T320 Router Description
The T320 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).
Application-specific integrated circuits (ASICs) are a definitive part of the router design; these ASICs enable the router to achieve data forwarding rates that match current fiber-optic capacity.
The router accommodates up to eight Flexible PIC Concentrators (FPCs), which can each be configured with a variety of network media types—altogether providing up to 64 Gigabit Ethernet, 64 SONET/SDH OC-48/STM-16, or 16 SONET/SDH OC-192/STM-64 ports for the router.
The router's maximum aggregate throughput is 160 Gbps, full duplex. The router can forward traffic at high-performance rates for any combination of PICs that does not exceed 20 Gbps on a single FPC3. Any combination exceeding 20 Gbps is supported, but constitutes oversubscription. For information about the FPC types, see "T320 FPCs Supported" on page 63.
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 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.

T320 Component Redundancy
The T320 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 router has three SIBs. Each Type 1 FPC and Type 2 FPC has a dedicated ASIC with five high-speed links that connect to the SIBs (one link per SIB). A Type 3 FPC has two dedicated ASICs, and each ASIC has five high-speed links that connect to the SIBs (a total of 10 links). One of the three SIBs—usually SIB0—acts as a backup to the remaining two SIBs. In the event of a SIB failure, the backup SIB becomes active and traffic forwarding continues without any degradation. When the failed SIB is replaced, it becomes the new backup.
- 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.
- SONET Clock Generators (SCGs)—The router has a standard configuration of one SCG, but 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.
- 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.
- 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.

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 1 on page 5 shows the relationship between the Routing Engine and the Packet Forwarding Engines.

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 2 on page 6). 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.

D --> E["Packets out"]
F["Forwarding table updates"] --> C
G["Routing protocol packets from network"] --> B
H["Packets in"] --> C
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 7
• Data Flow on page 7
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 3 on page 8):

- 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.

T320 Chassis Description
The T320 Core Router chassis is a rigid sheet metal structure that houses all the other router components (see Figure 4 on page 14 and Figure 5 on page 15). The chassis measures 25.13 in. (63.82 cm) high, 31.4 in. (79.8 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 4 on page 14 and Figure 5 on page 15):
- A pairs of center-mounting metal brackets for center-mounting the chassis in an open-frame rack.
- Front-mounting flanges for front-mounting in an open-frame rack, or for mounting in a four-post rack or cabinet.
- 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.
WARNING: Before removing or installing any components of a functioning router, attach an ESD strap to one of the two ESD points on the chassis and attach the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the router and its components.

T320 Midplane Description
The T320 Core Router midplane is located in the center of the chassis and forms the rear of the FPC card cage (see Figure 6 on page 16). The FPCs install into the midplane from the front of the chassis, and the SIBs, Routing Engines, 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.
- Power distribution—The router power supplies are connected to the midplane, which distributes power to all the router components.
- Signal path—The midplane provides the signal path to the FPCs, SIBs, Routing Engines, control boards, and other system components for monitoring and control of the system.

T320 Cable Management System Description
The cable management system (see Figure 8 on page 18) 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 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.

T320 Craft Interface Alarm LEDs and ACO/LT Button
Two large alarm LEDs are located at the upper left of the craft interface (see Figure 10 on page 21). 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), as described in "T320 Alarm Relay Contacts" on page 18. The LCD on the craft interface reports the cause of the alarm, as described in "T320 Craft Interface LCD and Navigation Buttons" on page 22.
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.

T320 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.

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 the SIBs). The T320 router supports the following types of rear fan trays:
- The standard rear fan tray with five blowers (EOL) is supported by Junos OS 5.4 and later. It has no label and is not interchangeable with the standard front fan trays.
- The quiet rear fan tray, labeled REAR FANTRAY FAN-R-S and supported by Junos OS 11.1 and later,, contains eight fans and is not interchangeable with the quiet front fan trays.
- One upper front fan tray and one lower front fan tray that cool the components installed in the front card cage (the FPCs, PICs, CIP, and midplane). The T320 router supports the following front fan trays:
- The upper and lower standard front fan trays, each of which contain six fans and have no labels. Both standard fan trays are interchangeable with each other.
• Each quiet front fan tray contains four fans, as indicated by the four fan icons on the faceplate.
NOTE: The quiet upper front fan tray and quiet lower front fan tray are not interchangeable with each other. In addition to the labels, the quiet upper fan tray also has an upward pointing arrow above the four fan icons on the faceplate.
The quiet upper front fan tray is labeled FAN-T-FTOP-S and UPPER FANTRAY (see Figure 14 on page 27).

T320 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. To operate, each host subsystem functions as a unit; the Routing Engine requires the corresponding control board, and vice versa.
NOTE: We recommend you install two host subsystems for redundant protection. If you install only one host subsystem, we recommend you install it in slot REO.
Each host subsystem has three LEDs that display its status. The host subsystem LEDs are located on the upper right of the craft interface. For more information about the host subsystem LEDs, see "T320 Craft Interface Host Subsystem LEDs" on page 23.
The host subsystem consists of the following components:
• One or two Routing Engines
• One or two control boards

T320 Control Board Description
This chassis supports up to two control boards. The Routing Engine requires an adjacent control board to provide control and monitoring functions for the router. These functions include determining Routing Engine mastership; controlling power and reset for the other router components; monitoring and controlling fan speed; and monitoring system status.
You can install up to two control boards in the router. Control boards install into the upper rear of the chassis in the slots labeled CBO 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 T320 router supports the control boards listed in Table 8 on page 30.
NOTE: If two control boards are installed, they must both be the same hardware model during normal operations. A mix of hardware model numbers is supported only during upgrade.

T320 Routing Engine Description
The Routing Engine runs the Junos OS. Software processes that run on the Routing Engine maintain the routing tables, manage the routing protocols used on the router, control the 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. 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 is hot-pluggable. Each Routing Engine requires a control board to be installed in the adjacent slot. RE0 installs below CB0, and RE1 installs above CB1. A Routing Engine does not power up without a control board present in the adjacent slot.
NOTE: The LEDs that report host module status (including Routing Engine status) are on the craft interface rather than the Routing Engine faceplate.
NOTE: For specific information about Routing Engine components (for example, the amount of DRAM), issue the show chassis routing-engine command.
NOTE: If two Routing Engines are installed, they must both be the same hardware model.

T320 Routing Engine Ports
The CIP has two sets of ports that you use to connect the Routing Engines to external management devices. From these management devices, you can use the CLI to configure the router (see Figure 21 on page 40).
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. 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 millions of packets per second (Mbps) connections. Two small LEDs on the left edge of the port indicate the connection in use—the yellow LED lights for a 10-Mbps connection and the green LED lights for a 100 millions of packets per second (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.

T320 FPC Function
FPCs house the PICs that connect the T320 Core Router to network media. The main function of an FPC is to connect the PICs installed in it to the other 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 FPC3s installed, the Packet Forwarding Engines can forward up to 385 million packets per second (Mpps) for all packet sizes. The maximum aggregate throughput rate for the router is 160 Gbps (full duplex).
FPCs are hot-removable and hot-insertable. When you remove or install an FPC, packet forwarding is not interrupted. 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 continues uninterrupted during this process.
T320 FPC Slots
Up to eight Flexible PIC Concentrators (FPCs) install vertically in the front of the T320 Core Router (see Figure 22 on page 58). The FPC slots are numbered left to right from FPC0 to FPC7. Each FPC has two connectors into which a PIC can be installed, allowing
up to two PICs per FPC. An FPC can be installed into any FPC slot on the router, regardless of which PICs it contains. 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.
Figure 22: FPC Installed in T320 Router Chassis

Technical line drawing of a server rack unit with internal panel layout (no text or symbols)T320 FPC Components
Each FPC consists of the following components:
- FPC card carrier.
- One Packet Forwarding Engine—Each Packet Forwarding Engine consists 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.
-
Processor Mezzanine Board (PMB), which includes a 300-MHz CPU, system controller, 256 MB of SDRAM, and two Fast Ethernet interfaces.
• Each FPC contains data memory that is managed by the Queuing and Memory Interface ASICs. -
Two LEDs, located on the craft interface above the FPC, that display the status of the FPC. For more information on the FPC LEDs, see "T320 Craft Interface FPC LEDs" on page 23.
- FPC online/offline button, located on the craft interface above the FPC (see Figure 23 on page 59.
Figure 23: FPC Online/Offline Button on the Craft Interface
T320 FPC Edges
Regardless of whether you are holding an FPC vertically or horizontally, this documentation uses the same terms for all four edges of the FPC (see Figure 24 on page 59):
- 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 24: FPC Edges
Identifying the T320 FPCs
Enhanced FPCs and Enhanced II FPCs are labeled. Check the label on the faceplate to identify the FPC. However, standard FPCs are not labeled. To determine the type of standard FPC, check the location of the installed PIC's online/offline button and how the PIC is secured to the FPC (Table 34 on page 61).
Type 1 and Type 2 PICs installed in a standard FPC look similar, because both have two captive screws to secure the PIC to the FPC. Therefore, you must check the location of the PIC online/offline button.
- The PIC online/offline buttons are located on the Type 1 FPC above the PICs (see Figure 28 on page 62). Type 1 PICs do not have an online/offline button on the PIC faceplate (Figure 25 on page 60).
- The PIC online/offline buttons are located directly on the Type 2 PIC faceplates (see Figure 26 on page 60), rather than on the Type 2 FPC faceplate.
Figure 26: Type 2 PICFigure 25: Type 1 PIC
Type 2 and Type 3 FPCs look similar, because both have the PIC online/offline buttons directly on the PIC faceplates. Therefore, you can distinguish between a Type 2 and Type 3 FPC by checking whether the installed PICs have a plastic ejector handle (Type 3) (see Figure 27 on page 61), or a captive screw (Type 2) (see Figure 26 on page 60), at the top of the PIC faceplate.

T320 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 two or four PICs into the slots in each FPC. PICs used in a Type 1 FPC or Type 2 FPC have captive screws at their upper and lower corners. Type 3 PICs have an upper ejector handle and a lower captive screw.
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.

T320 Power System Description
The T320 Core Router supports DC power only. The router is equipped with two redundant, load-sharing DC power supplies (see Figure 30 on page 77), located at the lower rear of the chassis in slots PEM0 and PEM1 (top to bottom). Each power supply has one input,
which has its own circuit breaker, and which requires a dedicated DC power source. The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the router components, depending on their voltage requirements.
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.
Power supplies are hot-removable and hot-insertable. Each power supply is cooled by its own internal cooling system.

One LED on each power supply faceplate indicated the status of the power supply. In addition, a power supply failure triggers the red alarm LED on the craft interface. Table 41 on page 78 describes the functions of the power supply LEDs.

Switch Fabric Components and Descriptions
• T320 Switch Interface Boards (SIBs) Description on page 79
• T320 SIB LEDs on page 80
T320 Switch Interface Boards (SIBs) Description
The Switch Interface Boards (SIBs) provide the switching function to the destination FPC (see Figure 31 on page 79). The SIBs create the switch fabric for the router, providing up to a total of 385 million packets per second (Mpps) of forwarding.
Three SIBs are installed in the T320 router. The SIBs are located at the center rear of the chassis in the slots labeled SIB0 through SIB2 (top to bottom).
SIB0 acts as a backup to SIB1 and SIB2. If a SIB in slots SIB1 or SIB2 fails or is removed, SIB0 becomes active. A slight degradation in performance might occur. When the SIB in slots SIB1 or SIB2 is replaced or reinstalled, it will become active again and SIB0 reverts to backup. The router will regain full forwarding capacity.
SIBs are hot-insertable and hot-removable.
Figure 31: T320 SIB
Each SIB consists of the following components:
- Switch Fabric ASICs.
• High-speed links (HSLs) to each FPC.
Each Type 1 FPC and Type 2 FPC has one dedicated ASIC with five high-speed links that connect to the three SIBs:
• One high-speed link connects to SIBO.
- Two high-speed links connect to SIB1
- Two high-speed links connect to SIB2.
Each Type 3 FPC has two dedicated ASICs with five high-speed links that connect to the three SIBs.
- Three LEDs located on the SIB faceplate that display the status of the SIB."T320 SIB LEDs" on page 80 describes the functions of the SIB LEDs.
- SIB online/offline button, located on the SIB faceplate.

T320 Rack Requirements
The T320 Core Router can be installed many types of racks, including four-post racks or cabinets and open-frame racks. An example of an open-frame rack appears in Figure 32 on page 85.
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 is designed to 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: 25.13 in. (63.82 cm) high, 31.4 in. (79.8 cm) deep, and 17.43 in. (44.3 cm) wide. The outer edges of the front-mounting flanges and center-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 that are specified in "T320 Clearance Requirements for Airflow and Hardware Maintenance" on page 85.
The chassis height of 25.13 in. (63.82 cm) is approximately 14.4 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 three routers in a rack that has at least 44 U (77 in. or 1.96 m) of usable vertical space.
The rack must be strong enough to support the weight of the fully configured router, up to approximately 370 lb (168 kg). If you stack three fully configured routers in one rack, it must be capable of supporting about 1110 lb (504 kg).

T320 Clearance Requirements for Airflow and Hardware Maintenance
When planning the installation site, you must allow sufficient clearance around the rack (see Figure 33 on page 86):
- For the cooling system to function properly, the airflow around the chassis must be unrestricted. Figure 13 on page 26 depicts the airflow in the router.
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) is required both in front of and behind the router. NEBS GR-63 recommends that you allow at least 30 in. (72.6 cm) in front of the rack.

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 94 and Supported Network Interface Standards by Transceiver for the ACX, M, MX, and T Series 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 93
- Attenuation and Dispersion in Fiber-Optic Cable on page 94
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 or Supported Network Inter 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 95
- Calculating Power Margin for Fiber-Optic Cable on page 95
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 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 50 on page 95 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 50: 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 dista 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 50 on page 95 to calculate link loss (LL) for a 2-km-long multimode link with a power budget3(18B:
• 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 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 50 on page 95 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.

Installing the T320 Mounting Hardware for an Open-Frame Rack
To prepare to mount the T320 Core Router into an open-frame rack, install the large mounting shelf on the rack. Install cage nuts, if needed. The small mounting shelf and the spacer bars are not needed.
For open-frame racks, center-mounting the chassis is preferable to front-mounting because the more even distribution of weight provides greater stability. You use the center-mounting brackets to center-mount the chassis in an open-frame rack; you use the front-mounting flanges to front-mount the chassis in an open-frame rack.
For an open-frame rack, Table 55 on page 107 specifies the holes in which you insert mounting screws (an X indicates a mounting hole location), and cage nuts if needed. The hole distances are relative to one of the standard U divisions on the rack. For reference the bottom of all mounting shelves is at 0.0015 in. (0.01 U) above a U division.

To install the large mounting shelf (see Figure 37 on page 108):
- Install cage nuts, if needed, in the mounting holes specified in Table 55 on page 107:
- • On the front side of the rack rails, install cage nuts for the chassis.
- On the rear side of the rack rails, install cage nuts for the large shelf.
- On the rear of each rack rail, partially insert a mounting screw into the highest hole specified for the large shelf in Table 55 on page 107.
- Install the large shelf on the rack. Hang the shelf over the mounting screws using the keyhole slots located near the top of the large shelf flanges.
- Partially insert screws into the open holes in the ears of the large shelf.
- Tighten all the screws completely.
- Remove the center-mounting brackets by loosening the screws at the top and bottom of each bracket.

Installing the T320 Chassis in the Rack Manually
CAUTION: If you are installing two routers in one rack, install the lower one first. Installing a router in the upper position in a rack or cabinet requires a lift.
CAUTION: Before front mounting the router in a rack, have a qualified technician verify that the rack is strong enough to support the router's weight and is adequately supported at the installation site.
CAUTION: Lifting the chassis and mounting it in a rack requires four people. The empty chassis weighs approximately 131.4 lb (59.6 kg).
To install the router in the rack (see Figure 51 on page 133):
- 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 "T320 Site Preparation Checklist Requirements" on page 83.
- Attach the installation handle by tightening the captive screws of the handle into the holes previously occupied by the captive screws of the power supplies (see Figure 50 on page 131). Tighten the screws, using a Phillips (+) screwdriver, number 2.

CAUTION: Do not lift the router using the craft interface, installation handle, or the handles on the sides of the chassis. Use these handles only to help position the router.
- With two people in the front and two people in the back, hold onto the bottom of the chassis and carefully lift it onto the mounting shelves.
WARNING: To prevent injury, keep your back straight and lift with your legs, not your back. Avoid twisting your body as you lift. Balance the load evenly and be sure that your footing is solid.
- 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 router onto the mounting shelves until the center-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.
-
Install the mounting screws:
-
Four-post rack or cabinet—Install a mounting screw through each of the holes in the spacer bars.
-
Open-frame rack—Install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom.
-
Loosen the captive screws on the installation handle completely, and remove the handle from the chassis.
-
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 PIC Cables to the T320 Router
To connect cable to the PICs (see Figure 59 on page 147, which shows a fiber-optic PIC):
- Have ready a length of the type of cable used by the PIC. For cable specifications, see the T320 Core Router Interface Module Reference.
- 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 afewinches 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 T320 Router
You connect DC power to the T320 router by attaching power cables from the DC power sources to the terminal studs on the power supply faceplates. To connect power to the router, you must provide DC power cables (the cable lugs are supplied with the router). For power cable specifications, see "T320 DC Power Cable Specifications" on page 89.
To connect the DC source power cables to the router for each power supply:
- 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.
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.
- 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.
- Verify that the source power cabling is correct, that the cables are not touching or blocking access to router components, and that they do not drape where people could trip on them.
- Switch the circuit breaker on the power supply faceplate to the off position (O).
- Remove the clear plastic cover protecting the terminal studs on the faceplate.
- Remove the nuts and washers from the terminal studs.
- 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 (see "Connect Power Cables to the T320 Power Supply" on page 231). Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.
a. Attach the positive (+) DC source power cable lugs to the RETURN (return) terminals.
b. Attach the negative (−) DC source power cable lugs to the -48V (input) terminals.
CAUTION: Each power supply must be connected to a dedicated DC power source.
- Loosen the captive screws on the cable restraint on the right edge of the power supply faceplate.
- Route the positive and negative DC power cables through the top and bottom of the cable restraint.
- Tighten the cable restraint captive screw to hold the power cables in place.
- Verify that the ground and power cabling are correct, that they 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 T320 Router
To power on the 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 source power cables are connected to the appropriate terminal: the positive (+) source cable to the return terminal (labeled RETURN) and the negative (−) source cable to the input terminal (labeled -48V).
- Verify that an external management device is connected to one of the Routing Engine ports on the CIP (AUXILIARY, CONSOLE, or ETHERNET). For more information about connecting management devices, see "Overview of Connecting the T320 Router to External Devices" on page 145.
- Turn on the power to the external management device.
- Switch the circuit breaker on one of the power supplies to the on position (J) and observe the LEDs on the power supply faceplate. If the power supply is correctly installed and is functioning properly, the DC OK LED lights steadily, and the CB ON LED blinks momentarily, then lights steadily.
NOTE: After powering off a power supply, wait at least 60 seconds before turning it back on. After powering on a power supply, wait at least 60 seconds before turning it off.
If the system is completely powered off when you power on the power supply, theRouting Engine boots as the powersupply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, see "Powering Off the T320 Router" on page 156.
After a powersupply is powered on, it can takeup to 60 seconds for status indicators—such as the output status LEDs on the power supply, the command display output, and messages on the LCD on the craft interface—to indicate that the powersupply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
- Repeat Step 5 for the remaining power supply.
NOTE: If any of the output status LEDs does not light steadily, repeat the installation and cabling procedures described in "Replacing a T320 DC PowerSupply" on page 229 and "Connecting DC Powerto the T320Router" on page 153.
- On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.

T320 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.
If the router contains a redundant host subsystem, the backup control board (), and the backup Routing Engine are hot-removable and hot-insertable. Before you replace a control board or Routing Engine, you must take the host subsystem offline.
Table 57 on page 166 lists the FRUs for the T320 Core Router.

Replacing a T320 SCG
The SCGs are hot-pluggable. If two SCGs are installed and both are functioning normally, SCG0 is the master and SCG1 is the backup. Removing the backup SCG does not affect
the functioning of the router. Taking the master SCG offline might result in a brief loss of SONET clock lock while the backup SCG becomes the master.
You can determine which SCG is functioning as the master in one of two ways:
- To display which SCG is functioning as the master: user@host> show chassis clocks
- Check the blue MASTER LED on the SCG faceplate. If this LED is on steadily, the SCG is functioning as the master.
To replace an SCG, perform the following procedures:
- Removing a T320 SCG on page 176
- Installing a T320 SCG on page 177
Removing a T320 SCG
The router can have one or two SCGs installed. The SCGs are located in the rear of the chassis, above the SIBs. Each SCG weighs approximately 1.9 lb (0.9 kg).
To remove an SCG (see Figure 69 on page 177):
- 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.
- Press the online/offline button on the SCG faceplate and hold it down until the OK LED goes out (about 5 seconds).
- Loosen the captive screws on the edges of the SCG faceplate.

- Replacing a DIMM Module in T320 Routing Engines on page 198
- Replacing a T320 Routing Engine on page 199
Taking the T320 Host Subsystem Offline
The host subsystem is taken offline and brought online as a unit. Before you replace a control board or Routing Engine, you must take the host subsystem offline.
Normally, if two host subsystems are installed in the router, REO functions as the master and REI functions as the backup. You can remove the backup host subsystem (or either of its components) without interrupting the functioning of the router. If you take the master host subsystem offline, the backup host subsystem becomes the master (the router might reboot, depending on your configuration). If the router has only one host subsystem, taking the host subsystem offline causes the router to shut down.
Table 59 on page 191 explains the effect of taking the host subsystem offline.

| 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.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, graceful restart, and nonstop activerouting, see the Junos OS High Availability Library for Routing Devices.
NOTE: The first supported release for graceful Routing Engine switchover and nonstop active routing on the T320 router is Junos OS Release 7.0 and Junos OS Release 8.4, respectively. Graceful restart software requirements are dependent on the routing protocols configured on the router. For the minimum software requirements for graceful restart, 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
- To halt the Routing Engine:
user@host> request system halt
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 SIBs might continue forwarding traffic for approximately five minutes after the request system halt command has been issued.
- On the console or other management device connected to the other Routing Engine, enter CLI operational mode and issue the following command.
user@host> request chassis cb offline slot n
n is 0 or 1 for the slot number of the host subsystem being taken offline.
- Verify that the control board is offline:
user@host> show chassis environment cb

Replacing Line Card Components
- Replacing a T320 FPC on page 215
- Replacing a T320 PIC on page 220
- Replacing T320 PIC Cables on page 225
Replacing a T320 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 T320 FPC on page 215
- Installing a T320 FPC on page 217
Removing a T320 FPC
The router holds up to eight FPCs, which are installed vertically in the front of the router. An empty FPC weighs approximately 14.8 lb (6.7 kg) and a fully configured FPC can weigh up to 19 lb (8.6 kg).
Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC blank panel weighs 6.3 lb (2.9 kg).
To remove an FPC (see Figure 103 on page 217):
- Have ready a replacement FPC or FPC blank panel and an antistatic mat for the FPC. Also have ready rubber safety caps for each PIC using an optical interface on the FPC that you are removing.
- 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 cables connected to each PIC on the FPC so that you can later reconnect the cables to the correct PICs.
- 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 CLI command:
user@host>request chassis fpc slot slot-numberoffline
For more information about the command, see show 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 the ends of fiber-optic cables or into the transceivers on the PIC faceplate. Single-mode fiber-optic cable and the PICs that use it (such as ATM and SONET/SDH interfaces) 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.
-
If you are removing a Type 2 or a 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 19 lb (8.6 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 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 necessary, remove each installed PIC from the FPC.
-
After you remove each PIC, immediately place it on an antistatic mat or in an electrostatic bag.
-
If you are not reinstalling a 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.

To install an FPC (see Figure 104 on page 219 and Figure 105 on page 220):
-
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see "Preventing Electrostatic Discharge Damage to a T320 Router" on page 308.
-
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 on installing a PIC, see "Installing a T320 PIC" on page 223.
- Locate the slot in the FPC card cage in which you plan to install the FPC.
- Lift the FPC into place and carefully align first the bottom, then the top of the FPC with the guides inside the card cage. 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 or edge connectors. They cannot support its weight.
- Slide the FPC all the way into the card cage until you feel resistance.
- Starting with the ejector handles on the FPC faceplate nearly horizontal, simultaneously turn both ejector handles clockwise to seat the FPC.
- 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 the ends of fiber-optic cables or into the transceivers on the PIC faceplate. Single-mode fiber-optic cable and the PICs that use it (such as ATM and SONET/SDH interfaces) 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 CLI command:
user@host>request chassis fpc slot slot-numberonline
For more information about the command, see request chassis fpc.
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 plc-status commands described in "Maintaining T320 FPCs" on page 255 and "Maintaining T320 PICs and PIC Cables" on page 260.

Removing a T320 PIC
PICs are hot-insertable and hot-removable. When you remove a PIC, the router continues to function, although the PIC interfaces being removed no longer function.
The PICs are located in the FPCs installed in the front of the router. A PIC weighs less than 2 lb (0.9 kg).
To remove a PIC (see Figure 106 on page 222):
- Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and 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.
- Use one of the following methods to take the PIC offline:
- Press and hold the online/offline button until the PIC LED goes out (about 5 seconds).
For a PIC installed in a Type 1 FPC, use a tool—such as a flat-blade screwdriver—to press the button slightly beneath the faceplate of the PIC. For a PIC installed in a Type 2 FPC or Type 3 FPC, use a narrow-ended tool that fits inside the opening that leads to the button.
- Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
For more information about the command, see request chassis pic.
- Label the cables connected to the PIC so that you can later reconnect each cable to the correct PIC.
- Disconnect the cables from the PIC. If the PIC uses fiber-optic cable, immediately cover each transceiver and the end of each 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.
-
Unseat the PIC:
-
Type 1 or Type 2 PIC—Loosen the captive screws at the top and bottom of the PIC faceplate.
- Type 3 PIC—Loosen the captive screw at the bottom of the PIC faceplate, then twist the ejector handle at the top of the faceplate and counterclockwise to unseat the PIC.
-
Type 4 PIC—Twist the ejector handle at the bottom of the PIC faceplate, then twist the ejector handle at the top of the faceplate and counterclockwise to unseat the PIC.
-
Slide the PIC out of the FPC card carrier, and place it in the electrostatic bag or on the antistatic mat.
- If you are not reinstalling a PIC into the emptied PIC slot within a short time, install a blank PIC panel over the slot to maintain proper airflow in the FPC card cage.

Replacing Power System Components
- Replacing a T320 DC Power Supply on page 229
- Replacing a T320 DC Power Supply Cable on page 234
Replacing a T320 DC Power Supply
The router has two redundant, load-sharing DC power supplies. Each power supply is hot-insertable and hot-removable. When one power supply is powered down or removed, the other power supply automatically assumes the entire electrical load for the router.
- Removing a T320 DC Power Supply on page 229
- Installing a T320 DC Power Supply on page 231
Removing a T320 DC Power Supply
The power supplies are located at the rear of the chassis below the SIBs. Each power supply weighs approximately 12 lb (5.4 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.
NOTE: After powering off a power supply, wait at least 60 seconds before turning it back on.
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.
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see "Preventing Electrostatic Discharge Damage to a T320 Router" on page 308.
- Switch the circuit breaker on the power supply faceplate to the off position (0).
- Remove the clear plastic cover protecting the terminal studs on the faceplate.
- Remove the nuts and washers from the terminal studs (see Figure 109 on page 230). (Use a 7/16-in. nut driver or pliers.)
Figure 109: Disconnecting Power Cables from the DC Power Supply
- Remove the cable lugs from the terminal studs.
- Loosen the captive screws on the cable restraint 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 110 on page 231).
WARNING: Do not touch the power connectors on the rear of the power supply (see Figure 111 on page 231). 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 power supply weighs approximately 12 lb (5.4 kg). Be prepared to support the full weight of the power supply as you remove it from the router.

- Switch the circuit breaker on the power supply faceplate to the off position (O).
- Using both hands, slide the power supply into the chassis until you feel resistance.
- Twist the ejector handles at the upper corners of the power supply faceplate clockwise until they stop.
- Tighten the captive screws at the lower corners of the power supply faceplate to secure the power supply in the chassis.
- Remove the clear plastic cover protecting the terminal studs on the faceplate.
- Remove the nuts and washers from the terminal studs.
- Attach the lugs on the DC source power cables to the terminal studs.
a. Attach the positive (+) DC source power cable lugs to the RETURN (return) terminals.
b. Attach the negative (−) DC source power cable lugs to the -48V (input) terminals.
Secure the cable lugs to the terminal studs, first with the washers, then with the nuts. Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.
- Verify that the power cables are not touching or in the way of any other components.
- Loosen the captive screws on the cable restraint on the right edge of the power supply faceplate.
- Route the positive and negative DC power cables through the top and bottom of each cable restraint.
- Tighten the cable restraint captive screws to hold the power cables in place.
- Verify that the ground and power cabling are correct, that they 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.
-
Switch on the external circuit breakers to provide voltage to the DC power source cable leads.
-
Switch the circuit breaker on the power supply to the on position (I) and observe the LEDs on the power supply faceplate. If the power supply is correctly installed and is functioning properly, the DC OK LED lights steadily, and the CB ON LED blinks momentarily, then lights steadily.
NOTE: After powering off a power supply, wait at least 60 seconds before turning it back on. After powering on a power supply, wait at least 60 seconds before turning it off.
If the system is completely powered off when you power on the power supply, the RoutingEngine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, see "Powering Off the T320 Router" on page 156.
After a powersupply is powered on, it can takeup to 60 seconds for status indicators—such as the output status LEDs on the power supply, the command display output, and messages on the LCD on the craft interface—toindicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

Removing a T320 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 116: Small Form-Factor Pluggable (SFP)
NOTE: This procedure applies to both SFP and SFP+ transceivers.
To remove an SFP transceiver (see Figure 116 on page 240):
- 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 T320 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.

Maintaining the T320 Air Filters
Purpose For optimum cooling, verify the condition of the filters.
Action On a regular basis:
Check the air filters regularly for dust and debris. Replace the filter elements as needed. The filter elements degrade over time, so the filter elements in use, as well as spares, should be replaced every 6 months. For procedures to replace the air filters, see “Replacing a T320 Air Filter” on page 181.
Spare filter elements should be used 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.

Holding T320 FPCs
CAUTION: Many components on the FPC are fragile. Failure to handle FPCs as specified in this document can cause irreparable damage.
NOTE: An FPC configured with PICs installed can weigh as much as 29 lb (13.2 kg). Be prepared to accept the full weight of the FPC as you lift it.
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 119 on page 257).
Figure 119: Do Not Grasp the Connector Edge
- Do not carry the FPC by the faceplate with only one hand (see Figure 120 on page 258).

natural_image
Technical line drawing of a mechanical component with a circular crosshair overlay (no text or symbols)You hold an FPC vertically when installing it into the chassis or an equipment rack. To hold an FPC vertically (see Figure 122 on page 259):
- 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 122: Holding an FPC Vertically
Storing T320 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.

Maintaining T320 PICs and PIC Cables
Purpose For optimum router performance, verify the condition of the PICs and PIC cables.
Action On a regular basis:
- 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 T320 Power Supplies
Purpose For optimum router performance, verify the condition of the power supplies.
Action On a regular basis:
- To check the status of the power supplies, issue the show chassis environment pem command. The output is similar to the following:
user@host> show chassis environment pem
PEM 0 status:
| State | Online |
| Temperature | OK |
| DC input: | OK |
- Check that the voltages in each load zone are equal.
NOTE: The current sharing between PEMs relies on equal voltages at the input terminals of the PEMs. The T320 Internet Router system power is divided into two load zones. (INPUT 0 of PEM0 should be matched with INPUT 0 of PEM1; INPUT 1 of PEM0 should be matched with INPUT 1 of PEM1)
Therefore, those two PEMs voltages should be equal for current sharing. 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 "T320 Power System Electrical Specifications" on page 90. See Figure 35 on page 92 for a typical DC source cabling arrangement.
- Make sure that the power and grounding cables are arranged so that they do not obstruct access to other router components.
- Routinely check the LEDs on the power supply faceplates. If the CB ON LEDs are lit, the power supplies are functioning normally. For more information about the power supply LEDs, see “T320 Power System Description” on page 77.
- 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 CLI command:
user@host> show chassis alarms
•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 there is no moisture accumulating near the router. To review grounding and site wiring requirements for the router, see “T320 Chassis Grounding Cable and Lug Specifications” on page 87 and “Site Electrical Wiring Guidelines for Juniper Networks Devices” on page 337.
- Regularly inspect the air filter on each power supply for dust and debris, and replace the filter element every 6 months. To replace a power supply filter element:
- Grasp the filter cover on the power supply faceplate and pull it straight off the power supply.
- Remove the filter element.
- Install a new filter element.
- Press the filter cover straight onto the power supply faceplate until all four sides click into place.

Overview of Troubleshooting Resources for the T320 Router
To troubleshoot a 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 router.
- LCD—When a red or yellow alarm occurs, the cause of the alarm messages is displayed on the craft interface LCD.
- 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. Use the CLI to display more information about alarms. 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 the 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.

Troubleshooting the T320 Cooling System
Problem Description: During normal operation:
•Fans in both front and rear fan trays function at less than 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.
NOTE: If the router temperature exceeds the acceptable maximum, the control board turns off the power supplies.
The following alarms and LEDs indicate a problem when:
• A fan fails (red alarm).
•One of the fan trays is removed (yellow alarm).
•The router temperature exceeds the “temperature warm” threshold (yellow alarm).
•The temperature of the router exceeds the maximum (“temperature hot”) threshold (red alarm and automatic shutdown of the power supplies).
Solution To troubleshoot the fans, follow these guidelines:
- If the red alarm LED on the craft interface lights, find the source of the problem by looking at the display on the craft interface. The number of alarm conditions, as well as the source of each alarm, appears on the screen.
- 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
- 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 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.
- If all power supplies have failed, the system temperature might have exceeded the threshold, causing the system to shut down.
- If the display on the craft interface 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, as described in "Replacing a T320 Fan Tray" on page 186.

Troubleshooting the T320 Power System
Problem Description: The power system is not functioning normally.
Solution - Check the OUTPUT OK LED on each power supply faceplate (or the corresponding POWER OK LED on the craft interface). If this LED is on, the power source is good and the power supply is functional. - Check the display on the craft interface. The Junos OS constantly updates the screen with status information for each component. For more information about the display, see "T320 Craft Interface Description" on page 20.
NOTE: On the display and in the CLI, the power supplies are referred to as PEM0 through PEM3, from top to bottom.
If a power supply is not functioning normally, perform the following steps to diagnose and correct the problem:
- If the OUTPUT OK power supply LED is off, check the red alarm LED on the craft interface. The Junos OS monitors the system temperature, and if it exceeds a certain limit, the software triggers a red alarm, a condition that shuts down the power supplies.
- If a red alarm condition occurs, check the display on the craft interface to determine the source of the problem.
NOTE: If the system temperature exceeds the threshold, the Junos OS shuts down all power supplies so that no status is displayed.
The Junos OS also can shut down one of the power supplies for other reasons. In this case, the remaining power supply assumes the load, and you can still view the system status through the CLI or display.
- If the OUTPUT OK power supply LED is off and no red alarm condition exists, check that the circuit breaker is switched to the on position (1).
- Verify that the source circuit breaker has the proper current rating. Each power supply must be connected to a separate source circuit breaker.
- Verify that the DC power cables from the power source to the router are not damaged. If the insulation is cracked or broken, immediately replace the cord or cable.
- Connect the power supply to a different power source with a new DC power cable. If the power supply OUTPUT OK LED still does not light, the power supply is the source of the problem. Replace the power supply with a spare, as described in "Replacing a T320 DC Power Supply" on page 229.
- If the OUTPUT OK LED on the installed spare lights, the replaced power supply is faulty. Return it for replacement, as described in “Returning a Hardware Component to Juniper Networks, Inc.” on page 297.
- If you cannot determine the cause of the problem or need additional assistance, see "Contacting Customer Support" on page 287.

Preventing Electrostatic Discharge Damage to a T320 Router
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 through 10 Mohms.
- When handling any component that is removed from the chassis, make sure the equipment end of your ESD strap is attached to one of the ESD points on the chassis.
- 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 134 on page 308). If you are returning a component, place it in an electrostatic bag before packing it.

• Fire Suppression on page 309
• Fire Suppression Equipment on page 309
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.

Chassis Lifting Guidelines
The weight of a fully configured T320 chassis is up to 370 lb (168 kg). Observe the following guidelines for lifting and moving the router:
- 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 mechanical lift cannot be used, a minimum of three people are 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.

Installation Safety Warnings for Juniper Networks Devices
Observe the following warnings before and during hardware equipment installation:
• Intra-Building Ports Warning on page 312
• Installation Instructions Warning on page 312
- Rack-Mounting Requirements and Warnings on page 313
- Ramp Warning on page 316
Intra-Building Ports Warning
WARNING: The intra-building ports of the equipment or subassembly are suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building ports 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 intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089) 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.
Installation Instructions Warning
WARNING: Read the installation instructions before you connect the hardware equipment to a power source.
Rack-Mounting Requirements and Warnings
Ensure that the equipment rack into which the chassis is installed is evenly and securely supported, to avoid the hazardous condition that could result from uneven mechanical loading.
WARNING: To prevent bodily injury when mounting or servicing the chassis in a rack, take the following precautions to ensure that the system remains stable. The following directives help maintain your safety:
- The chassis must be installed into a rack that is secured to the building structure.
- When mounting the chassis in a partially filled rack, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack.
- If the rack is provided with stabilizing devices, install the stabilizers before mounting the chassis in the rack or servicing the hardware equipment.
WARNING: When installing the hardware equipment, do not use a ramp inclined at more than 10 degrees.

- Multiple Power Supplies Disconnection Warning on page 332
• Power Disconnection Warning on page 333
Grounded Equipment Warning
WARNING: The network device is intended to be grounded. Ensure that the network device is connected to earth ground during normal use.
Grounding Requirements and Warning
An insulated grounding conductor that is identical in size to the grounded and ungrounded branch circuit supply conductors, but is identifiable by green and yellow stripes, is installed as part of the branch circuit that supplies the unit. The grounding conductor is a separately derived system at the supply transformer or motor generator set.
WARNING: When installing the network device, you must always make the ground connection first and disconnect it last.
Midplane Energy Hazard Warning
WARNING: High levelsofelectrical energy are distributed acrosssthemidplane. Be careful not to contact the midplane connectors, or any component connected to the midplane, with any metallic object while servicing components.
Multiple Power Supplies Disconnection Warning
WARNING: The network device has more than one powersupply connection. All connections must be removed completely to remove power from the unit completely.
Power Disconnection Warning
WARNING: Before working on the chassis or near power supplies, switch off the power at the DC circuit breaker.

DC Power Electrical Safety Warnings for Juniper Networks Devices
When working with DC-powered equipment, observe the following warnings:
• DC Power Copper Conductors Warning on page 334
• DC Power Disconnection Warning on page 334
• DC Power Wiring Terminations Warning on page 336
DC Power Copper Conductors Warning
WARNING: Use copper conductors only.
DC Power Disconnection Warning
WARNING: Before performing any procedures on powersupplies, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position.
DC Power Wiring Terminations Warning
WARNING: When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor.

•General Electrical Safety Warnings for Juniper Networks Devices on page 330
Site Electrical Wiring Guidelines for Juniper Networks Devices
• Distance Limitations for Signaling on page 337
• Radio Frequency Interference on page 337
• Electromagnetic Compatibility on page 337
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,Issue4) 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.
