDRAM—Provides storage for the routing and forwarding tables and for other Routing Engine processes.
- CompactFlash card—Provides primary storage for software images, configuration files, and microcode. The fixed CompactFlash card is inaccessible from outside the router.
- Hard disk—Provides secondary storage for log files, memory dumps, and rebooting the system if the CompactFlash card fails.
- EEPROM—Stores the serial number of the Routing Engine.
- Interfaces for out-of-band management access—Provide information about Routing Engine status to devices (console, laptop, or terminal server) connected to ports located on the Connector Interface Panel (CIP).

NOTE: The router's management Ethernet interface fxp0 is the interface for connecting network devices to the router through the ETHERNET port on the connector interface panel (CIP). Junos OS automatically creates fxp0, but you must configure its logical interface, fxp0.0, with a valid IP address before you can use fxp0 as a management port.
The faceplate of the Routing Engine 600 contains the following:
- One PC Card slot—Accepts a removable PC Card, which stores software images for system upgrades.
A slot labeled PC CARD on the Routing Engine faceplate accepts a Type I PC Card, as defined in the PC Card Standard published by the Personal Computer Memory Card International Association (PCMCIA). The TX Matrix router is shipped with a PC Card that contains Junos OS. The PC Card can be used to copy Junos OS from the PC Card onto the Routing Engine. You can also copy Junos OS from the Routing Engine onto a PC Card, for example, to create a backup copy of upgrade software that you have obtained from Juniper Networks. Instructions for copying software to a PC Card are available at the Juniper Networks Support Web site (http://www.juniper.net/support/);
after logging in, navigate to the Customer Support Center, then to the download page for Junos OS.

NOTE: The software on a PC Card is loaded only onto the Routing Engine into which the PC Card is inserted. It is not automatically copied to the other Routing Engine.

T1600 Control Boards Description
The T1600 chassis supports up to two control boards. The Routing Engine requires an adjacent control board to provide control and monitoring functions for the T1600 Core Router. These functions include determining Routing Engine mastership, controlling power and reset for the other T1600 router components, monitoring and controlling fan speed, and monitoring system status.
You can install up to two control boards in the chassis. Control boards install into the upper rear of the chassis in the slots labeled CB0 and CB1 (referred to as CB-0 and CB-1, top to bottom). If two control boards are installed, one functions as the master and the other as its backup. If the master fails or is removed, the backup restarts and becomes the master.
Each control board requires a Routing Engine to be installed in the adjacent slot. CBO installs above RE0, and CB1 installs below RE1. Control boards cannot function if a Routing Engine is not present in the adjacent slot.
If the host system is redundant, the backup control board is hot-removable and hot-insertable, but the master control board is hot-pluggable. A control board that is not redundant is hot-pluggable.
The T1600 router supports the control boards listed in Table 37 on page 67.

T1600 FPC Function
FPCs house the PICs that connect the T1600 Core Router to network media. The main function of an FPC is to connect the PICs installed in it to the other T1600 router components. The Packet Forwarding Engine receives incoming packets from the PICs installed on the FPC and forwards them through the switch planes to the appropriate destination port. In a maximum configuration with eight Type 4 FPCs installed, the Packet Forwarding Engines can forward up to 1600 million packets per second (Mpps) for all packet sizes. The T1600 Core Router provides up to 800 gigabits per second (Gbps), full duplex switching (1600 Gbps of any-to-any, nonblocking, half-duplex switching).
When you install an FPC into a functioning router, the Routing Engine downloads the FPC software, the FPC runs its diagnostics, and the PICs housed on the FPC, are enabled. Forwarding on other FPCs continues uninterrupted during this process.
T1600 FPC Slots
Up to eight FPCs install vertically in the front of the router. The FPC slots are numbered FPC0 through FPC7, left to right. If a slot is not occupied by an FPC, an FPC blank panel must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.
T1600 FPC Components
Each FPC consists of the following components:
- FPC card carrier.
- One or two Packet Forwarding Engines, consisting of Layer 2/Layer 3 Packet Processing ASICs, Switch Interface ASICs, T-series Internet Processor ASICs, and a Memory Mezzanine Board (MMB) which includes the Queuing and Memory Interface ASICs.
• Each Type 1 FPC has one Packet Forwarding Engine
• Each Type 2 FPC has one Packet Forwarding Engine
• Each Type 3 FPC has two Packet Forwarding Engines
• Each T640-FPC4-ES has one Packet Forwarding Engine
• Each T640-FPC4-1P-ES has one Packet Forwarding Engine
• Each T1600-FPC4-ES has two Packet Forwarding Engines - Processor Mezzanine Board (PMB), which includes a 300-MHz CPU, system controller, 256 MB of SDRAM, and two Fast Ethernet interfaces.
- Two LEDs, located on the craft interface above the FPC, that display the status of the FPC.
- FPC online/offline button, located on the craft interface above the FPC.
T1600 FPC Terminology
Regardless of whether you are holding an FPC vertically or horizontally, this document uses the same terms for all four edges of the FPC (see Figure 30 on page 75):
- Faceplate—Edge of the FPC that has slots into which you insert the PICs
- Connector edge—Edge opposite the faceplate; this edge has the connectors that attach to the midplane
- Top edge—Edge at the top of the FPC when it is vertical
- Bottom edge—Edge at the bottom of the FPC when it is vertical
Figure 30: FPC Edges

Identifying the T1600 FPCs
Check the label on the faceplate to identify the FPC. For FPCs without a label on the faceplate, check the location of a PIC's offline button and how the PIC is secured to the FPC. See Table 41 on page 75.

T1600 PIC Description
PICs provide the physical connection to various network media types, receiving incoming packets from the network and transmitting outgoing packets to the network. During this process, each PIC performs framing and line-speed signaling for its media type. Before transmitting outgoing data packets, the PICs encapsulate the packets received from the FPCs. Each PIC is equipped with an ASIC that performs control functions specific to the media type of that PIC.
PICs are hot-removable and hot-insertable. You can install up to four PICs in each Type 1, 2, and 3 FPC, one PIC in each T640 Enhanced Scaling FPC4 or Enhanced Scaling FPC4-IP, and one or two PICs in each T640 Enhanced Scaling FPC4. Type 1 and Type 2 PICs have captive screws at their upper and lower corners. Type 3 PICs have an upper ejector handle and a lower captive screw. Type 4 PICs have an upper ejector handle and a lower ejector handle.
The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, IP Services, and SONET/SDH interfaces. Blank PICs resemble other PICs but do not provide any physical connection or activity. When a slot is not occupied by a PIC, you must insert a blank PIC to fill the empty slot and ensure proper cooling of the system.

T1600 PIC Combination Limitations
In most cases, you can install PICs of different media types on the same FPC as long as the FPC and the router support those PICs. However, configuration rules might limit certain combinations of PICs on some platforms.
Newer Junos OS services for some PICs can require significant Internet Processor ASIC memory. Ethernet and SONET PICs typically do not use large amounts of memory. Gigabit Ethernet, ATM2, IQ serial PICs, and Multiservices PICs use more. To conserve memory, you can group PICs in the same family together on the same FPC.
If you have different PIC families on a single FPC, review the configuration rules to plan which PICs to install on the FPCs for your router. Consult technical bulletin PSN-2007-01-023 for information about configuration rules for PIC combinations on the Juniper Networks Support site at https://www.juniper.net/alerts/.
When you upgrade to Junos OS Release 7.5 or later, a warning appears if any configuration rules affect your PIC combinations. If you continue the installation, one or more PICs might appear to be online (the LEDs are on), but the Junos OS cannot enable them and they cannot pass traffic. As a workaround, you can:
• Install a Junos OS release that supports the combination.
• Install PICs on a different FPC.
- Remove PICs from the affected FPC.

T1600 Power System Description
The T1600 Core Router has two redundant, load-sharing power supplies, located at the lower rear of the chassis in slots PEM0 and PEM1 (top to bottom).
The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the T1600 router components, depending on their voltage requirements. For each output voltage that the power supply provides, it has either an active circuit breaker or an active current limiter.

NOTE: There are no passive fuses in the router that must be replaced.
Each power supply is cooled by its own internal cooling system. Power supplies are hot-removable and hot-insertable.
The T1600 router supports the power supplies in Table 62 on page 106.

NOTE: Redundant power supplies must be the same model number during normal operations.

T1600 Three-Input 240-A DC Power Supply
Each three-input 240-A DC power supply weighs approximately 25 lb (11.3 kg) and consists of three inputs, three 80-A circuit breakers, a fan, and LEDs to monitor the status of the power supply. Figure 39 on page 107 shows the three-input 240-A DC power supply.
Figure 39: Three-Input 240-A DC Power Supply

T1600 Three-Input 240-A DC Power Supply Inputs
The three-input 240-A DC power supply inputs are labeled INPUT 0, INPUT1, and INPUT 2, from top to bottom. Each input consists of -48 VDC and return—each with its own 80-A circuit breaker. The input mode switch on the faceplate allows you to set the DC power supply to either 2-INPUT or 3-INPUT mode. 3-INPUT mode is required for the T1600 Core Router.
Table 63 on page 107 describes which components are powered by each input.

T1600 Three-Input 240-A DC Power Supply Load Sharing and Fault Tolerance
When the T1600 router is operating normally and both power supplies are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply can provide full power for as long as the router is operational. Table 64 on page 108 describes the behavior of the power supply if one of the inputs fails.
Table 64: Fault Tolerance in Three-Input Mode
| Three-Input ModelInput | |
| INPUT 0 | If this input fails, INPUT 0, INPUT 1, and INPUT 2 shut down. The power supply shuts down, and the other power supply assumes the electrical load for all three inputs. |
| INPUT 1 | If this input fails, INPUT 0 is unaffected and INPUT 1 and INPUT 2 shut down. The other power supply assumes the electrical load of INPUT 1 and INPUT 2. |
| INPUT 2 | If this input fails, INPUT 0 is unaffected and INPUT 1 and INPUT 2 shut down. The other power supply assumes the electrical load of INPUT 1 and INPUT 2. |

Four-Input 240-A DC Power Supply Load Sharing and Fault Tolerance
When the router is operating normally and both power supplies are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply can provide full power for as long as the router is operational. If any of the four inputs fails, the router shuts down, and the other power supply assumes the electrical load for all four inputs.

T1600 Switch Interface Board (SIB) Description
SIBs create the switch fabric for the T1600 Core Router. Each T1600 router contains five SIBs located at the center rear of the chassis in the slots labeled SIB0 through SIB4 (top to bottom). One of the five SIBs acts as a backup to the remaining four SIBs. If a SIB fa the backup SIB becomes active, and traffic forwarding continues without any degradation. When the failed SIB is replaced, it becomes the new backup. SIBs are hot-insertable and hot-removable.
The T1600 router supports the SIBs listed in Table 71 on page 119

Two pairs of threaded inserts (PEM nuts) are provided on the right rear of the chassis for connecting the router to earth ground. The left pair of grounding points fits M6 screws
(European), and the right pair fits UNC 1/4–20 screws (American). The grounding points are spaced at 0.625-in. (15.86-mm) centers.
You must supply a grounding cable. The grounding cable must be 8-AWG ^2 , (8.35 mm minimum 90°C wire, or as required by the local code.
The accessory box shipped with the router includes one 4-AWG ^2 cable ring that attaches to the grounding cable (see Figure 56 on page 133). (The cable lug shown in Figure 56 on page 133 is also used for the DC power cables.) The accessory box includes two UNC 1/4–20 screws used to secure the grounding cable to the right pair of grounding points.

CAUTION: Before router installation begins, a licensed electrician must attach a cable lug to the grounding cable that you supply. A cable with an incorrectly attached lug can damage the router.

Rack Requirements for the T1600 Router
The router can be installed in many types of racks, including four-post (telco) racks and open-frame racks. An example of an open-frame rack is shown in Figure 57 on page 134.
For open-frame racks, center-mounting is preferable to front-mounting because the more even distribution of weight provides greater stability.
The router is designed for installation in a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association (http://www.eia.org).
With the use of adapters, the router can fit into a 600-mm-wide rack, as defined in the four-part Equipment Engineering (EE); European Telecommunications Standard for Equipment Practice (document numbers ETS 300 119-1 through 119-4) published by the European Telecommunications Standards Institute (http://www.etsi.org). Use approved wing devices to narrow the opening between the rails.
The rack rails must be spaced widely enough to accommodate the router chassis's external dimensions: 37.45 in. (95.1 cm) high, 31 in. (78.7 cm) deep, and 17.43 in. (44.3 cm)
wide, excluding the front and rear cable management systems. The outer edges of the mounting brackets extend the width to 19 in. (48.3 cm). The spacing of rails and adjacent racks must also allow for the clearances around the router and rack.
The mounting holes for connecting the mounting brackets to the chassis are spaced 0.984 in. (25 mm) apart.
The chassis height of 37.45 in. (95.1 cm) is approximately 21.4 U. A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association. You can stack two routers in a rack that has at least 42.8 U (74.9 in. or 1.90 m) of usable vertical space.
The rack must be strong enough to support the weight of the fully configured router, up to 606 lb (275 kg). If you stack two fully configured routers in one rack, it must be capable of supporting about 1212 lb (550 kg).
Figure 57: Typical Open-Frame Rack

Always secure the rack to the structure of the building. If your geographical area is subject to earthquakes, bolt the rack to the floor. For maximum stability, also secure the rack to ceiling brackets.

Clearance Requirements for Airflow and T1600 Hardware Maintenance
When planning the installation site, you need to allow sufficient clearance around the rack (see Figure 58 on page 135):
- For the cooling system to function properly, the airflow around the chassis must be unrestricted.

NOTE: If you mount the router in a cabinet, be sure that ventilation is sufficient to prevent overheating.
- For service personnel to remove and install hardware components, there must be adequate space at the front and back of the router. At least 24 in. (61 cm) are required both in front of and behind the router. NEBS GR-63 recommends that you allow at least 30 in. (72.6 cm) behind the rack.
• Additional clearance is required to accommodate the width and depth of the chassis with the optional rear cable management system:
• 2.4 in. (6.2 cm) additional width on the left side of the chassis
• 9.5 in. (24.1 cm) additional depth in the rear of the chassis

For each four-input 240-A power supply, we recommend that you provision at least 50 A @ -48 VDC per input. Although Input 0 and Input 1 in the four-input 240-A power supply require less power, we recommend provisioning the same amount of power for each input to avoid the possibility of connecting the lower-powered DC cables to Input 2 or Input 3.
For each six-input DC power supply, we recommend that you provision at least 56 A @ -48 VDC per input. Although Input 0 in the six-input DC power supply requires less power we recommend provisioning the same amount of power for each input to avoid the possibility of connecting the lower-powered DC cables to Input 1 through Input 5.
You must provision a circuit breaker for each DC power supply input rated for at least 125% of the continuous current that the system draws at -48 VDC.

T1600 DC Power Requirements
To allow for future growth so that you can operate the router in any hardware configuration without upgrading the power infrastructure, we recommend that you provision the following for each power supply.

NOTE: Although the power requirements for each input varies, we recommend that you provision the same amount of power for each input, or DC power cable when using terminal jumpers.
- Three-input 240-A DC power supply: 67 A @ -48 VDC per input
- Four-input 240-A power supply: 50 A @ -48 VDC per input
- Six-input power supply: 56 A @ -48 VDC per input
Table 84 on page 141 lists the power requirements for various hardware components. For PIC power requirements, see the T1600 Core Router Interface Module Reference.
You can use the information in Table 84 on page 141 and the T1600 Core Router Interface Module Reference to calculate power consumption for various hardware configurations, input current from a different source voltage, and thermal output, as shown in the following examples for a DC-powered router.

T1600 DC Power Distribution
Most sites distribute DC power through a main conduit that leads to frame-mounted DC power distribution panels, one of which might be located at the top of the rack that houses the router. A pair of cables (one input and one return) connects each set of terminal studs to the power distribution panel.

NOTE: All inputs on the DC power supply in slot PEMO must be powered by dedicated power feeds derived from feed A, and all inputs on the DC power supply in slotPEM1must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.
Figure 59 on page 143 shows a typical DC source cabling arrangement.

WARNING: For field-wiring connections, use copper conductors only.

CAUTION: Power cables must not block access to router components or drape where people could trip on them.

CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (−) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.
DC Power Lugs
The accessory box shipped with the T640 router includes eighteen 4-AWG ^2 (21.2 mm cable lugs for the DC cables that attach to the terminal studs of each power supply (see Figure 60 on page 145). the number of DC cables and cable lugs required varies depending on the power supply (see Table 86 on page 144). Each DC power cable requires one cable lug. One cable lug is also used for grounding the chassis. The cable lugs are dual hole, and sized to fit 1/4-20 UNC terminal studs at 15.86-mm (0.625-in.) center line.
Figure 60: DC Power Cable Lug


CAUTION: Before routerinstallation begins, a licensed electrician must attach a cable lug to the power cables that you supply. A cable with an incorrectly attached lug can damage the router.

T1600 AC Power Cord Specifications
Most sites distribute power through a main conduit that leads to frame-mounted power distribution panels, one of which can be located at the top of the rack that houses the router. An AC power cord connects each power supply to the power distribution panel.
Each AC power supply has a metal wiring compartment that contains the AC terminal block and ground labeled GND. The wye AC terminal block consists of four input terminals labeled L1, L2, L3, and N, from left to right. The delta AC terminal block consists of three input terminals labeled L1, L2, and L3, from left to right.
Detachable AC power cords, each 4.5 m (approximately 14.8 ft) long, are supplied with the router. The AC power cord wires insert into the AC input terminals in the AC terminal block by screwdriver. The plug end of the power cord fits into the power source receptacle for your geographical location.
Table 92 on page 151 provides specifications and Figure 61 on page 152 and
Figure 62 on page 152 depict the plug on the AC power cord provided for each region supported.

NOTE: In North America, AC power cords must not exceed 4.5 m (approximately 14.75 ft) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52, and Canadian Electrical Code (CEC) Section 4-010(3). The cords supplied with the router are in compliance.

WARNING: The router is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal (sized for UNC 1/4-20 ground lugs) provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth.

CAUTION: Power cords and cables must not block access to device components or drape where people could trip on them.

Understanding Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion
This topic describes signal loss, attenuation, and dispersion in fiber-optic cable. For information about calculating power budget and power margin for fiber-optic cable, see "Calculating Power Budget and Power Margin for Fiber-Optic Cables" on page 163 and "Supported Network Interface Standards by Transceiver for the ACX, M, MX, and T Series" on page 155 or Supported Network Interface Standards by Transceiver for PTX Series Packet Transport Routers.
• Signal Loss in Multimode and Single-Mode Fiber-Optic Cable on page 162
- Attenuation and Dispersion in Fiber-Optic Cable on page 162
Signal Loss in Multimode and Single-Mode Fiber-Optic Cable
Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. However, LEDs are not coherent sources. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles. Light rays travel in jagged lines through a multimode fiber, causing signal dispersion. When light traveling in the fiber core radiates into the fiber cladding, higher-order mode loss (HOL) results. Together these factors limit the transmission distance of multimode fiber compared with single-mode fiber.
Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber. Compared with multimode fiber, single-mode fiber has higher bandwidth and can carry signals for longer distances.
Exceeding the maximum transmission distances can result in significant signal loss, which causes unreliable transmission.
Attenuation and Dispersion in Fiber-Optic Cable
Correct functioning of an optical data link depends on modulated light reaching the receiver with enough power to be demodulated correctly. Attenuation is the reduction in
power of the light signal as it is transmitted. Attenuation is caused by passive media components, such as cables, cable splices, and connectors. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. An efficient optical data link must have enough light available to overcome attenuation.
Dispersion is the spreading of the signal in time. The following two types of dispersion can affect an optical data link:
- Chromatic dispersion—Spreading of the signal in time resulting from the different speeds of light rays.
- Modal dispersion—Spreading of the signal in time resulting from the different propagation modes in the fiber.
For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length. For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion rather than modal dispersion limits maximum link length.
An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications. In addition, the total dispersion must be less than the limits specified for the type of link in Telcordia Technologies document GR-253-CORE (Section 4.3) and International Telecommunications Union (ITU) document G.957.
When chromatic dispersion is at the maximum allowed, its effect can be considered as a power penalty in the power budget. The optical power budget must allow for the sum of component attenuation, power penalties (including those from dispersion), and a safety margin for unexpected losses.

Calculating Power Budget and Power Margin for Fiber-Optic Cables
Use the information in this topic and the information in "Supported Network Interface Standards by Transceiver for the ACX, M, MX, and T Series" on page 155 or Supported Network Interface Standards by Transceiver for PTX Series Packet Transport Routers to calculate the power budget and power margin for fiber-optic cables.
To calculate the power budget and power margin, perform the following tasks:
- Calculating Power Budget for Fiber-Optic Cable on page 163
- Calculating Power Margin for Fiber-Optic Cable on page 164
Calculating Power Budget for Fiber-Optic Cable
To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate the link's power budget, which is the maximum amount of power it can transmit. When you calculate the power budget, you use a worst-case analysis to provide a margin of error, even though all the parts of an actual system do not operate
at the worst-case levels. To calculate the worst-case estimate of power _3 budget (P you assume minimum transmitter power) (and minimum receiver sensitivity):(P
$$ P _ {B} = P _ {T} - P _ {R} $$
The following hypothetical power budget equation uses values measured in decibels (dB) and decibels referred to one milliwatt (dBm):
$$ P _ {B} = P _ {T} - P _ {R} $$
$$ P _ {B} = - 1 5 \mathrm{dBm} - (- 2 8 \mathrm{dBm}) $$
$$ P _ {B} = 1 3 \mathrm{dB} $$
Calculating Power Margin for Fiber-Optic Cable
After calculating a link's power budget, you can calculate the power margin (P represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget.) (PA worst-case estimate of assumes maximum LL:
$$ P _ {M} = P _ {B} - L L $$
AP_M greater than zero indicates that the power budget is sufficient to operate the receiver.
Factors that can cause link loss include higher-order mode losses (HOL), modal and chromatic dispersion, connectors, splices, and fiber attenuation. Table 95 on page 164 lists an estimated amount of loss for the factors used in the following sample calculations. For information about the actual amount of signal loss caused by equipment and other factors, refer to vendor documentation.
Table 95: Estimated Values for Factors Causing Link Loss
| Estimated Link-Loss ValueLink-Loss Factor | |
| Higher-order mode losses | Single-mode—NoneMultimode—0.5 dB |
| Modal and chromatic dispersion | Single-mode—NoneMultimode—None, if product of bandwidth and distance is less than 500 MHz-km |
| 0.5 dBConnector | |
| 0.5 dBSplice | |
| Fiber attenuation | Single-mode—0.5 dB/kmMultimode—1 dB/km |
The following example uses the estimated values in Table 95 on page 164 to calculate link loss (LL) for a 2-km-long multimode link with a power budget3(EB:
- Fiber attenuation for 2 km @ 1.0 dB/km = 2 dB
- Loss for five connectors @ 0.5 dB per connector = 5(0.5 dB) = 2.5 dB
- Loss for two splices @ 0.5 dB per splice = 2(0.5 dB) = 1 dB
• Higher-order mode loss = 0.5 dB
• Clock recovery module = 1 dB
The power margin _M P is calculated as follows:
$$ P _ {M} = P _ {B} - L L $$
$$ P _ {M} = 1 3 \mathrm{dB} - 2 \mathrm{km} (1. 0 \mathrm{dB/km}) - 5 (0. 5 \mathrm{dB}) - 2 (0. 5 \mathrm{dB}) - 0. 5 \mathrm{dB} [ \text {HOL} ] - 1 \mathrm{dB} [ \text {CRI} $$
$$ P _ {M} = 1 3 \mathrm{dB} - 2 \mathrm{dB} - 2. 5 \mathrm{dB} - 1 \mathrm{dB} - 0. 5 \mathrm{dB} - 1 \mathrm{dB} $$
$$ P _ {M} = 6 \mathrm{dB} $$
The following sample calculation for an 8-km-long single-mode link with a power budget ( P_B ) of 13 dB uses the estimated values from Table 95 on page 164 to calculate link loss (LL) as the sum of fiber attenuation (8 km @ 0.5 dB/km, or 4 dB) and loss for seven connectors (0.5 dB per connector, or 3.5 dB). The power marginal (Pulated as follows:
$$ P _ {M} = P _ {B} - L L $$
$$ P _ {M} = 1 3 \mathrm{dB} - 8 \mathrm{km} (0. 5 \mathrm{dB/km}) - 7 (0. 5 \mathrm{dB}) $$
$$ P _ {M} = 1 3 \mathrm{dB} - 4 \mathrm{dB} - 3. 5 \mathrm{dB} $$
$$ P _ {M} = 5. 5 \mathrm{dB} $$
In both examples, the calculated power margin is greater than zero, indicating that the link has sufficient power for transmission and does not exceed the maximum receiver input power.

Mounting the T1600 Chassis Using a Mechanical Lift
Because of the router's size and weight—up to 606 lb (275 kg) depending on configuration—we strongly recommend that you install the router using a lift.
To mount the chassis in the rack or cabinet using a lift (see Figure 71 on page 197):
-
If you are installing the router in an open-frame rack, ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation site allows adequate clearance for both airflow and maintenance. For details, see "Clearance Requirements for Airflow and T1600 Hardware Maintenance" on page 135.
-
Load the router onto the lift, making sure it rests securely on the lift platform.

CAUTION: Do not lift the router using the installation handle or the handles on the sides of the chassis. Use these handles only to help position the router.
- Using the lift, position the chassis in front of the rack or cabinet, centering it in front of the mounting shelves.
-
Lift the chassis approximately 0.75 in. above the surface of the mounting shelves and position it as close as possible to the shelves.
-
Carefully slide the chassis onto the mounting shelves so that the bottom of the chassis and the mounting shelves overlap by approximately 2 inches.
- With one person pulling on the installation handle from the rear of the rack or cabinet while two people push on the front-mounting flanges, slide the chassis onto the mounting shelves until the mounting brackets or front-mounting flanges contact the rack rails or spacer bars (depending on your type of installation). The shelves ensure that the holes in the mounting brackets and the front-mounting flanges of the chassis align with the holes in the rack rails.
- Move the lift away from the rack.
- If you are installing the router in a four-post rack or cabinet, install a mounting screw and a cage nut into each of the holes aligned with the threaded holes in the spacer bars. If you are installing the router in an open-frame rack, install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.
- Visually inspect the alignment of the router. If the router is installed properly in the rack, all the mounting screws on one side of the rack should be aligned with the mounting screws on the opposite side and the router should be level.

Connecting the T1600 Router to an External Alarm-Reporting Device
To connect the router to external alarm-reporting devices, attach wires to the RED ALARM and YELLOW ALARM relay contacts on the CIP. A system condition that triggers the red or yellow alarm LED on the craft interface also activates the corresponding alarm relay contact.
The terminal blocks that plug into the alarm relay contacts are supplied with the router. They accept wire of any gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm which is not provided. Use the gauge of wire appropriate for the external device you are connecting.
To connect an external device to an alarm relay contact:
- Prepare the required length of wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm).
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- While the terminal block is not plugged into the relay contact, use a 2.5-mm flat-blade screwdriver to loosen the small screws on its side. With the small screws on its side facing left, insert wires into the slots in the front of the block based on the wiring for the external device. Tighten the screws to secure the wire.
- Orient the terminal block according to the labels to the left of the appropriate relay contact (NC means "normally closed, C means "common," and (NO means "normally open").
- Plug the terminal block into the relay contact and use a 2.5-mm flat-blade screwdriver to tighten the screws on the face of the block.
- Attach the other end of the wires to the external device.
If attaching a reporting device for the other kind of alarm, repeat the procedure.

Connecting PIC Cables to the T1600 Router
The router supports PICs that use various kinds of network cable, including multimode and single-mode fiber-optic cable. For information about the type of cable used by each PIC, see the interface module reference for your device.
You connect PICs to the network by plugging in network cable. To connect cable to the PICs (see Figure 105 on page 237, which shows a fiber-optic PIC):
-
Have ready a length of the type of cable used by the PIC. For cable specifications, see "Supported Network Interface Standards by Transceiver for the ACX, M, MX, and T Series" on page 155 in the interface module reference for your device.
-
If the PIC cable connector port is covered by a rubber safety plug, remove the plug.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.
-
Insert the cable connector into the cable connector port on the PIC faceplate.
-
Arrange the cable in the cable management system to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

Connecting DC Power to the T1600 Router (Three-Input 240-A DC Power Supplies or Four-Input 240-A DC Power Supplies)
You connect DC power to the router by attaching power cables from the DC power sources to the terminal studs on the power supply faceplates. You must provide power cables (the cable lugs are supplied with the router).

CAUTION: All inputs on the DC power supply in slot PEM0 must be powered by dedicated powerfeedsderivedfromfeedA, and all inputs on the DC power supply in slot PEM1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.
To connect the DC source power cables to the router, follow this procedure for each DC power supply:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site. Switch off the customer site circuit breakers. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cable leads might become active during installation.
- Verify that a licensed electrician has attached the cable lugs provided with the router to the power cables.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Switch the circuit breakers on the power supply faceplate to the OFF position (O).
- Remove the clear plastic cover protecting the terminal studs on the faceplate.
- Remove the nut and washer from each power terminal stud. If no washers and nuts are already installed, they should be in the accessory box.
- Attach the lugs on the DC source power cables to the terminal studs. Secure the cable lugs to the terminal studs, first with the washers, then with the nuts. Using a 7/16-in. (11 mm) nut driver, tighten the nuts. Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.

CAUTION: You must use an appropriate torque-controlled tool to tighten the nuts. Applying excessive torque damages the terminal studs and the
power supply. The absolute maximum torque that may be applied to this nut is 45 lb-in. (5.0 Nm).
a. Attach the positive (+) DC source power cable lugs to the RTN (return) terminals.
b. Attach the negative (−) DC source power cable lugs to the -48V (input) terminals.

CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (−) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.
- Loosen the captive screw or screws on the cable restraint on the right edge of the power supply faceplate (using a Phillips (+) screwdriver, number 2).
- Route the positive and negative DC power cables through the cable restraint.
- Tighten the cable restraint captive screw or screws to hold the power cables in place.
- Verify that the power cabling is correct, that the power cables are not touching or blocking access to router components, and that they do not drape where people could trip on them.
- Replace the clear plastic cover over the terminal studs on the faceplate.

Powering On the AC-Powered T1600 Router
You can use this procedure for a router with either three-phase delta AC power supplies or three-phase wye AC power supplies. To power on the AC-powered router:
- Verify that the power supplies are fully inserted in the chassis and that the captive screws on their faceplates are tightened.
- Verify that the AC power cords are connected correctly.
- Verify that an external management device is connected to one of the Routing Engine ports on the CIP (AUXILIARY or CONSOLE).

NOTE: The management Ethernet port will not be functional until you have completed the initial configuration.
- Turn on the power to the external management device.
- Switch on the dedicated customer site circuit breakers to provide power to the AC power cables. Follow your site's procedures.
- Verify that the AC OK LED on both AC power supply faceplates are lit steadily green, indicating that the power supplies are receiving power.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Switch the power switch on one of the power supplies to the ON position (I). The DC OK LED blinks momentarily, then lights steadily.

NOTE: After a power supply is powered on, it can take up to 60 seconds forstatus indicators—such as the output statusLEDs on the power supply, the command output, and messages on the LCD on the craft interface—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
- Verify that the DC OK LED on the AC power supply faceplate is lit steadily, indicating that power supply is correctly installed, functioning properly, and providing power to the DC outputs.
- On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.

NOTE: If the system is completely powered off when youpoweronthepower supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting, you must power off the router before powering it on again. After powering on a power supply, wait at least 60 seconds before turning it off. After powering off a power supply, wait at least 60 seconds before turning it back on.

Initially Configuring the T1600 Router
The T1600 Core Router is shipped with Junos OS preinstalled and ready to be configured when the T1600 router is powered on. These procedures connect a router to the network but do not enable it to forward traffic. For complete information about enabling the router to forward traffic, including examples, see the Junos OS configuration guides.
You configure the router by issuing Junos OS command-line interface (CLI) commands, either on a console device attached to the CONSOLE port on the CIP, or over a telnet connection to a network connected to the ETHERNET port on the CIP.

NOTE: These procedures enable you to use the ETHERNET management port. For the initial configuration, use a device attached to the CONSOLE port on the CIP.
For more information about the commands in this procedure see the Junos OS Administration Library for Routing Devices.

- Removing a Two-Input 160-A DC Power Supply on page 281
• Installing a T1600 Power Supply on page 283
Removing a Two-Input 160-A DC Power Supply
The power supplies are located at the rear of the chassis below the SIBs. Each two-input 160-A power supply weighs approximately 23 lb (10.5 kg).

CAUTION: Do not leave a power supply slot empty for more than 30 minutes while the router is operational. For proper airflow, the power supply must remain in the chassis, or a blank panel must be used in an empty slot.
To remove a power supply:
- Make sure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cables might become active during the removal process.

CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (−) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.
-
For a nonredundant power supply, power off the system. See the T640 Core Router Hardware Guide. For redundant power supplies, check that the other power supply is functional.
-
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
-
Switch the circuit breakers on the power supply faceplate to the off position (O).

NOTE: After powering off a power supply, you must wait at least 60 seconds before turning it back on.
-
Remove the clear plastic cover protecting the terminal studs on the faceplate.
-
Remove the nuts and washers from the terminal studs (see Figure 121 on page 282). Use a 7/16-in. (11 mm) nut driver.
Figure 121: Disconnecting Power Cables from a Two-Input 160-A DC Power Supply

-
Remove the cable lugs from the terminal studs.
-
Loosen the captive screws on the cable restraints on the right edge of the power supply faceplate.
-
Carefully move the power cables out of the way.
-
Loosen the captive screws on the lower corners of the power supply faceplate completely. Twist the ejector handles on the upper corners of the faceplate counterclockwise to unseat the power supply.
-
Twist the ejector handles on the upper corners of the faceplate counterclockwise to unseat the power supply.
-
Grasp the handle on the power supply faceplate, and pull firmly to start removing the power supply. Slide it halfway out of the chassis (see Figure 122 on page 283).

WARNING: Do not touch the power connectors on the rear of the power supply (see Figure 123 on page 283). They can contain dangerous voltages.
- Place one hand underneath the power supply to support it and slide it completely out of the chassis.

CAUTION: Each two-input 160-A power supply weighs approximately 23 lb (10.5 kg). Be prepared to support the full weight of the power supply as you remove it from the router.

Upgrading to T1600 SIBs
To convert an operational T640 router to a T1600 router, you upgrade the standard SIBs or SIBs version B in the T640 router to T1600-SIBs or LCC-SIBs. You repeat the upgrade procedures for each of the five SIBs in the router.

NOTE: During the SIB upgrade:
- The router should not experience packet loss if the traffic is less than 50 percent per Packet Forwarding Engine in each FPC.
- The router might experience some packet loss if the traffic is more than 50 percent per Packet Forwarding Engine in each FPC, depending on the operational environment.
For more information, contact your customer support representative.

- Verifying Operation on page 290
Preparing to Upgrade the SIBs
To prepare to upgrade the SIBs:
- The T640 router must contain five standard SIBs or SIBs version B before the upgrade. Verify that four SIBs are in the Online state and one SIB is in the Spare state. Display the status of the SIBs by issuing the show chassis sibs command:
user@host> show chassis sibs
| Slot | State | Uptime |
| 0 | Spare | 255 days, 30 minutes, 12 seconds |
| 1 | Online | 255 days, 25 minutes, 45 seconds |
| 2 | Online | 255 days, 20 minutes, 28 seconds |
| 3 | Online | 255 days, 15 minutes, 7 seconds |
| 4 | Online | 255 days, 10 minutes, 52 seconds |
To bring a SIB online, issue the request chassis sib online operational mode command.
To install additional SIBs, use the standard installation procedure described in the T640 Core Router Hardware Guide.

NOTE: Do not proceed with the upgrade until all five SIBs are present and operational.
- Enter configuration mode.
user@host> configure
- Include the fabric upgrade-mode statement in the configuration at the [edit chassis] hierarchy level.
user@host# set chassis fabric upgrade-mode
-
Commit the configuration:
-
If GRES is enabled, commit the configuration on both the master and the backup Routing Engines:
user@host# commit synchronize -
If GRES is not enabled, commit the configuration on the master Routing Engine:
user@host# commit -
Exit configuration mode.
user@host# exit
Removing a Standard SIB or SIB Version B

NOTE: Replace the spare SIBfirst, and verify the operation of the replacement before replacing the other SIBs.
To remove a standard SIB or SIB version B:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
- Take the SIB offline by using one of the following methods:
- Press and hold the ONLINE/OFFLINE button on the SIB faceplate for about five seconds until the OK LED is not lit.
- Issue the request chassis sib offline command. For example:
user@host> request chassis sib offline slot 0

NOTE: When you bring an active SIB offline, the spare SIB becomes active and transitions to the Online state.
- Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the ejector handles on each side of the SIB faceplate.
- Flip the ejector handles outward to unseat the SIB.
- Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of the way out of the chassis.
- Place one hand underneath the SIB to support it and slide it completely out of the chassis. Place the SIB on the antistatic mat.

CAUTION: Do not stack hardware components on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.

Installing a T1600-SIB
Each T1600-SIB weighs approximately 6.5 lb (3 kg). To install a T1600-SIB (see Figure 126 on page 288):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
- Place one hand underneath the T1600-SIB to support it. With the other hand, hold one of the ejector handles on the T1600-SIB faceplate.
- Carefully align the sides of the T1600-SIB with the guides inside the chassis.
- Slide the T1600-SIB into the chassis, carefully ensuring that it is correctly aligned.
-
Grasp both ejector handles and press them inward to seat the T1600-SIB. Ensure that the ejector handle tabs are properly mated inside their corresponding chassis slots. You might have to close and open the handles a few times before the tabs catch the slots.
-
Tighten the captive screws on the ejector handles.
-
Bring the T1600-SIB online using one of the following methods:
-
Press and hold the ONLINE/OFFLINE button on the T1600-SIB faceplate. The green OK LED on the faceplate begins to blink. Hold the button down until the LED blinks.
- Issue the following CLI command on the router: user@host> request chassis sib online slot 0

To verify that the T1600-SIB is functioning normally:
-
Check the LEDs on the T1600-SIB faceplate.
-
The green OK LED should light steadily a few minutes after the T1600-SIB is installed.
-
If the FAIL LED is lit steadily, remove and install the T1600-SIB again. Make sure that the T1600-SIB is seated properly. If the FAIL LED still lights steadily, the T1600-SIB is not functioning properly. Contact your customer support representative.
-
Verify that four T1600-SIB are in the Online state and one SIB is in the Spare state.
Display the status of the T1600-SIB by issuing the show chassis sibs command:
user@host> show chassis sibs
| Slot | State | Uptime |
| 0 | Spare | 0 days, 30 minutes, 12 seconds |

T1600 Field-Replaceable Units
Field-replaceable units (FRUs) are router components that can be replaced at the customer site. Replacing most FRUs requires minimal router downtime. The router uses the following types of FRUs:
- Hot-removable and hot-insertable FRUs—You can remove and replace these components without powering off the router or disrupting the routing functions.
- Hot-pluggable FRUs—You can remove and replace these components without powering down the router, but the routing functions of the system are interrupted when the component is removed.

NOTE: Before you replace most host subsystem components, such as a control board or Routing Engine, you must take the host subsystem offline. However, it is not necessary to halt the host subsystem to insert or remove a PC card.
You must power off the Routing Engine before replacing a CompactFlash card or solid-state disk in a Routing Engine.
Table 103 on page 302 lists the FRUs for the router.

Taking the T1600 Host Subsystem Offline
Before you replace a control board or a Routing Engine, you must take the host subsystem offline. The host subsystem is taken offline and brought online as a unit. Normally, if two host subsystems are installed in the router, RE0 functions as the master and RE1 functions as the backup. Table 105 on page 349 explains the effect of taking the host subsystem offline.
Table 105: Effect of Taking the Host Subsystem Offline
| Type of Host Subsystem | Effect of taking the Host Subsystem Offline |
| subsystem | The router shuts down.Nonredundant host |
| Backup host subsystem | The functioning of the router is not interrupted. The backup host subsystem is hot-removable and hot-insertable. |
| Master host subsystem | The backup host subsystem becomes the master. The backup Routing Engine assumes Routing Engine functions. The master host subsystem is hot-pluggable. Removal or failure of the master Routing Engine affects forwarding and routing based on the high availability configuration:Dual Routing Engines without any high availability features enabled—Traffic is interrupted while the Packet Forwarding Engine is reinitialized. All kernel and forwarding processes are restarted. When the switchover to the new master Routing Engine is complete, routing convergence takes place and traffic is resumed.Graceful Routing Engine switchover (GRES) is enabled—Graceful Routing Engine switchover preserves interface and kernel information. Traffic is not interrupted. However, graceful Routing Engine switchover does not preserve the control plane. Neighboring routers detect that the router has restarted and react to the event in a manner prescribed by individual routing protocol specifications. To preserve routing without interruption during a switchover, graceful Routing Engine switchover must be combined with nonstop active routing.Nonstop active routing is enabled (graceful Routing Engine switchover must be configured for nonstop active routing to be enabled)—Nonstop active routing supports Routing Engine switchover without alerting peer nodes that a change has occurred. Nonstop active routing uses the same infrastructure as graceful Routing Engine switchover to preserve interface and kernel information. However, nonstop active routing also preserves routing information and protocol sessions by running the routing protocol process (rpd) on both Routing Engines. In addition, nonstop active routing preserves TCP connections maintained in the kernel.Nonstop active routing is supported on Junos OS Release 8.5 and later for standalone T1600 routers, Junos OS Release 10.0 and later for T1600 routers in a routing matrix.Graceful restart is configured—Graceful restart provides extensions to routing protocols so that neighboring helper routers restore routing information to a restarting router. These extensions signal neighboring routers about the graceful restart and prevent the neighbors from reacting to the router restart and from propagating the change in state to the network during the graceful restart period. Neighbors provide the routing information that enables the restarting router to stop and restart routing protocols without causing network reconvergence. Neighbors are required to support graceful restart. The routing protocol process (rpd) restarts. A graceful restart interval is required. For certain protocols, a significant change in the network can cause graceful restart to stop. |

NOTE: Router performance might change if the backup Routing Engine's configuration differs from the former master's configuration. For the most predictable performance, configure the two Routing Engines identically, except for parameters unique to each Routing Engine.

NOTE: For information about configuring gracefulRouting Engine switchover (GRES) and nonstop active routing, see the Junos OS High Availability Library for Routing Devices.
To take a host subsystem offline:
- Determine whether the host subsystem is functioning as the master or as the backup, using one of the two following methods:
- Check the Routing Engine LEDs on the craft interface. If the green MASTER LED is lit, the corresponding host subsystem is functioning as the master.
- Issue the following CLI command. The master Routing Engine is designated Master in the Current state field:
user@host> show chassis routing-engine
Routing Engine status:
Slot 0:
Current state Master
...
- If the host subsystem is functioning as the master, switch it to backup using the CLI command:
user@host> request chassis routing-engine master switch
- Halt the Routing Engine.
user@host> request system halt
Wait until a message appears on the console confirming that the operating system has halted.
The command shuts down the Routing Engine cleanly, so its state information is preserved.

- Replacing a T1600 PIC on page 384
- Replacing a T1600 PIC Cable on page 389
Replacing a T1600 FPC
The FPCs are hot-insertable and hot-removable. When you remove an FPC, the router continues to function, although the PIC interfaces installed on the FPC being removed no longer function.
- Removing a T1600 FPC on page 377
- Installing a T1600 FPC on page 380
Removing a T1600 FPC
The router holds up to eight FPCs, which are installed vertically in the front of the router. An empty FPC weighs approximately 25 lb (11.3 kg) and an FPC with PICs installed can weigh up to 37 lb (14.5 kg).
Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC blank panel weighs 7 lb (3 kg).
To remove an FPC (see Figure 185 on page 379):
- Place an electrostatic bag or antistatic mat on a flat, stable surface.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Use one of the following methods to take the FPC offline:
- Press and hold the FPC online/offline button. The green OK LED next to the button begins to blink. Hold the button down until the LED goes out. The LEDs and online/offline button for each FPC are located directly above it on the craft interface.
- Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the command, see request chassis fpc.
- Disconnect the cables from the PICs installed in the FPC. If a PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap. Arrange the disconnected cables in the cable management system, to prevent the cables from developing stress points.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- After you remove each PIC, immediately place it on an antistatic mat or in an electrostatic bag.
- If you are removing a Type 2 FPC or Type 3 FPC, loosen the screws inside the ejector handles at the top and bottom of the FPC faceplate.
- Simultaneously turn both the ejector handles counterclockwise to unseat the FPC.
- Grasp the handles and slide the FPC straight out of the card cage halfway.
- Place one hand around the front of the FPC (the PIC housing) and the other hand under it to support it. Slide the FPC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

CAUTION: The weight of the FPC is concentrated in the back end. Be prepared to accept the full weight—up to 37 lb (14.5 kg)—as you slide the FPC out of the chassis.
When the FPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.
Do not stack FPCs on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
- If you are not reinstalling an FPC into the emptied FPC slot within a short time, install a blank FPC panel over the slot to maintain proper airflow in the FPC card cage.

CAUTION: After removing an FPC from the chassis, wait at least 30 seconds before reinserting it, removing an FPC from a different slot, or inserting an FPC into a different slot.

CAUTION: TheFPCpower connectoris located in the corner where the bottom and the connector edges meet. If a power connector prong becomes bent, it no longer aligns with the female connector on the midplane, and the FPC no longer functions.
To install an FPC (see Figure 187 on page 383 and Figure 188 on page 384):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Place the FPC on an antistatic mat.
- Take each PIC to be installed in the replacement FPC out of its electrostatic bag and identify the slot on the FPC where it will be connected.
- Verify that each fiber-optic PIC has a rubber safety cap covering the PIC transceiver. If it does not, cover the transceiver with a safety cap.
- Install each PIC into the appropriate slot on the FPC. For information about installing a PIC, see "Installing a T1600 PIC" on page 387.
- Locate the slot in the FPC card cage in which you plan to install the FPC.
- Inspect the slot in the FPC card cage to verify that there are no missing or bent pins on the midplane.
- Inspect the FPC to verify that the connectors are not misaligned or damaged.
- Orient the FPC vertically with the component side facing to the right. Be sure the FPC is right-side up, with the components on the right of the FPC.

CAUTION: When the FPC is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.
-
Carefully align the connector edge of the FPC with the appropriate empty slot in the chassis.
-
Lift the FPC into place and carefully align the bottom and top of the FPC with the guides inside the card cage.
Figure 186: Installing an FPC

- Gently rest the bottom edge of the FPC on the bottom edge of the slot opening, making contact a short distance forward of the power connector.

CAUTION: Take care not to bend or otherwise damage the power connector prongs.
-
Slowly slide the FPC into the slot until you feel resistance.
-
Align the ejector handles on the FPC faceplate in a position close to horizontal.
-
Simultaneously turn both ejector handles clockwise until you cannot turn them farther.
-
If you are installing a Type 2 FPC or Type 3 FPC, tighten the screws inside the ejector handles to secure the FPC. Do not overtighten them.
-
If any of the PICs on the FPC connect to fiber-optic cable, remove the rubber safety cap from each transceiver and cable.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.
- Insert the appropriate cable into the cable connector ports on each PIC on the FPC. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop, using the cable management system. Placing fasteners on a loop helps to maintain its shape.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- Use one of the following methods to bring the FPC online:
- Press and hold the FPC online/offline button until the green OK LED next to the button lights steadily, in about 5 seconds. The LEDs and online/offline button for each FPC are located directly above it on the craft interface.
- Issue the following CLI command:
user@host>request chassis fpc slot slot-numberonline
For more information about the command, see request chassis pic.

CAUTION: After the OK LED lights steadily, wait at least 30 seconds before removing the FPC again, removing an FPC from a different slot, or inserting an FPC in a different slot.
You can also verify correct FPC and PIC functioning by issuing the show chassis fpc and show chassis fpc pic-status commands, as described in "Maintaining T1600 FPCs" on page 480 and "Maintaining T1600 PICs and PIC Cables" on page 488.

Removing a T1600 Three-Input 240-A DC Power Supply
To remove a three-input 240-A DC power supply:
- Switch off the external circuit breakers to the power supply being removed. Make sure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cables might become active during the removal process.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Switch the circuit breakers on the power supply faceplate to the off position (O).

NOTE: After powering off a power supply, wait at least 60 seconds before turning it back on.
-
Remove the clear plastic cover protecting the terminal studs on the faceplate.
-
Using a 7/16-in. (11 mm) nut driver or wrench, remove the nuts and washers from the terminal studs (see Figure 192 on page 395).

CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (−) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.

Removing a T1600 DC Power Supply Cable From a Six-Input DC Power Supply
To remove a DC power supply cable from a six-input DC power supply:
-
Switch off the customer site circuit breakers for all the cables attached to the power supply. Make sure that the voltage across the DC power source cable leads is 0 V and that there is no chance that the cables might become active during the removal process.
-
Remove the power cable from the external DC power source.
-
Remove the clear plastic cover protecting the terminal studs on the faceplate.
-
Remove the nut and washer from the terminal stud on the power supply (see Figure 218 on page 422). Use a 7/16-in. (11 mm) nut driver.
Figure 218: Disconnecting the DC Power Cable

- Remove the cable lug from the terminal stud on the power supply.
- Loosen the captive screw or screws on the cable restraint on the right edge of the power supply faceplate.

Installing a T1600 DC Power Supply Cable on a Six-Input DC Power Supply
To install a DC power supply cable on a six-input DC power supply:
- Locate a DC power cable that meets the specifications for the power supply.

CAUTION: A licensed electrician must attach a cable lug to the power cable that you supply. A cable with an incorrectly attached lug can damage the router.
- Route the power cable through the appropriate cable restraint.
- Attach the lug on the DC source power cable to the terminal stud.
a. Attach a negative (−) DC source power cable lug to the −48V (input) terminals.
b. Attach a positive (+) DC source power cable lug to the RET (return) terminals.
Secure the cable lug to the terminal stud, first with a washer, then with a nut (see Figure 219 on page 423). Use a 7/16-in. (11-mm) nut driver to tighten the nut. Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.

CAUTION: You must use an appropriate torque-controlled tool to tighten the nuts. Applying excessive torque damages the terminal studs and the power supply. The absolute maximum torque that may be applied to this nut is 45 lb-in. (5.0 Nm).
Figure 219: Connecting the DC Power Cable

- Tighten the cable restraint captive screw or screws to hold the power cable in place.
- Replace the clear plastic cover over the terminal studs on the faceplate.
- Verify that the DC source power cabling is correct, that the power cable is not touching or blocking access to router components, and that it does not drape where people could trip on it.
- Attach the other end of the power cable to the external DC power source.
- Switch on the customer site circuit breakers.
- Verify that the INPUT PRESENT LEDs on the power supply faceplate are lit steadily, indicating that the inputs are receiving voltage.
- Switch the power switch on the power supply to the ON position (I). The DC OK LED blinks momentarily, then lights steadily.

NOTE: After a power supply is powered on, it can take up to 60 seconds forstatus indicators—such as the LEDs on the power supply, the command output displays, and messages on the LED display on the craft interface—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
- Verify that the DC OK LED on the power supply faceplate is lit steadily, indicating that the power supply is correctly installed and is functioning properly.

- Installing a T1600 SFP on page 464
Removing a T1600 SFP
Small form-factor pluggables (SFPs) are transceivers that can be removed from a PIC. SFPs are hot-insertable and hot-removable. Removing an SFP does not interrupt PIC functioning, but the removed SFP no longer receives or transmits data.

NOTE: When you remove a PIC transceiver, the router continues to function, although the PIC interface being removed no longer functions.
Figure 250: Small Form-Factor Pluggable (SFP)


NOTE: This procedure applies to both SFP and SFP+ transceivers.
To remove an SFP transceiver (see Figure 250 on page 463):
- Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the SFP. Have ready a rubber safety cap for the SFP transceiver and the cable.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Label the cable connected to the SFP so that you can later reconnect it to the correct SFP.
- Disconnect the cable from the SFP. Immediately cover the transceiver and the end of the cable with a rubber safety cap.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.
- Arrange the cable in the cable management system to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight
as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- Pull the ejector handle away from the SFP faceplate to unseat the SFP from the PIC. Pull the SFP out of the PIC, and place it on the antistatic mat or in the electrostatic bag.

CAUTION: After removing a transceiver from the chassis, wait at least 30 seconds before reinserting it or inserting a transceiver into a different slot.
Installing a T1600 SFP
To install a replacement SFP:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Verify that a rubber safety cap covers the SFP transceiver, installing one if necessary.
-
Orient the SFP over the port in the PIC so that the connector end will enter the slot first and the SFP connector faces the appropriate direction:
-
If the PIC has ten SFP ports, the ports are arranged in two columns. The SFP connector faces to the right for ports in the left column, and to the left for ports in the right column.
-
If the PIC has one or two SFP ports, the SFP connector faces to the left.
-
Slide the SFP into the slot. If there is resistance, remove the SFP and flip it so that the connector faces the other direction.
- Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes.

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.
- Arrange the cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coil loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- Verify that the status LEDs on the PIC faceplate indicate that the SFP is functioning correctly (there is an LED for each SFP port). For more information about the PIC LEDs, see the interface module reference for your device. You can also verify PIC functioning by issuing the show chassis fpc plc-status command.

Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- Pull the ejector handle away from the XFP faceplate to unseat the XFP from the PIC. Pull the XFP out of the PIC and place it on the antistatic mat or in the electrostatic bag.
Installing a T1600 XFP
To install a replacement XFP:
-
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
-
Verify that a rubber safety cap covers the XFP transceiver, installing one if necessary.
-
Orient the XFP over the port in the PIC so that the connector end will enter the slot first and the XFP connector faces the appropriate direction.
-
Slide the XFP into the slot. If there is resistance, remove the XFP and flip it so that the connector faces the other direction.
-
Remove the rubber safety cap from the transceiver and the end of the cable, and insert the cable into the transceiver.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected to a transceiver emit laser light that can damage your eyes..

CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.
- Arrange the cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coil loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.

CAUTION: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.

CAUTION: Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.
- Verify that the status LEDs on the PIC faceplate indicate that the XFP is functioning correctly (there is an LED for each XFP port). For more information about the PIC LEDs, see the T1600 Core Router Interface Module Reference. You can also verify PIC functioning by issuing the show chassis fpc pic-status command described in "Maintaining T1600 PICs and PIC Cables" on page 488.

Maintaining the T1600 Air Intake Vents
Purpose For optimum cooling, verify the condition of the air intake vents. Dust can clog air intake vents, reducing cooling system efficiency.
Action On a regular basis, check the vents and clean them as necessary.
Related Documentation Clearance Requirements for Airflow and T1600 Hardware Maintenance on page 135. •T1600 Cooling System Description on page 37
Maintaining the T1600 Air Filters
Purpose For optimum cooling, verify the condition of the air filters.
Air filters for both the front and rear fan trays help keep dust and other particles from entering the cooling system. To function properly, the entire cooling system requires an unobstructed airflow and proper clearance around the site, as described in "Clearance Requirements for Airflow and T1600 Hardware Maintenance" on page 135.
Figure 253: Airflow Through the Chassis

Action Check the air filters regularly for dust and debris. The filter elements degrade over time, so the filter elements in use, must be replaced every 6 months. For procedures to replace the air filters, see "Replacing the T1600 Rear Air Filter" on page 307 and "Replacing the T1600 Front Air Filter" on page 305.
Use spare filter elements within one year of manufacture. Check the date of manufacture printed on the filter. Store spare filter elements in a dark, cool, and dry place. Storing the filter elements at higher temperatures, or where they can be exposed to ultraviolet (UV) radiation, hydrocarbon emissions, or vapors from solvents, can significantly reduce their life.

CAUTION: Always keep both air filters in place while the router is operating. Because the fans are very powerful, they could pull small bits of wire or other materials into the router through the unfiltered air intake. This could damage the router components.

Maintaining the T1600 Control Boards
Purpose For optimum router performance, verify the condition of the control boards.
Action On a regular basis:
- Check the host subsystem LEDs on the craft interface. For more information about the LEDs and the display, see "T1600 Craft Interface Description" on page 31.
During normal operations:
- The green host subsystem OK LED on the craft interface is lit.
- The red host subsystem OK LED on the craft interface is not lit.
- Check the LEDs on the control board faceplate.
During normal operations:
•The green OK LED on the control board faceplate is lit.
- The yellow FAIL LED on the control board faceplate is not lit.
- Issue the show chassis environment cb command to check the status of the T-CBs.

Maintaining the T1600 Fan Trays
Purpose For optimum cooling, verify the condition of the fans.
Action On a regular basis:
- Monitor the status of the fans. The fan trays each contain multiple fans that work in unison to cool the router components. If one fan fails, the host subsystem adjusts the speed of the remaining fans to maintain proper cooling. A red alarm is triggered when a fan fails, and a yellow alarm is triggered when a fan tray is removed. During normal operation, the fans in each fan tray function at normal speed.
- To display the status of the fans, issue the show chassis environment or show chassis fan command.
For the standard fan trays, the output for the show chassis environment command is similar to the following:

Preventing Damage to FPCs

CAUTION: Many components on the FPC are fragile. Failure to handle FPCs as specified in this document can cause irreparable damage.

CAUTION: To prevent damage when handling or carrying FPCs:
- As you carry the FPC, do not bump it against anything. FPC components are fragile.
- Do not grasp the FPC anywhere except places that this document indicates. In particular, never grasp the connector edge, especially at the power connector in the corner where the connector and bottom edges meet (see Figure 254 on page 482).
- Do not carry the FPC by the faceplate with only one hand (see Figure 255 on page 482).
- Do not rest any edge of an FPC directly against a hard surface (see Figure 256 on page 483). If you must rest the FPC temporarily on an edge while changing its orientation between vertical and horizontal, use your hand as a cushion between the edge and the surface.

NOTE: An FPC configured with PICs installed can weigh as much as 37 lb (14.5 kg). Be prepared to accept the full weight of the FPC as you lift it.
You hold an FPC vertically when installing it into the chassis. To hold an FPC vertically (see Figure 257 on page 484):
- Orient the FPC so that the faceplate faces you.
- Place one hand around the FPC faceplate about a quarter of the way down from the top edge. To avoid deforming the electromagnetic interference (EMI) shielding strip, do not press hard on it.
- Place your other hand at the bottom edge of the FPC. If the FPC has heat sinks about midway between the faceplate and connector edge, place your other hand against the heat sinks.
Figure 257: Holding an FPC Vertically

Holding T1600 FPCs Horizontally
To hold an FPC horizontally:
- Orient the FPC so that the faceplate is facing you.
- Grasp the top edge with your left hand and the bottom edge with your right hand.
You can rest the faceplate of the FPC against your body as you carry it (see Figure 258 on page 485.

•Replacing a T1600 FPC on page 377
•Storing T1600 FPCs on page 485
Storing T1600 FPCs
When an FPC is not installed in a router, the FPC must be either stored in the container in which a spare FPC is shipped or stored horizontally with the component-side up on a flat, stable surface. When you store an FPC on a horizontal surface or in the shipping container, always place it inside an antistatic bag. Because the FPC is heavy and because antistatic bags are fragile, inserting the FPC into the bag is easier with two people. The storage procedures are as follows:
- When storing an FPC with two people, one person holds the FPC in the horizontal position with the faceplate facing their body, the other person slides the opening of the bag over the FPC connector edge.
- When storing an FPC with one person, you must insert the FPC into a bag by yourself. First lay the FPC horizontally on a flat, stable surface, component-side up. Orient the FPC with the faceplate facing you. Carefully insert the FPC connector edge into the opening of the bag, and pull the bag toward you to cover the FPC.

CAUTION: To prevent damage when storing FPCs:
- Never lay an FPC component-side down.

- Check the LEDs on PIC faceplates. A PIC LED lit green indicates the PIC is functioning normally. The meaning of the LED states differs for various PICs. For more information, see the interface module reference for your device. If the FPC that houses the PIC detects a PIC failure, the FPC generates an alarm message to be sent to the Routing Engine.
- Issue the CLI show chassis fpc pic-status command. The PIC slots in an FPC are numbered from 0 through 3, top to bottom:

- Use the cable management system to support cables and prevent cables from dislodging or developing stress points.
- Place excess cable out of the way in the cable management system. Do not allow fastened loops of cable to dangle from the connector or cable management system, because this stresses the cable at the fastening point. Putting fasteners on the loops helps to maintain their shape.
- Keep the cable connections clean and free of dust and other particles, which can cause drops in the received power level. Always inspect cables and clean them if necessary before connecting an interface.
- Label both ends of PIC cables to identify them.
The following guidelines apply specifically to fiber-optic cable:
- When you unplug a fiber-optic cable from a PIC, always place a rubber safety plug over the transceiver on the PIC faceplate and on the end of the cable.
- Anchor fiber-optic cable to avoid stress on the connectors. When attaching fiber to a PIC, be sure to secure the fiber so it is not supporting its own weight as it hangs to the floor. Never let fiber-optic cable hang free from the connector.
- Avoid bending fiber-optic cable beyond its bend radius. An arc smaller than a few inches can damage the cable and cause problems that are difficult to diagnose.
- Frequent plugging and unplugging of fiber-optic cable into and out of optical instruments, such as ATM or SONET/SDH analyzers, can cause damage to the instruments that is expensive to repair. Instead, attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easy and inexpensive to replace.
- Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the canal of the transceiver or cable connector could cause loss of light, reducing signal power and possibly causing intermittent problems with the optical connection.
To clean the transceivers, use an appropriate fiber-cleaning device, such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions for the cleaning kit you use.
After you have cleaned the transceiver on the fiber-optic PIC, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit, such as the Optex CableCleaner. Follow the directions for the cleaning kit you use.

Maintaining the T1600 Power Supplies
Purpose For optimum router performance, verify the condition of the power supplies.
Action On a regular basis:
- Make sure that the power and grounding cables are arranged so that they do not obstruct access to other router components.
•The power supplies require an unobstructed airflow at both the front and rear of the chassis. Periodically check the site to ensure that both the air intake at the bottom front of the chassis and the exhaust from the power supply faceplates are unobstructed.
- Periodically inspect the site to ensure that the grounding and power cables connected to the router are securely in place and that no moisture accumulating near the router. To review grounding and site wiring requirements for the router, see "T1600 Chassis Grounding Cable and Lug Specifications" on page 132 and "Site Electrical Wiring Guidelines for Juniper Networks Devices" on page 584.
•Regularly inspect the air filters on each power supply for dust and debris, and replace the side filter on AC power supplies or front filter element on AC and DC power supplies every 6 months.
To replace a power supply air filter element, see the following topics:
•Replacing a Front Air Filter on a T1600 AC or Three-Input 240-A or Four-Input 240-A DC Power Supply on page 415
*Replacing a Side Air Filter on a T1600 AC Power Supply
•Replacing a T1600 Six-Input DC Power Supply Front Air Filter on page 423
•Replacing a T1600 Six-Input DC Power Supply Side Air Filter on page 424
•Routinely check the LEDs on the DC power supply faceplates.
During normal operation:
- For DC power supplies, the blue DC OK LEDs light to indicate that the power supplies are functioning normally.
- For DC power supplies, each green INPUT PRESENT LED on a DC power supply lights when the input is receiving source DC power.
- For three-input 240 -A power supplies and four-input 240 -A DC power supplies, each CB ON LED on a DC power supply lights when the circuit breaker is on.
- Routinely check the LEDs on the AC power supply faceplates. If the AC OK LEDs are lit, the AC terminal blocks are receiving power. If the DC OK LEDs are lit, the AC power supplies are functioning normally.
- Check the red and yellow alarm LEDs and the LCD on the craft interface. Power supply failure or removal triggers an alarm that causes one or both of the LEDs to light and an error message to appear on the LCD. You can display the associated error messages by issuing the following CLI command:
user@host> show chassis alarms
- Issue the show chassis environment pem command to check the status of the power supplies.
•For DC-powered routers with three-input 240-A DC power supplies or four-input 240-A DC power supplies, the output is similar to the following:

| FPC 6 | 0 | 0 | 0 | 0 |
| FPC 7 | 0 | 0 | 0 | 0 |
| SCG/CB/SIB | 0 | 0 | 0 | 0 |
If 0 is displayed for the SCG/CB/SIB in the Current, Power, and Load fields for a PEM, and the voltage field does not match the other PEM, it might indicate a difference between the DC input voltages applied to PEM0 and PEM1. Consider checking your DC power network for unintended voltage drops to the router (see Figure 59 on page 143 for a typical DC source cabling arrangement).
The current sharing between DC power supplies relies on equal voltages at the input terminals of the power supplies. However, if the voltages do not match, the router operates normally as long as the DC input voltages are within the operating range provided in Table 80 on page 137.
- For the three-input 240-A DC power supplies, system power is divided into two load zones. One load zone consists of INPUT 0 of PEMO and PEM1. The other load zones consist of INPUT 1 and INPUT 2 of PEMO and PEM1. Load sharing occurs between the two power supplies for each load zone. Therefore, the input voltage for the inputs in each load zone must be equal in both power supplies for current sharing. For example, the input voltage for INPUT 0 of PEMO and the input voltage for INPUT 0 of PEM1 must be the same for current sharing to occur within that load zone.
- For the four-input 240-A DC power supplies, system power is divided into four load zones. One load zone consists of INPUT 0 of PEM0 and PEM1. The other load zones consist of INPUT 1, INPUT 2 and INPUT 3 of PEM0 and PEM1. Load sharing occurs between the two power supplies for each load zone. Therefore, the input voltage for the inputs in each load zone must be equal in both power supplies for current sharing. For example, the input voltage for INPUT 0 of PEM0 and the input voltage for INPUT 0 of PEM1 must be the same for current sharing to occur within that load zone.
•For DC-powered routers with six-input DC power supplies, the output is similar to the following:

Cleaning Fiber-Optic Array Components with the Dry Cloth Cleaning Tool

NOTE: This procedure is required only for TX Matrix Plus components and T1600 routers in a routing matrix. It is not required for fiber-optic ports on the PICs.
As part of your routine maintenance, we recommend that you clean all exposed fiber-optic array components each time you disconnect and reconnect a fiber-optic array cable, or if the optical link is not functioning correctly.

NOTE: While you install the router or replace a fiber-optic array cable, small deposits of oil, dust, and debris can enter the fiber-optic array ports, the fiber-optic array cable connectors, and the loopback connectors and adapters used to test the optical connections. These deposits can cause loss of light, reducing signal power and causing intermittent problems with the optical connection.
The following tools for cleaning the fiber-optic components are provided in the TX Matrix Plus tool kit:
- Dry cleaning tool (see Figure 260 on page 497). This tool uses a dry cloth to remove dust and oil from the fiber optics.
- Cleaning tool adapter
- Cleaning tool connector
Figure 260: Cleaning Tool

To clean the fiber-optic components using the dry cloth cleaning tool:
-
Take the TX Matrix Plus switching plane offline. See the TX Matrix Plus Router Hardware Guide.
-
Bring the TXP-F13 SIB offline by pressing the SFC ONLINE/OFFLINE button.
-
Bring the TXP-T1600 SIB offline by pressing the ONLINE/OFFLINE button.
-
Disconnect the fiber-optic array cable between the TXP-F13 SIB and TXP-T1600 SIB.

WARNING: Do not look directly into a fiber-optic array port or a connector at the end of a fiber-optic array cable connected to a port. The fiber optics emit laser light that can damage your eyes.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
-
Remove the dust cap from the fiber-optic array port. Open the dust shutter on the fiber-optic array port, and insert a cleaning adapter (see Figure 261 on page 498).
-
Remove the dust cap from the cleaning tool.
- Insert the tip of the dry cloth cleaning tool into the cleaning adapter (see Figure 261 on page 498).

T1600 Troubleshooting Resources
To troubleshoot a T1600 router, you use the Junos OS command-line interface (CLI), LCD, alarms, devices connected to the alarm relay contacts on the CIP, and LEDs on both the components and craft interface.
- LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate. In addition, you can also use the component-specific LEDs on the craft interface and on the faceplate of a component to troubleshoot the routing matrix.
- LCD—When a red or yellow alarm occurs, the cause of the alarm messages is displayed on the craft interface LCD. Use the CLI to display more information about the alarm.
- Alarm devices connected to the alarm relay contact on the CIP—When a red or yellow alarm occurs, it trips the corresponding alarm relay contact on the CIP.
- CLI—The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS, routing protocols, and network connectivity. CLI commands display information from routing tables, information specific to routing protocols, and information about network connectivity derived from the ping and traceroute utilities.
For information about using the CLI to troubleshoot Junos OS, see the appropriate Junos OS configuration guide.
- JTAC—If you need assistance during troubleshooting, you can contact the Juniper Networks Technical Assistance Center (JTAC) by using the Web or by telephone. If you encounter software problems, or problems with hardware components not discussed here, contact JTAC.

The craft interface displays system status messages and allows you to troubleshoot the T1600 router. The craft interface is located on the upper front of the router. It contains LEDs, buttons, and an LCD display showing status messages for the router.
LEDs on the craft interface include the following:
- Alarm LEDs—One large red circular LED and one large yellow triangular LED, located on the upper left of the craft interface, indicate two levels of alarm conditions. You can determine the cause of the alarm condition by looking at the LCD on the craft interface.
See "T1600 Craft Interface Alarm LEDs and ACO/LT Button" on page 33.
- Host subsystem LEDs—Three LEDs (one green MASTER, one green OK, and one red FAIL) indicate the status of each host subsystem. The host subsystem LEDs are located on the upper right of the craft interface, and are labeled HOST0 and HOST1.
See "T1600 Craft Interface Host Subsystem LEDs" on page 34.
- SIB LEDs—Two LEDs (one red FAIL and one green OK) indicate the status of each SIB. The SIB LEDs are located on the upper right of the craft interface, and are labeled SIB0 through SIB4.
See "T1600 Craft Interface SIB LEDs" on page 35.
- FPC LEDs—Two LEDs (one red FAIL and one green OK) indicate the status of each FPC. The FPC LEDs are located along the bottom edge of the craft interface, and are labeled FPC0 through FPC7.
See "T1600 Craft Interface FPC LEDs" on page 35.
Component LED Overview
The following LEDs are located on various router components and display the status of those components:
- Connector interface panel (CIP) LEDs—Two small LEDs on the left edge of the ETHERNET port on the CIP indicate the connection in use.

NOTE: When RE-C1800 are installed, the LEDs are always yellow for both a 10-Mbps connection and 100-Mbps connection.
See "T1600 Connector Interface Panel (CIP) LEDs" on page 27.
- SIB LEDs—Three LEDs on each SIB faceplate—ACTIVE, OK, and FAIL—indicate the status of that SIB.
See "T1600-SIB LEDs" on page 121 and "TXP-T1600 SIB LEDs" on page 122.

T1600 Alarm Messages Overview
When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the craft interface as appropriate, trips the corresponding alarm relay contact on the CIP, and reports the cause of the alarm in the craft interface LCD. To view a more detailed description of the alarm cause, issue the show chassis alarms CLI command:
user@host> show chassis alarms
There are two classes of alarm messages:
- Chassis alarms indicate a problem with a chassis component such as the cooling system or power supplies.

Troubleshooting the T1600 Cooling System
Problem Description:
The following alarms, LEDs, and other conditions indicate a problem with the cooling system:
•A red alarm indicates that temperature of the router exceeds the maximum ("temperature hot") threshold.
- Automatic shutdown of the power supplies was caused by the temperature of the router exceeding the maximum ("temperature hot") threshold. The control board turns off the power supplies because the router temperature exceeds the acceptable maximum.
•A red alarm indicates that a fan failed.
- A yellow alarm indicates that the router temperature exceeds the "temperature warm" threshold.
• A yellow alarm indicates that one of the fan trays was removed.
- One or more fans in a fan tray function at full speed. The control boards constantly monitor the temperatures detected by sensors on the midplane and router components, adjusting the speed of the fans as necessary.
In Table 107 on page 508, the text in the column labeled "LCD Message" appears in the display of the craft interface. The text in the column labeled "CLI Message" appears in the output from the show chassis alarms command.

Solution To troubleshoot the cooling system:
- Place your hand near the exhaust vents at the rear of the chassis to determine whether the fans are pushing air out of the chassis.
- If the red alarm LED on the craft interface lights, look at the craft interface display to find the source of the problem. The number of alarm conditions, as well as the source of each alarm, appears on the screen.
- If the craft interface display lists only one fan failure and the other fans are functioning normally, the fan is probably faulty and you need to replace the fan tray.
- Use the CLI to check the status of the fans. For example, you can issue the following command to get information about the source of an alarm condition:
user@host> show chassis alarms

Troubleshooting the T1600 Power System
Problem Description:
The following alarms, LEDs, and other conditions indicate a problem with the power system:
- If all power supplies have failed, the system temperature might have exceeded the threshold, causing the system to shut down.
- The blue DC OK LED blinks when a power supply detects a fault (the power supply fails, does not have sufficient airflow, is going through a startup test, or is not properly inserted).
- The yellow OVER TEMP LED lights when a power supply is not receiving enough airflow to maintain proper temperature.
- The green AC OK LED is off when an AC power supply is not receiving voltage.
In Table 112 on page 516, the text in the column labeled "LCD Message" appears in the display of the craft interface. The text in the column labeled "CLI Message" appears in the output from the show chassis alarms command.

Solution 1. Check the LEDs on each three-input 240-A DC or four-input 240-A DC power supply faceplate.
- DC OK power supply LED is blinking—Check the red alarm LED on the craft interface.
- DC OK power supply LED is off and no red alarm condition exists—Check that the circuit breakers are switched to the ON position (I).
-
DC OK LED on one or both of the power supplies is not lit—Check the power supply fans to see if they are operating.
• OVERTEMP LED on one of the power supplies lights—Check the fans and air filters to be sure they are functioning and providing sufficient airflow through the chassis. -
Check the LEDs on each six-input DC power supply faceplate.
-
The DC OK LED on one or both of the power supplies is not lit—Check that the power switch is on.
- The OVER TEMP LED on one of the power supplies is lit—Check the fan trays and air filters to be sure they are functioning and providing sufficient airflow through the chassis.
-
An INPUT PRESENT LED on a DC power supply is not lit—Check that the input is receiving source DC power.
-
Check the LEDs on each three-phase delta or wye power supply faceplate.
-
AC OK power supply LED is off—Check that the power supply is receiving voltage.
- DC OK power supply LED is blinking—Check the red alarm LED on the craft interface.
-
DC OK LED on one or both of the power supplies is not lit—Check the power supply fans to see if they are operating.
• OVERTEMP LED on one of the power supplies lights—Check the fans and air filters to be sure they are functioning and providing sufficient airflow through the chassis. -
Check the display on the craft interface to determine the source of a yellow or red alarm (see Table 112 on page 516). Junos OS constantly updates the screen with status information for each component.

NOTE: On the display and in the CLI, the power supplies are referred to as PEMO and PEMO, from top to bottom.
If the system temperature exceeds the threshold, Junos OS shuts down all power supplies so that no status is displayed.
Junos OS also can shut down one of the power supplies for other reasons. In that case, the remaining power supply assumes the load, and you can still view the system status through the CLI or display.
- Verify that the source circuit breaker has the proper current rating.

NOTE: All inputs on a DC power supply in slot PEM0 must be powered by dedicated power feeds derived from feed A, and all inputs on a DC power supply in slot PEM 1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.

NOTE: The AC power cord on an AC power supply in slot PEM0 must be powered by a dedicated power feed derived from feed A, and The AC power cord on an AC power supply in slot PEM 1 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.
- Verify that the DC power cables or AC power cord from the power source to the router are not damaged. If the insulation is cracked or broken, immediately replace the DC power cable or AC power cord.
- Connect the power supply to a different power source with a new DC power cable or AC power cord. If the power supply DC OK LED still does not light, the power supply is the source of the problem. Replace the power supply with a spare.
DC OK LED on the installed spare does not light—the replaced power supply might be faulty. To return it for replacement, see "Contacting Customer Support" on page 529. - If you cannot determine the cause of the problem or need additional assistance, see "Contacting Customer Support" on page 529.

Testing a Fiber-Optic Array Switching Plane Port
Four fiber-optic array loopback connectors are shipped in the tool kit with the TX Matrix Plus router (see Figure 264 on page 523).

NOTE: Use the loopback connectors to test the TXP-F13 ports.
Figure 264: TX Matrix Plus Fiber-Optic Array Switching Plane Loopback Connector and Loopback Adapter


CAUTION: Do not connect and disconnect the fiber-optic array switching plane cable connectors, loopback connectors, or loopback adapters more frequently than required to perform the procedures in this hardware guide. These fiber-optic components are rated for a limited number of insertions (approximately 100).
To use the loopback connectors to test the TXP-F13 SIB fiber-optic array switching plane ports:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Take the switching plane offline.
See Taking a Switching Data Plane Offline in the TX Matrix Plus Router Hardware Guide. - Bring the TXP-F13 SIB offline by pressing the SFC ONLINE/OFFLINE button.
- Remove the dust covers from the loopback connectors and from the fiber-optic array switching plane ports. Temporarily store the dust covers in a dust-free resealable plastic bag.

CAUTION: During maintenanceor replacementprocedures,small deposits of oil, dust, and debris can enter the TXP-F13 SIB and TXP-T1600 SIB
fiber-optic array switching plane ports, the fiber-optic array switching plane cable connectors, and the loopback connectors and adapters.
- Align a loopback connector with each TXP-F13 SIB fiber-optic array switching plane port, and carefully press it into the port until it stops. The loopback connector and fiber-optic array switching plane port are keyed to ensure proper mating.
- Bring the TXP-F13 SIB online by pressing the SFC ONLINE/OFFLINE button.
- Verify that the RxPWR LED for that fiber-optic array switching plane port is steadily lit green.
- If the RxPWR LED for any fiber-optic array switching plane port is lit steadily yellow or is not lit, take the TXP-F13 SIB offline again, remove the loopback connector, and clean the fiber-optic array switching plane ports and loopback connectors. Then reconnect the loopback connectors.
If the RxPWR LEDs for the fiber-optic array switching plane ports still fail to light steadily green, contact your customer support representative for additional instructions. - After you have finished testing the fiber-optic array switching plane port, remove a dust cover from the dust-free resealable plastic bag. To reinstall the dust cover on the loopback connector, align the dust cover with the loopback connector, and carefully press them together until they stop. The covers and the loopback connectors are keyed to ensure proper mating. Store the loopback connectors in the dust-free resealable plastic bag.

Packing the T1600 Router for Shipment
To pack the router for shipment:
- Retrieve the shipping crate and packing materials in which the router was originally shipped. If you do not have these materials, contact your Juniper Networks representative about approved packaging materials.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- On the console or other management device connected to the master Routing Engine, enter CLI operational mode. To shut down the router software:
user@host> request system halt
(If two Routing Engines are installed, also issue the command on the backup Routing Engine.) Wait until a message appears on the console confirming that the operating system has halted.
The command shuts down the Routing Engine cleanly, so its state information is preserved. For more information about the command, see request system halt.

NOTE: The SIB might continue forwarding traffic for approximately 5 minutes after the request system halt command has been issued.
- For all power supplies, shut down power to the router by pressing the circuit breakers to the off (O) position, or the power switch to the standby position.
- Disconnect power from the router. For instructions, see:
- Removing a T1600 DC Power Supply Cable From a Three-Input 240-A DC Power Supply or Four-Input 240-A DC Power Supply on page 410
- Removing a T1600 Three-Phase Delta AC Power Supply Cord on page 433

- Remove all Field Replaceable Units (FRUs) from the router.
- Remove the router from the rack:
- If you are using a mechanical lift, place the lift platform under the router, unscrew and remove the mounting screws from the rack, and move the router to the shipping crate.
- If you are not using a mechanical lift and the router weight is fully supported by a shelf or another router, unscrew and remove the mounting screws from the rack. Four people can then lift the router and move it to the shipping crate.
- If you are not using a mechanical lift and the router weight is not fully supported by a shelf or another router, four people should grasp the router while a fifth person unscrews and removes the mounting screws from the rack. The four lifters can then move the router to the shipping crate.
- Place the router in the shipping crate or onto the pallet. If on a pallet, bolt the router to the pallet.
- Cover the router with an ESD bag and place the packing foam on top of and around the router.
- Replace the accessory box on top of the packing foam.
- Securely tape the box closed or place the crate cover over the router.
- Write the RMA number on the exterior of the box to ensure proper tracking.

T1600 Preventing Electrostatic Discharge Damage
Many router hardware components are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge (ESD) damage, which can cause intermittent or complete component failures:
- Always use an ESD wrist strap or ankle strap, and make sure that it is in direct contact with your skin.

CAUTION: For safety, periodically check the resistance value of the ESD strap. The measurement should be in the range of 1 to 10 Mohms.
- When handling any component that has been removed from the chassis, verify that the equipment end of your ESD strap is attached to one of the ESD points on the chassis, which are shown in Figure 279 on page 553 and Figure 280 on page 554.
- Avoid contact between the component and your clothing. ESD voltages emitted from clothing can still damage components.
- When removing or installing a component, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an electrostatic bag (see Figure 281 on page 554). If you are returning a component, place it in an electrostatic bag before packing it.

Fire Safety Requirements for Juniper Networks Devices
- General Fire Safety Requirements on page 557
• Fire Suppression on page 557
• Fire Suppression Equipment on page 557
General Fire Safety Requirements
In the event of a fire emergency involving network devices, the safety of people is the primary concern. Establish procedures for protecting people in a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.
In addition, establish procedures to protect your equipment in a fire emergency. Juniper Networks products should be installed in an environment suitable for electronic equipment. We recommend that fire suppression equipment be available in the event of a fire in the vicinity of the equipment, and that you observe all local fire, safety, and electrical codes and ordinances when installing and operating your equipment.
Fire Suppression
In the event of an electrical hazard or an electrical fire, first turn power off to the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive fire retardants, to extinguish the fire.
Fire Suppression Equipment
Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide (CO_2) and Halotron, are most effective for suppressing electrical fires. Type C fire extinguishers displace the oxygen from the point of combustion to eliminate the fire. For extinguishing fire on or around equipment that draws air from the environment for cooling, use this type of inert oxygen displacement extinguisher instead of an extinguisher that leave residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers) near Juniper Networks devices. The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and difficult to clean.
In addition, in minute amounts of moisture, monoammonium phosphate can become highly corrosive and corrodes most metals.
Any equipment in a room in which a chemical fire extinguisher has been discharged is subject to premature failure and unreliable operation. The equipment is considered to be irreparably damaged.

NOTE: To keep warranties effective, donotuseadrychemical fire extinguisher to control a fire at or near a Juniper Networks device. If a dry chemical fire extinguisher is used, the unit is no longer eligible for coverage under a service agreement.
We recommend that you dispose of any irreparably damaged equipment in an environmentally responsible manner.

T1600 Chassis Lifting Guidelines
- Before moving the router, follow the guidelines in the site preparation checklist to verify that the intended site meets the specified power, environmental, and clearance requirements.
- Do not attempt to lift a fully configured router by yourself. Using a mechanical lift to maneuver the router into a rack is recommended. If a lift cannot be used, a minimum of four people is required to lift the router, and you must remove components from the chassis before lifting.
- Before lifting or moving the router, disconnect all external cables.
- As when lifting any heavy object, lift most of the weight with your legs rather than your back. Keep your knees bent and your back relatively straight and avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.

Related Documentation
DC Power Electrical Safety Warnings for Juniper Networks Devices on page 581.
T1600 DC Power Electrical Safety Guidelines
The following electrical safety guidelines apply to a DC-powered router:
- Be sure to connect the ground wire or conduit to a solid office (earth) ground. A closed loop ring is recommended for terminating the ground conductor at the ground stud.
- A DC-powered router is equipped with a DC terminal block that is rated for the power requirements of a maximally configured router.
To supply sufficient power, terminate the DC input wiring on a facility DC source capable of supplying at least 67 A @ -48 VDC per input for the three-input 240-A DC power supply, 48 A @ -48 VDC per input for the four-input 240-A DC power supply, or 56 A @ -48 VDC per input for the six-input DC power supply.
- Incorporate an easily accessible disconnect device into the facility wiring. In the United States and Canada, the -48 VDC facility should be equipped with a circuit breaker rated a minimum of 125% of the power provisioned for the input in accordance with the National Electrical Code in the US and the Canadian Electrical Code in Canada.

WARNING: For the six-input DC powersupply, failure to providetherequired circuit breaker or current-limiting fuse for each DC power cable can cause injury or damage to equipment.
For the six-input DC power supply, each 48 VDC facility DC source input power cable must be equipped with a current-limiting fuse or circuit breaker external to the Juniper Networks equipment rated at 80 A (-48 VDC) maximum. The voltage rating of the facility DC source circuit breaker must be 80 V minimum. We recommend an 80 A circuit breaker or current-limiting fuse rated for each 60 A DC power cable.
We recommend that the 48 VDC facility DC source be equipped with a circuit breaker rated at 80 A (-48 VDC) minimum for the three-input 240-A DC power supply or 60 A (-48 VDC) minimum for the four-input 240-A power supply, or as required by local code.
- Run two wires from the circuit breaker box to a source of 48 VDC. Use appropriate gauge wire to handle up to 80 A for a three-input 240-A DC power supply or 60 A for a four-input 240-A power supply.
- A DC-powered router that is equipped with a DC terminal block is intended only for installation in a restricted access location. In the United States, a restricted access area is one in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code ANSI/NFPA 70.

NOTE: Primary overcurrent protection is provided by the building circuit breaker. This breaker should protect against excess currents, short circuits, and earth faults in accordance with NEC ANSI/NFPA70.
- Ensure that the polarity of the DC input wiring is correct. Under certain conditions, connections with reversed polarity might trip the primary circuit breaker or damage the equipment.
- For personal safety, connect the green and yellow wire to safety (earth) ground at both the router and the supply side of the DC wiring.
- The marked input voltage of -48 VDC for a DC-powered router is the nominal voltage associated with the battery circuit, and any higher voltages are only to be associated with float voltages for the charging function.
- Because the router is a positive ground system, you must connect the positive lead to the terminal labeled RTN, the negative lead to the terminal labeled -48V, and the earth ground to the chassis grounding points.

• Electromagnetic Compatibility on page 585
Distance Limitations for Signaling
Improperly installed wires can emit radio interference. In addition, the potential for damage from lightning strikes increases if wires exceed recommended distances or if wires pass between buildings. The electromagnetic pulse (EMP) caused by lightning can damage unshielded conductors and destroy electronic devices. If your site has previously experienced such problems, you might want to consult experts in electrical surge suppression and shielding.
Radio Frequency Interference
You can reduce or eliminate the emission of radio frequency interference (RFI) from your site wiring by using twisted-pair cable with a good distribution of grounding conductors. If you must exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable.
Electromagnetic Compatibility
If your site is susceptible to problems with electromagnetic compatibility (EMC), particularly from lightning or radio transmitters, you might want to seek expert advice. Strong sources of electromagnetic interference (EMI) can destroy the signal drivers and receivers in the network device and conduct power surges over the lines into the equipment, resulting in an electrical hazard. It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.

CAUTION: To comply with intrabuilding lightning and surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends.

WARNING: The intrabuilding port(s) of the equipment or subassembly is suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type4portsas described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
