Documentation and Release Notes

To obtain the most current version of all Juniper Networksal documentation, see the product documentation page on the Juniper Networks website at https://www.juniper.net/documentation/.

If the information in the latest release notes differs from the information in the documentation, follow the product Release Notes.

Juniper Networks Books publishes books by Juniper Networks engineers and subject matter experts. These books go beyond the technical documentation to explore the nuances of network architecture, deployment, and administration. The current list can be viewed at https://www.juniper.net/books.

Using the Examples in This Manual

If you want to use the examples in this manual, you can use the load merge or the load merge relative command. These commands cause the software to merge the incoming configuration into the current candidate configuration. The example does not become active until you commit the candidate configuration.

If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a full example. In this case, use the load merge command.

If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command. These procedures are described in the following sections.

Merging a Full Example

To merge a full example, follow these steps:

1. From the HTML or PDF version of the manual, copy a configuration example into a text file, save the file with a name, and copy the file to a directory on your routing platform.

For example, copy the following configuration to a file and name the file ex-script.conf. Copy the ex-script.conf file to the /var/tmp directory on your routing platform.

system {
    scripts {
    commit {
    file ex-script.xsl;
    }
    }
}
interfaces {
    fxp0 {
    disable;
    unit 0 {
    family inet {
    address 10.0.0.1/24;
    }
    }
    }
} 

1. Merge the contents of the file into your routing platform configuration by issuing the load merge configuration mode command:

[edit]
user@host# load merge /var/tmp/ex-script.conf
load complete 

Merging a Snippet

To merge a snippet, follow these steps:

1. From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the file with a name, and copy the file to a directory on your routing platform For example, copy the following snippet to a file and name the file ex-script-snippet.conf.

ACX6360 Universal Metro Router Description

The Juniper Networks ACX6360 Universal Metro Router is part of Juniper Networks converged and automated Metro Fabric solution. It bridges the complexity between packet optical transport and the IP/MPLS networking layer by collapsing both domains into a seamless, multilayer solution with a single-pane-of-glass view.

• Benefits of the ACX6360 Router on page 19
• System Overview on page 20
- Port Panel on page 21
• Management Panel on page 22

Benefits of the ACX6360 Router

• IP-optical convergence—The ACX6360 provides full IP/MPLS stack and secure packet optical transport convergence. It gives a single, multilayer management view of metro, DCI, and DAA deployments.

• High port density and performance transport—The ACX6360 contains both, 100-Gbps (QSFP28) pluggable interfaces and 200-Gbps CFP2-DCO coherent DWDM pluggable interfaces, which support 100-Gbps QPSK and 200-Gbps 8QAM, and 16QAM modulation options.

• Industry compliant security—MACsec packet transport and IEEE 802.1AE encryption, 802.1X authentication, and 256AES MACsec encryption are supported on all of the ACX6360's ports.

• Flexible design—The ACX6360 can perform as either a transponder or a router. Supplying either muxponder-like pass-through connection of client interface traffic to line optical interfaces or IP/MPLS routing services from any interface and to any interface.
• Disaggregated and open-line system—The Acx6360 optimizes open-line system performance when combined with disaggregated control design. This enables flexible updates with service continuity and the freedom to deploy best-of-breed transponder solutions.
• Cloudgrade performance—The ACX6360 supports modern automation and telemetry tools. With Junos OS, proNX Optical Director, and NorthStar Controller it can perform multilayer traffic engineering and intent-based operations and management tasks.

System Overview

The ACX6360 router is a fixed-configuration router that supports 10-Gbps, 40-Gbps, 100-Gbps, and 200-Gbps port speeds in a single 1U stackable platform.

• Control operations are performed by the Routing Engine, which runs the Juniper Networks Junos operating system (Junos OS). The Routing Engine handles routing protocols, traffic engineering, policy, policing, monitoring, and configuration management. Junos OS is installed on the ACX6360 router's internal 2 x 50-gigabyte (GB) M.2 SATA solid-state drives (SSDs). The Routing Engine is enhanced by a 1.6-GHz 4 core Intel CPU and 24 GB of SDRAM.
• Forwarding operations are performed by the Packet Forwarding Engines, which uses Juniper Networks Express-based silicon. The custom ASICs enable the ACX6360 to provide up to 3.6 Tbps of throughput and 2 Bpps of forwarding capacity.

You can choose between two platform configuration modes:

• Label-switched Router Mode (ACX6360-OR), which passes traffic from any interface to any interface, enabling statistical multiplexing advantages.
• Muxponder-like Transponder Mode (ACX6360-OX), which maps client interface to line optical ports.

NOTE: The mode of the device (Router Mode or Transponder Mode) is determined by the software package installed on your device. For information on changing the operational mode of the ACX6360, see "Changing Operational Modes on the ACX6360" on page 82. To better understand how the Transponder Mode operates or to troubleshoot issues with the Transponder Mode configuration, see "Transponder Mode on the ACX6360" on page 83.

TIP: For information about features supported on ACX Series routers, see Feature Explorer.

Port Panel

The port panel of the ACX6360 contains 28 network ports, port LEDs, console and management ports, and system status LEDs. Figure 1 on page 21 shows the ACX6360 port panel.

Figure 1: ACX6360 Port Panel and Management Panel

The 20 network ports on the left side of the port panel are QSFP28 ports.

Table 3 on page 21 describes the maximum number of ports for each interface type supported by the QSFP28 ports.

NOTE: When the ACX6360 is configured as a router, the 20 QSFP28 ports can be configured as 10 Gbps, 40 Gbps, or 100 Gbps. When the ACX6360 is be used as a transponder, the first 16 QSFP28 ports (0 to 15) are configured as 100 Gbps. The remaining 4 ports (16 to 19) cannot be used.

Table 3: QSFP28 Ports: Maximum Supported Ports at Each Interface Speed

Interface Type	Maximum Supported Ports
10-Gigabit Ethernet	80
40-Gigabit Ethernet	20
100-Gigabit Ethernet	20

The 8 network ports on the right side of the port panel are CFP2 ports. Table 4 on page 22 describes the maximum number of ports for each interface type supported by the CFP2 ports.

Table 4: CFP2 Ports: Maximum Supported Ports

	Maximum Supported PortsInterface Type
	8200-Gigabit Ethernet

You manage the ACX6360 by using the Junos OS CLI, which is accessible through the console and out-of-band management ports on the management panel. In addition, the management panel has system status LEDs that alert you to minor or major alarms or other issues with the router, external clock synchronization ports, and a USB port to support software installation and recovery.

Management Panel

The management panel of the ACX6360 is located on the FRU side of the device. It contains management ports, the fan modules, and power supplies for the ACX6360. Figure 2 on page 22 shows the ACX6360 management panel.

ACX6360 Component Redundancy

The following hardware components provide redundancy on an ACX6360:

- Power supplies—The ACX6360 has two power supplies. Each power supply provides power to all components in the device. The two power supplies provide full power redundancy to the device. If one power supply fails or is removed, the second power supply balances the electrical load without interruption. To provide power redundancy to the system both power supplies must be installed. Connect power source feed A to one power supply and power source feed B to the second power supply.

CAUTION: Do not connect feed A and feed B to the same power supply input terminal.

- Cooling system—The ACX6360 has five fan modules. If a fan module fails and the remaining fan modules are unable to keep the ACX6360 within the desired temperature thresholds, chassis alarms occur and the ACX6360 can shut down.

ACX6360 Field-Replaceable Units

Field-replaceable units (FRUs) are components that you can replace at your site. The ACX6360 FRUs are hot-removable and hot-insertable—you can remove and replace them without powering off the ACX6360 or disrupting the routing function.

CAUTION: Replace a failed fan module with a new fan module within 30 seconds of removal to prevent chassis overheating.

Table 6 on page 23 lists the FRUs for the ACX6360 and actions to take before removing them.
Table 6: Required Actions Before Removing a FRU from the ACX6360

	Required Actions Before RemovalFRU
Power supplies (2)	Remove the power cord or cable for the power supply unit. See “Maintaining the ACX6360 Power Supplies” on page 100.
Fan modules (5)	See “Removing and Installing ACX6360 Fan Modules” on page 97.
Optical transceivers	None. It is recommend that you disable the interface by using the set interfaces interface-name disable command before you remove the transceiver. See “Removing and Installing ACX6360 Transceivers and Fiber-Optic Cables” on page 102.

NOTE: If you have a Juniper Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/. Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.

Fan Modules

The cooling system in an ACX6360 device consists of fan modules and a single fan in each power supply. There are five fan modules in the ACX6360. The airflow direction on the ACX6360 is airflow out, air comes into the device through the vents in the port panel.

The fanmodules in the ACX6360 are hot-insertable and hot-removable field-replaceable units (FRUs). These fan modules are designed for the airflow out direction. The fan modules are installed in the fan module slots on the management panel of the device next to the power supplies. The ACX6360 has 5 fan modules numbered 0 through 4 from left to right. Each fan module slot has a fan icon next to it.

Figure 8 on page 31 shows the location of the fan modules on the device.

Figure 9 on page 31 shows an example of the fan module.

Figure 8: ACX6360 FRU Panel

Figure 9 on page 31 shows the fan module for the ACX6360.

Figure 9: ACX6360 Fan Module

Technical line drawing of an air vent connector housing (no text or symbols)

You remove and replace a fan module from the FRU end of the chassis. The device continues to operate for a limited period of time (30 seconds) during the replacement of the fan module without thermal shutdown.

NOTE: All fan modules must be installed for optimal operation of the device.

Airflow Through the Chassis

In the ACX6360 cooling system, cool air enters through the vents in the port panel and hot air exhausts through the FRU panel. This type of airflow is known as airflow out or port-to-FRU airflow. When the chassis is installed, it must be positioned so that the FRUs are next to the hot aisle. Figure 10 on page 32 shows the airflow through the chassis.

ACX6360 Environmental Requirements and Specifications

The ACX6360 must be installed in a rack or cabinet. It must be housed in a dry, clean, well-ventilated, and temperature-controlled environment.

Follow these environmental guidelines:

• The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the efficiency of the ACX6360 cooling system.
• Maintain ambient airflow for normal ACX6360 operation. If the airflow is blocked or restricted, or if the intake air is too warm, the chassis might overheat, leading to the ACX6360 temperature monitor shutting down the router to protect the hardware components.

Table 21 on page 45 provides the required environmental conditions for normal ACX6360 operation.
Table 21: ACX6360 Environmental Tolerances

	ToleranceDescription
	No performance degradation up to 13,000 feet (3962.4 meters).Altitude
Relative humidity	Normal operation ensured in relative humidity range of 5% through 90%, noncondensing.Short-term operation ensured in relative humidity range of 5% through 93%, but not to exceed 0.026 kg water/kg of dry air.NOTE: As defined in NEBS GR-63-CORE, Issue 3, short-term events can be up to 96 hours in duration but not more than 15 days per year.
Temperature	Normal operation ensured in temperature range of 32^ F through 104^ F ( 0^ C through 40^ C).Nonoperating storage temperature in shipping container: -40^ F through 158^ F ( -40^ C through 70^ C).
	Designed to comply with Zone 4 earthquake requirements per NEBS GR-63-CORE, Issue 3.Seismic

NOTE: Install the ACX6360 only in restricted areas, such as dedicated equipment rooms and equipment closets, in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.

General Site Guidelines

Efficient device operation requires proper site planning and maintenance and proper layout of the equipment, rack or cabinet (if used), and wiring closet.

To plan and create an acceptable operating environment for your device and prevent environmentally caused equipment failures:

• Keep the area around the chassis free from dust and conductive material, such as metal flakes.
• Follow prescribed airflow guidelines to ensure that the cooling system functions properly and that exhaust from other equipment does not blow into the intake vents of the device.
• Follow the prescribed electrostatic discharge (ESD) prevention procedures to prevent damaging the equipment. Static discharge can cause components to fail completely or intermittently over time.
• Install the device in a secure area, so that only authorized personnel can access the device.

ACX6360 Chassis Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the ACX6360 must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground an ACX6360, connect a grounding cable to earth ground and then attach it to the chassis grounding points.

WARNING: The device is a pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earthing terminal must be permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.

WARNING: To comply with GR-1089 requirements, all intrabuilding copper cabling used for SFP+, QSFP+, and QSFP28 ports must be shielded and grounded at both ends.

CAUTION: Before device installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See “Connecting the ACX6360 Grounding Cable” on page 70. A cable with an incorrectly attached lug can damage the ACX6360.

Before connecting the ACX6360 to earth ground, review the following information:

• The grounding lug required is a Panduit LCD10-10A-L or equivalent (not provided). The grounding lug accommodates 14–10 AWG (2–5.3 mm ^2 ) stranded wire.
• The grounding cable that you provide for an ACX6360 must be the same size or heavier than the input wire of each power supply. Minimum recommendations are 14 AWG (2 mm ^2 ) stranded wire, 60° C wire, or as permitted by local code.

ACX6360 Clearance Requirements for Airflow and Hardware Maintenance

When planning the site for an ACX6360 installation, you must allow sufficient clearance around the installed chassis (see Figure 17 on page 47).

Figure 17: Clearance Requirements for Airflow and Hardware Maintenance for an ACX6360

Follow these guidelines:

• For the cooling system to function properly, the airflow around the chassis must be unrestricted. See "ACX6360 Cooling System" on page 30 for more information about the airflow through the chassis.
• If you are mounting an ACX6360 in a rack with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.
• You must leave at least 24 in. (61 cm) both in front of and behind the ACX6360 for servicepersonnel toremove and install hardware components, you must leave adequate space at the front and back of the ACX6360. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or cabinet and 24 in. (61 cm) behind the rack.

Site Electrical Wiring Guidelines

Table 23 on page 48 describes the factors you must consider while planning the electrical wiring at your site.

WARNING: You must provide a properly grounded and shielded environment and use electrical surge-suppression devices.

Table 23: Site Electrical Wiring Guidelines

	GuidelinesSite Wiring Factor
Signaling limitations	If your site experiences any of the following problems, consult experts in electrical surge suppression and shielding:Improperly installed wires cause radio frequency interference (RFI).Damage from lightning strikes occurs when wires exceed recommended distances or pass between buildings.Electromagnetic pulses (EMPs) caused by lightning damage unshielded conductors and electronic devices.
Radio frequency interference	To reduce or eliminate RFI from your site wiring, do the following:Use a 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, seek expert advice.Some of the problems caused by strong sources of electromagnetic interference (EMI) are:Destruction of the signal drivers and receivers in the deviceElectrical hazards as a result of power surges conducted over the lines into the equipment

ACX6360 Rack Requirements

The ACX6360 chassis is designed to be installed in four-post racks.

Rack requirements consist of:

• Rack type
• Mounting bracket hole spacing
• Rack size and strength

Table 24 on page 49 provides the rack requirements and specifications for the ACX6360.
Table 24: Rack Requirements for the ACX6360

	GuidelinesRack Requirement
Rack type: four-post	Use a four-post rack that provides bracket holes or hole patterns spaced at 1-U (1.75 in. or 4.45 cm) increments and that meets the size and strength requirements to support the weight.A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Components Industry Association (http://www.ecianow.org/).
Mounting bracket hole spacing	The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the ACX6360 can be mounted in any rack that provides holes spaced at that distance.
Rack size and strength	· Ensure that the rack complies with the standards for a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Components Industry Association (http://www.ecianow.org/).· Use a 600-mm 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).The horizontal spacing between the rails in a rack that complies with this standard is usually wider than the router's mounting brackets, which measure 19 in. (48.26 cm) from outer edge to outer edge. Use approved wing devices to narrow the opening between the rails as required.· Ensure that the rack rails are spaced widely enough to accommodate the ACX6360 chassis' external dimensions. The outer edges of the front-mounting rails extend the width to 19 in. (48.26 cm).· Ensure that the front and rear rack rails are spaced between 23.6 in. (60 cm) and 36 in. (91.4 cm) front-to-back.· Ensure that the rack is strong enough to support the weight of the device.· Ensure that the spacing of rails and adjacent racks allows for proper clearance around the ACX6360 and rack.
Rack connection to building structure	· Secure the rack to the building structure.· If earthquakes are a possibility in your geographical area, secure the rack to the floor.· Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum stability.

ACX6360 Cabinet Requirements

You can mount the ACX6360 in an enclosure or cabinet that contains a four-post 19-in. open rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.

Cabinet requirements consist of:

• Cabinet size and clearance
  • Cabinet airflow requirements

Table 25 on page 50 provides the cabinet requirements and specifications for the ACX6360.

Table 25: Cabinet Requirements for the ACX6360

	GuidelinesCabinet Requirement
Cabinet size and clearance	The minimum cabinet size for accommodating an ACX6360 device is 36 in. (91.4 cm) deep. Large cabinets improve airflow and reduce the chance of overheating.
Cabinet airflow requirements	When you mount the device in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.Ensure that the cool air supply you provide through the cabinet adequately dissipates the thermal output of the device.Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet without recirculating into the device. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.The ACX6360 fans exhaust hot air through the vents on the fans and power supplies. Install the device in the cabinet in a way that maximizes the open space on the FRU side of the chassis. This maximizes the clearance for critical airflow.Route and dress all cables to minimize the blockage of airflow to and from the chassis.Ensure that the spacing of rails and adjacent cabinets allows for the proper clearance around the device and cabinet.

Determining Transceiver Support for the ACX6360

The ACX6360 has 28 network ports. The 20 QSFP28 network ports on the port panel support QSFP+ and QSFP28 transceivers, direct-attach copper (DAC) cables, active optical cables (AOC), and DAC breakout cables (DACBO). You can configure each of the 20 ports as 10-Gigabit Ethernet ports, 40-Gigabit Ethernet ports, or 100-Gigabit Ethernet ports.

The8 CFP2 network ports on theport panel supportCFP2 transceivers. You can configure each of the 8 CFP2 ports as 100-Gigabit Ethernet ports or 200-Gigabit Ethernet ports.

See "ACX6360 Port Panel" on page 24 for more information about the network ports.

You can find information about the pluggable transceivers supported on your Juniper Networks device by using the Hardware Compatibility Tool. In addition to transceiver and connector type, the optical and cable characteristics—where applicable—are documented for each transceiver. The Hardware Compatibility Tool enables you to search by product, displaying all the transceivers supported on that device, or category, by interface speed or type. The list of supported transceivers for the ACX6360 is located at https://pathfinder.juniper.net/hct/product/#prd=ACX6360.

CAUTION: If you face a problem running a Juniper Networks device that uses a third-partyopticorbable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you checkthethird-partyopticor cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

Cable and Connector Specifications for the ACX6360

The transceivers that are supported on MX Series and PTX Series devices use fiber-optic cables and connectors. The type of connector and the type of fiber depends on the transceiver type.

You can determine the type of cable and connector required for your specific transceiver by using the Hardware Compatibility Tool.

CAUTION: To maintain agency approvals, use only a properly constructed, shielded cable.

NOTE: The terms multifiber push-on (MPO) and multifiber termination push-on (MTP) describe the same connector type. The rest of this topic uses MPO to mean MPO or MTP.

• 12-Fiber MPO Connectors on page 51
• 24-Fiber MPO Connectors on page 55
• LC Duplex Connectors on page 56

12-Fiber MPO Connectors

There are two types of cables used with 12-fiber MPO connectors on Juniper Networks devices—patch cables with MPO connectors on both ends, and breakout cables with an MPO connector on one end and four LC duplexconnectors on the opposite end. Depending on the application, the cables might use single-mode fiber (SMF) or multimode fiber (MMF). Juniper Networks sells cables that meet the supported transceiver requirements, but it is not required to purchase cables from Juniper Networks.

Ensure that you order cables with the correct polarity. Vendors refer to these crossover cables as key up to key up, latch up to latch up, Type B, or Method B. If you are using patch panels between two transceivers, ensure that the proper polarity is maintained through the cable plant.

Also, ensure that the fiber end in the connector is finished correctly. Physical contact (PC) refers to fiber that has been polished flat. Angled physical contact (APC) refers to fiber that has been polished at an angle. Ultra physical contact (UPC) refers to fiber that has been polished flat, to a finer finish. The required fiber end is listed with the connector type in the Hardware Compatibility Tool.

12-Fiber Ribbon Patch Cables with MPO Connectors

You can use 12-fiber ribbon patch cables with female MPO connectors to connect two transceivers of the same type—for example, 40GBASE-SR4-to-40GBASESR4 or 100GBASE-SR4-to-100GBASE-SR4. You can also connect 4x10GBASE-LR or 4x10GBASE-SR transceivers by using patch cables—for example,

4x10GBASE-LR-to-4x10GBASE-LR or 4x10GBASE-SR-to-4x10GBASE-SR—instead of breaking the signal out into four separate signals.

Table 26 on page 52 describes the signals on each fiber. Table 27 on page 53 shows the pin-to-pin connections for proper polarity.

Understanding Fiber-Optic Cable Signal Loss, Attenuation, and Dispersion

This topic describes signal loss, attenuation, and dispersion in fiber-optic cable.

• Signal Loss in Multimode and Single-Mode Fiber-Optic Cable on page 56
- Attenuation and Dispersion in Fiber-Optic Cable on page 57

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 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 over time. The following two types of dispersion can affect an optical data link:

• Chromatic dispersion—Spreading of the signal over time resulting from the different speeds of light rays.
• Modal dispersion—Spreading of the signal over 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 specifications for your optical interface to calculate the power budget and power margin for fiber-optic cables.

TIP: You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on your Juniper Networks device.

To calculate the power budget and power margin, perform the following tasks:

1. Calculating Power Budget for Fiber-Optic Cable on page 58
2. Calculating Power Margin for Fiber-Optic Cable on page 58

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 _B 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:

$$ P _ {M} = P _ {B} - L L $$

P_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, modal and chromatic dispersion, connectors, splices, and fiber attenuation. Table 30 on page 58 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 30: Estimated Values for Factors Causing Link Loss

	Estimated Link-Loss ValueLink-Loss Factor
Higher-order mode losses	Single mode—NoneMultimode—0.5 dB
Modal and chromatic dispersion	Single mode—NoneMultimode—None, if product of bandwidth and distance is less than 500 MHz-km0.5 dBConnector
	0.5 dBSplice
Fiber attenuation	Single mode—0.5 dB/kmMultimode—1 dB/km

The following sample calculation for a 2-km-long multimode link with a power budget ( P_B ) of 13 dB uses the estimated values from Table 30 on page 58 to calculate link loss (LL) asthesumoffiberattenuation (2 km @ 1 dB/km, or 2 dB) and lossfor five connectors (0.5 dB per connector, or 2.5 dB) and two splices (0.5 dB per splice, or 1 dB) as well as higher-order mode losses (0.5 dB). The power margins (Calculated as follows:

$$ P _ {M} = P _ {B} - L L $$

$$ P _ {M} = 1 3 \mathrm{dB} - 2 \mathrm{km} (1 \mathrm{dB/km}) - 5 (0. 5 \mathrm{dB}) - 2 (0. 5 \mathrm{dB}) - 0. 5 \mathrm{dB} $$

$$ P _ {M} = 1 3 \mathrm{dB} - 2 \mathrm{dB} - 2. 5 \mathrm{dB} - 1 \mathrm{dB} - 0. 5 \mathrm{dB} $$

$$ P _ {M} = 7 \mathrm{dB} $$

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 30 on page 58 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 calculated 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.

Figure 23: ACX6360 Grounding Points

Before you connect earth ground to the protective earthing terminal of an ACX6360 device, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable.

CAUTION: Using a grounding cable with an incorrectly attached lug can damage the switch.

NOTE: Mount your device in the rack before attaching the grounding lug to the switch. See "Unpacking and Mounting the ACX6360" on page 65.

Ensure that you have the following parts and tools available:

• Grounding cable for your ACX6360 device—The grounding cable must be 14 AWG (2 mm²), minimum 90°C wire, or as permitted by the local code.
• Grounding lug for your grounding cable—The grounding lug required is a Panduit LCD10-10A-L or equivalent.
• Two SAE 10-32 washers and screws—To attach the grounding lug to the protective earthing terminal.
• Screwdriver to attach the screws.

An AC-powered ACX6360 chassis gains additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See "ACX6360 AC Power Cord Specifications" on page 38.

To connect earth ground to an ACX6360 device:

1. Attach one end of the grounding cable to an appropriate earth ground site, such as the mounting rack.
2. Position the grounding lug over the protective earthing terminal on the side of the chassis, which is visible through the mounting bracket.

1. Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people could trip over it.

Connecting AC Power to the ACX6360

The ACX6360 is shipped from the factory with two power supplies. Each power supply is a hot-removable and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install replacement power supplies in the two slots next to the fan modules without powering off the device or disrupting the routing functions.

Ensure that you have the following parts and tools available:

• ESD grounding strap
• Power cord or cords appropriate for your geographical location available to connect AC power to the ACX6360 (see "ACX6360 AC Power Cord Specifications" on page 38).

Before you begin connecting AC power to the device:

• Read "General Electrical Safety Guidelines and Warnings" on page 151 and "Action to Take After an Electrical Accident" on page 152.
• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see "Prevention of Electrostatic Discharge Damage" on page 153).
• Ensure that you have connected the ACX6360 chassis to earth ground.

CAUTION: Before you connect power to the switch, a licensed electrician must attach a cablelug to the grounding and power cablesthatyousupply. A cable with an incorrectly attached lug can damage the switch (for example, by causing a short circuit). To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to the earth ground. For instructions on connecting earth ground, see "Connecting the ACX6360 Grounding Cable" on page 70. The switch gains additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see "ACX6360 AC Power Supply Description" on page 34).

- Install the power supply in the chassis following the instructions in "Installing a Power Supply in an ACX6360" on page 101.

CAUTION: Do not mix AC and DC power supplies in the same chassis.

NOTE: Each power supply must be connected to a dedicated power source outlet.

To connect AC power to an ACX6360:

1. Attach an electrostatic discharge (ESD) grounding strap to your barewrist, and connect the strap to an approved site ESD grounding point.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure. If only one power supply is installed, ensure that a blank coverpanel is installed over the second power supply slot.
3. Locate the power cord or cords shipped with the ACX6360; the cords have plugs appropriate for your geographical location. See "ACX6360 AC Power Cord Specifications" on page 38.

WARNING: Ensure that the power cord does not block access to router components or drape where people could trip on it.

1. Connect each power supply to the power sources. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.
2. Push the power cord retainer onto the power cord (see Figure 25 on page 73).

1. If the AC power source outlet has a power switch, set it to the off (O) position.

NOTE: The device powers on as soon as power is provided to the power supply. There is no power switch on the device.

1. Insert the power cord plug into an AC power source outlet.
2. If the AC power source outlet has a power switch, set it to the on (I) position.
3. Verify that the AC and DC LEDs on each power supply are lit green.

If the amber fault LED is lit, remove power from the power supply, and replace the power supply (see "Removing a Power Supply from the ACX6360" on page 100). Do not remove the power supply until you have a replacement power supply ready: the power supplies or a blank cover panel must be installed in the ACX6360 to ensure proper airflow.

CAUTION: Replace a failed power supply with a blank panel or newpower supply within 1 minute of removal to prevent the chassis from overheating.

Connecting DC Power to the ACX6360

The ACX6360 is shipped from the factory with two power supplies. Each power supply is a hot-removable and hot-insertable field-replaceable unit (FRU) when the second power supply is installed and running. You can install replacement power supplies in the two slots next to the fan modules without powering off the device or disrupting the routing functions.

WARNING: DC-powered ACX6360 models are intended for installation only in a restricted-access location.

NOTE: The battery returns of the DC power supply must be connected as an isolated DC return (DC-I).

Ensure that you have the following parts and tools available:

• ESD grounding strap
• DC power source cables (14–16 AWG) with ring lug (Molex 190700069 or equivalent) (not provided)
  • Phillips (+) screwdriver, number 2 (not provided)
• Multimeter (not provided)

Before you begin connecting DC power to the ACX6360:

- Read "General Electrical Safety Guidelines and Warnings" on page 151, "DC Power Electrical Safety Guidelines" on page 155, and the following warnings:

• DC Power Copper Conductors Warning on page 156
• DC Power Disconnection Warning on page 156
• DC Power Grounding Requirements and Warning on page 158
• DC Power Wiring Sequence Warning on page 159
• DC Power Wiring Terminations Warning on page 160

- Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see "Prevention of Electrostatic Discharge Damage" on page 153).

- Ensure that you have connected the ACX6360 chassis to earth ground.

CAUTION: Before you connect power to the switch, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the switch (for example, by causing a short circuit). To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must

connect the chassis to earth ground before you connect it to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to the earth ground. For instructions on connecting earth ground, see "Connecting the ACX6360 Grounding Cable" on page 70.

- Install the power supply in the chassis following the instructions in “Installing a Power Supply in an ACX6360” on page 101.

CAUTION: Do not mix AC and DC power supplies in the same chassis.

NOTE: Each power supply must be connected to a dedicated power source outlet.

To connect DC power to an ACX6360:

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point.

2. Verify that the DC power cables are correctly labeled before making connections to the power supply. In a typical power distribution scheme where the return is connected to chassis ground at the battery plant, you can use a multimeter to verify the resistance of the -48V and RTN DC cables to chassis ground:

3. The cable with very low resistance (indicating a closed circuit) to chassis ground is positive (+) and will be installed on the V+ (return) DC power input terminal.

4. The cable with very high resistance (indicating an open circuit) to chassis ground is negative (-) and will be installed on the V- (input) DC power input terminal.

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 DC power input terminals on each power supply.

1. Ensure that the input circuit breaker is open so that the voltage across the DC power source cable leads is 0 V and that the cable leads do not become active while you are connecting DC power.

NOTE: The V+ terminals are referred to as +RTN, and V- terminals are referred to as -48 V in "DC Power Wiring Sequence Warning" on page 159 and "DC Power Electrical Safety Guidelines" on page 155.

1. Ensure that the power supplies are fully inserted in the chassis.

2. Remove the terminal block cover. The terminal block cover is a piece of clear plastic that snaps into place over the terminal block (see Figure 26 on page 77).

3. Remove the screws on the terminals using the screwdriver. Save the screws.

WARNING: Ensure that the power cables do not block access to device components or drape where people can trip on them.

1. Connect each power supply to the power sources. Secure power source cables to the power supplies by screwing the ring lugs attached to the cables to the appropriate terminals by using the screw from the terminals (see Figure 26 on page 77 and

Figure 27 on page 77. The ACX6360 is designed to operate with a DC power supply that has a single, non-redundant, feed input. For source redundancy, two DC power supplies must be installed; connect source (A) to one power supply and connect source (B) to the second power supply. This configuration provides the commonly deployed A/B feed redundancy for the system.

The terminal block of the power supply has four terminals labeled V+, V+, V−, and V− for connecting DC power source cables labeled positive (+) and negative (−). The V+ terminals are shunted internally together, as are the V- terminals.

CAUTION: The connection between each power source and power supply must include a circuit breaker.

Do not connect two sources to a single power supply because doing so can potentially cause circulating current in feed wires whenever there is any difference in the voltage of the two sources.

a. Secure the ring lug of the positive (+) DC power source cable to the V+ terminal on the DC power supply.
b. Secure the ring lug of the negative (−) DC power source cable to the V- terminal on the DC power supply.
c. Tighten the screws on the power supply terminals until snug using the screwdriver. Do not overtighten—apply between 5 in-lb (0.56 Nm) and 6 in-lb (0.68 Nm) of torque to the screws.

Changing Operational Modes on the ACX6360

The ACX6360 can be used as either a transponder or a router. As a transponder, the ACX6360-OX has 16 100-Gbps ports that provide 1-to-1 cross-connects for pass-through connections of client interface traffic to line optical interfaces. As a router the ACX6360-OR provides IP/MPLS routing services.

The mode that the ACX6360 operates in, is determined by the software installed on the chassis. Each mode has its own Junos OS software.

• Router mode—Install the Junos-vmhost-base8-Install-acxor-x86-64 image.
• Transponder mode—Install the junos-vmhost-base8-install-acxox-x86-64 image.

NOTE: For information on installing Junos OS, see Software Installation and Upgrade Guide.

To change the ACX6360 chassis from router mode to transponder mode, all you need to do is install the transponder mode Junos OS software. Also, when changing from transponder mode to router mode, all you need to do is install the router mode Junos OS software.

NOTE: When you change the operational mode of the ACX6360, you lose all of the configuration settings that you configured in the previous mode. After changing modes, the system will come up in its factory (default) configuration.

Understanding Ethernet Fault Propagation

On the ACX6360-OX, when a local fault is received on the line side (et-0/1/y), it sends the local fault out on the client side (et-0/0/x). The client port then receives a remote fault (RF), which is then sent over on the line side (et-0/1/y). Figure 33 on page 88 shows the local fault (LF) detection on the line side.

Removing a Transceiver

The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting device functions.

NOTE: After you remove a transceiver or when you change the media-type configuration, wait for 6 seconds for the interface to display the operational commands.

Before you begin removing a transceiver from a device, ensure that you have taken the necessary precautions for the safe handling of lasers (see "Laser and LED Safety Guidelines and Warnings" on page 143).

Ensure that you have the following parts and tools available:

• An antistatic bag or an antistatic mat
• Rubber safety caps to cover the transceiver and fiber-optic cable connector
• A dust cover to cover the port or a replacement transceiver

Figure 41 on page 105 shows how to remove a QSFP+ transceiver. The procedure is the same for all types of transceivers except the QSFP28 and CFP transceivers.

To remove a transceiver from a device:

1. Place the antistatic bag or antistatic mat on a flat, stable surface.
2. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.
3. Label the cable connected to the transceiver so that you can reconnect it correctly.

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

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

CAUTION: Do not bend fiber-optic cables beyond their minimum bend radius. An arc smaller than a few inches in diameter can damage the cables and cause problems that are difficult to diagnose.

1. Remove the cable connected to the transceiver (see Disconnecting a Fiber-Optic Cable). Cover the transceiver and the end of each fiber-optic cable connector with a rubber safety cap immediately after disconnecting the fiber-optic cables.

2. To remove an SFP, SFP+, XFP, or a QSFP+ transceiver:

a. By using your fingers, pull open the ejector lever on the transceiver to unlock the transceiver.

CAUTION: Before removing the transceiver, make sure that you open the ejector levercompletely until you hear it click. This prevents damage to the transceiver.

b. Grasp the transceiver ejector lever and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight out of the port.

CAUTION: To prevent electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.

Figure 41: Removing an SFP, SFP+, XFP, or a QSFP+ Transceiver

1— Ejector lever

To remove a CFP transceiver:

a. Loosen the screws on the transceiver by using your fingers.

b. Grasp the screws on the transceiver and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight out of the port.

CAUTION: To prevent electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.

1. By using your fingers, grasp the body of the transceiver and pull it straight out of the port.

2. Place the transceiver in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

3. Place the dust cover over the empty port or install the replacement transceiver.

Installing a Transceiver

The transceivers for Juniper Networks devices are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting the device functions.

NOTE: After you insert a transceiver or after you change the media-type configuration, wait for 6 seconds for the interface to display operational commands.

NOTE: We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.

CAUTION: If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

Before you begin to install a transceiver in a device, ensure that you have taken the necessary precautions for safe handling of lasers (see “Laser and LED Safety Guidelines and Warnings” on page 143).

Ensure that you have a rubber safety cap available to cover the transceiver.

Figure 42 on page 108 shows how to install a QSFP+ transceiver. The procedure is the same for all types of transceivers except the QSFP28 and CFP transceivers.

To install a transceiver:

CAUTION: To prevent electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.

1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the switch.

2. Remove the transceiver from its bag.

3. Check to see whether the transceiver is covered with a rubber safety cap. If it is not, cover the transceiver with a rubber safety cap.

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

1. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later. If you are hot-swapping a transceiver, wait for at least 10 seconds after removing the transceiver from the port before installing a new transceiver.

2. Using both hands, carefully place the transceiver in the empty port. The connectors must face the chassis.

CAUTION: Before you slide the transceiver into the port, ensure that the transceiver is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable.

1. Slide the transceiver in gently until it is fully seated. If you are installing a CFP transceiver, tighten the captive screws on the transceiver by using your fingers.

2. Remove the rubber safety cap when you are ready to connect the cable to 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 cables connected to transceivers emit laser light that can damage your eyes.

Removing a QSFP28 Transceiver

28-Gbps quad small form-factor pluggable (QSFP28) are transceivers that can be removed from the device. QSFP28 transceivers are hot-insertable and hot-removable. Removing a QSFP28 transceiver does not interrupt the device functioning, but the removed QSFP28 transceiver no longer receives or transmits data.

Figure 43: 28-Gbps Quad Small Form-Factor Pluggable (QSFP28)

To remove a QSFP28 transceiver (see Figure 43 on page 108):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the QSFP28 transceiver. Have ready a rubber safety cap for the QSFP28 transceiver and the cable.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
3. Label the cable connected to the QSFP28 transceiver so that you can later reconnect it to the correct QSFP28 transceiver.
4. Disconnect the cable from the QSFP28 transceiver. 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.

1. 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.

1. Pull the transceiver's rubber handle straight back. The locking pins on the transceiver automatically release. Place the transceiver on the antistatic mat or in the electrostatic bag.

Installing a QSFP28 Transceiver

To install a replacement QSFP28:

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.

2. Verify that a rubber safety cap covers the QSFP28 transceiver, installing one if necessary.

3. Orient the QSFP28 over the port so that the QSFP28 connector faces the appropriate direction.

4. Slide the QSFP28 into the slot until the locking pins lock in place. If there is resistance, remove the QSFP28 and flip it so that the connector faces the other direction.

5. 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.

1. 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.

1. Verify that the status LEDs on the indicate that the QSFP28 is functioning correctly.

Disconnecting a Fiber-Optic Cable from the ACX6360

The ACX6360 has optical transceivers to which you can connect fiber-optic cables.

Before you disconnect a fiber-optic cable from an ACX6360, ensure that you have taken the necessary precautions for safe handling of lasers (see "Radiation from Open Port Apertures Warning" on page 145 and "Laser and LED Safety Guidelines and Warnings" on page 143).

Ensure that you have the following parts and tools available:

• Rubber safety cap to cover the transceiver
• Rubber safety cap to cover the fiber-optic cable connector

To disconnect a fiber-optic cable from an optical transceiver installed in the ACX6360:

1. (Recommended) Disable the port in which the transceiver is installed by including the disable statement at the [edit interfaces] hierarchy level for the specific interface:

[edit interfaces]

set Interface-name disable

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

WARNING: Do not stare into the laser beam or view it directly with optical instruments even if the interface has been disabled.

1. Carefully unplug the fiber-optic cable connector from the transceiver.

2. Cover the transceiver with a rubber safety cap.

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

1. Cover the fiber-optic cable connector with the rubber safety cap.

Connecting a Fiber-Optic Cable to the ACX6360

The ACX6360 has optical transceivers to which you can connect fiber-optic cables.

Before you connect a fiber-optic cable to an ACX6360, ensure that you have taken the necessary precautions for safe handling of lasers (see "Radiation from Open Port Apertures Warning" on page 145 and "Laser and LED Safety Guidelines and Warnings" on page 143).

To connect a fiber-optic cable to an optical transceiver installed in the ACX6360:

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

WARNING: Do not stare into the laser beam or view it directly with optical instruments even if the interface has been disabled.

1. If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.
2. If the optical transceiver is covered by a rubber safety cap, remove the cap. Save the cap.
3. Insert the cable connector into the optical transceiver.
4. Secure the cable so that it does not support its own weight. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.

CAUTION: Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius candamage the cables and cause problems that are difficult to diagnose.

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

Maintaining Fiber-Optic Cables in an ACX6360

To maintain fiber-optic cables in an ACX6360:

• When you unplug fiber-optic cables from transceivers, place rubber safety caps over the transceivers and on the end of the cables.

• Anchor fiber-optic cables to avoid stress on the connectors. When attaching a fiber-optic cable to a transceiver, be sure to secure the fiber-optic cable so that it does not support its own weight as it hangs to the floor. Never let a fiber-optic cable hang free from the connector.

• Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

• Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage the instruments, which are expensive to repair. 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 easier and less expensive to replace than the instruments.
• Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the transceiver or cable connector can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection.

To clean the transceiver canal, use an appropriate fiber-cleaning device such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions in the cleaning kit you use.

After cleaning the transceiver, 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 Cletop-S® Fiber Cleaner. Follow the directions in the cleaning kit you use.

- Always ensure that all modules, power supplies, and cover panels are fully inserted and that the installation screws are fully tightened.

Definitions of Safety Warning Levels

The documentation uses the following levels of safety warnings (there are two Warning formats):

NOTE: You might find this information helpful in a particular situation, or you might overlook this important information if it was not highlighted in a Note.

CAUTION: You need to observe the specified guidelines to prevent minor injury or discomfort to you or severe damage to the device.

WARNING: This symbol alerts you to the risk of personal injury from a laser.

WARNING: Thissymbolmeans danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents.

Qualified Personnel Warning

WARNING: Only trained and qualified personnel should install or replace the device.

Warning Statement for Norway and Sweden

WARNING: The equipment must be connected to an earthed mains socket-outlet.

Fire Safety Requirements

In the event of a fire emergency, the safety of people is the primary concern. You should establish procedures for protecting people in the event of a fire emergency, provide safety training, and properly provision fire-control equipment and fire extinguishers.

In addition, you should establish procedures to protect your equipment in the event of 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 all local fire, safety, and electrical codes and ordinances be observed when you install and operate your equipment.

Fire Suppression

In the event of an electrical hazard or an electrical fire, you should 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 and Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishers displace 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, you should use

this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves residues on equipment.

Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire extinguishers). The primary ingredient in these fire extinguishers is monoammonium phosphate, which is very sticky and difficult to clean. In addition, in the presence of 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: Tokeep warranties effective, donotusea dry chemicalfire 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.

Installation Instructions Warning

WARNING: Read the installation instructions before you connect the device to a power source.

If an electrical accident results in an injury, take the following actions in this order:

1. Use caution. Be aware of potentially hazardous conditions that could cause further injury.
2. Disconnect power from the device.
3. If possible, send another person to get medical aid. Otherwise, assess the condition of the victim, then call for help.

Prevention of Electrostatic Discharge Damage

Device components that are shipped in antistatic bags 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 when you are handling components that are subject to ESD damage, and make sure that it is in direct contact with your skin.

If a grounding strap is not available, hold the component in its antistatic bag (see Figure 48 on page 153) in one hand and touch the exposed, bare metal of the device with the other hand immediately before inserting the component into the device.

WARNING: For safety, periodically check the resistance value of the ESD grounding strap. The measurement must be in the range 1 through 10 Mohms.

• When handling any component that is subject to ESD damage and that is removed from the device, make sure the equipment end of your ESD wrist strap is attached to the ESD point on the chassis.
  If no grounding strap is available, touch the exposed,bare metal of the device to ground yourself before handling the component.
• Avoid contact between the component that is subject to ESDdamage and your clothing. ESD voltages emitted from clothing can damage components.
• When removing or installing a component that is subject to ESD damage, always place it component-side up on an antistatic surface, in an antistatic card rack, or in an antistatic bag (see Figure 48 on page 153). If you are returning a component, place it in an antistatic bag before packing it.

Figure 48: Placing a Component into an Antistatic Bag

CAUTION: ANSI/TIA/EIA-568 cables such as Category 5e and Category 6 can get electrostatically charged. To dissipate this charge, always ground the cables to a suitable and safe earth ground before connecting them to the system.

AC Power Electrical Safety Guidelines

CAUTION: For devices with AC power supplies, an external surge protective device (SPD) must be used at the AC power source.

The following electrical safety guidelines apply to AC-powered devices:

- Note the following warnings printed on the device:

"CAUTION: THIS UNIT HAS MORE THAN ONE POWER SUPPLY CORD. DISCONNECT ALL POWER SUPPLY CORDS BEFORE SERVICING TO AVOID ELECTRIC SHOCK."

"ATTENTION: CET APPAREIL COMPORTE PLUS D'UN CORDON D'ALIMENTATION. AFIN DE PRÉVENIR LES CHOCS ÉLECTRIQUES, DÉBRANCHER TOUT CORDON D'ALIMENTATION AVANT DE FAIRE LE DÉPANNAGE."

- AC-powered devices are shipped with a three-wire electrical cord with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this safety feature. Equipment grounding must comply with local and national electrical codes.

- You must provide an external certified circuit breaker (2-pole circuit breaker or 4-pole circuit breaker based on your device) rated minimum 20 A in the building installation.

- The power cord serves as the main disconnecting device for the AC-powered device. The socket outlet must be near the AC-powered device and be easily accessible.

- For devices that have more than one power supply connection, you must ensure that all power connections are fully disconnected so that power to the device is completely removed to prevent electric shock. To disconnect power, unplug all power cords (one for each power supply).

WARNING: The attached power cable is only for this product. Do not use the cable for another product.

注意

AC Power Disconnection Warning

WARNING: Before working on the device or near power supplies, unplug all the power cords from an AC-powered device.

DC Power Electrical Safety Guidelines

- A DC-powered device is equipped with a DC terminal block that is rated for the power requirements of a maximally configured device.

Incorporate an easily accessible disconnect device into the facility wiring. Be sure to connect the ground wire or conduit to a solid office earth ground. A closed loop ring is recommended for terminating the ground conductor at the ground stud.

- Run two wires from the circuit breaker box to a source of 48 VDC.

- A DC-powered device that is equipped with a DC terminal block is intended only for installation in a restricted-access location. In the United States, a restricted-access

area is one in accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code ANSI/NFPA 70.

NOTE: Primary overcurrent protection is provided by the building circuit breaker. This breaker must protect against excess currents, short circuits, and earth grounding faults in accordance with NEC ANSI/NFPA 70.

• Ensure that the polarity of the DC input wiring is correct. Under certain conditions, connections with reversed polarity might trip the primary circuit breaker or damage the equipment.
• For personal safety, connect the green and yellow wire to safety (earth) ground at both the device and the supply side of the DC wiring.
• The marked input voltage of -48 VDC for a DC-powered device is the nominal voltage associated with the battery circuit, and any higher voltages are only to be associated with float voltages for the charging function.
• Because the device is a positive ground system, you must connect the positive lead to the terminal labeled RTN, the negative lead to the terminal labeled -48 VDC, and the earth ground to the device grounding points.

DC Power Copper Conductors Warning

WARNING: Use copper conductors only.

DC Power Disconnection Warning

WARNING: Before performing any of the DC power procedures, 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 device handle of the circuit breaker in the OFF position.

DC Power 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 device. The grounding conductor is a separately derived system at the supply transformer or motor generator set.

WARNING: When you install the device, the ground connection must always be made first and disconnected last.

DC Power Wiring Sequence Warning

WARNING: Wire the DC power supply using the appropriate lugs. When connecting power, the proper wiring sequence is ground to ground, +RTN to +RTN, then -48 V to -48 V. When disconnecting power, the proper wiring sequence is -48 V to -48 V, +RTN to +RTN, then ground to ground. Note that the ground wire must always be connected first and disconnected last.

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 must be the appropriate size for the wires and must clamp both the insulation and conductor.

Multiple Power Supplies Disconnection Warning

WARNING: The network device has more than one power supply connection. All connections must be removed completely to remove power from the unit completely.

WARNING: The device is designed to work with a TN power system.
