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. Copy the ex-script-snippet.conf file to the /var/tmp directory on your routing platform.

commit {
    file ex-script-snippet.xsl; } 

1. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode command:

[edit]
user@host# edit system scripts
[edit system scripts] 

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

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

For more information about the load command, see CLI Explorer.

ACX5000 Universal Metro Router Overview

The ACX5000 Universal Metro Routers are Juniper Networks' top-of-rack router solutions for data centers and campus distribution or aggregation environments. The ACX5000 router portfolio consists of high-performance fixed-configuration routers that add higher port densities, additional scalability, and improved latency to the ACX Series. The ACX5000 routers are available in two models—ACX5048 and ACX5096. See "ACX5000 Router Models" on page 19.

ACX5000 routers offer a compact 1 U model and a 2 U model that provide wire-speed packet performance, very low latency, and a rich set of Layer 2 and Layer 3 features. These routers have a high-throughput Packet Forwarding Engine, and the performance of the control plane running on ACX5000 routers is enhanced by the 1.5 Ghz dual-core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.

The ACX5000 routers include both 10-Gigabit Ethernet and 40-Gigabit Ethernet fixed configurations.

For more information about which features are supported on an ACX5000 routers, see "Protocols and Applications Supported by ACX Series Routers" on page 24.

ACX5000 routers use the Junos operating system (OS), which provides Layer 2 and Layer 3 switching, routing, and security services. Junos OS is installed on an ACX5000 router's 32-gigabyte (GB) internal solid state flash drive. The same Junos OS code base that runs on an ACX5000 routers also runs on all Juniper Networks QFX and EX Series switches, and J Series, M Series, MX Series, ACX Series and T Series routers.

You manage the router using the Junos OS command-line interface (CLI), accessible through the console and out-of-band management ports on the router.

Field-Replaceable Units in an ACX5000 Router

Field-replaceable units (FRUs) are components that you can replace at your site. The ACX5000 FRUs are hot-insertable and hot-removable: you can remove and replace them without powering off the router or disrupting the routing function.

The following are the ACX5000 FRUs:

• Power supplies
• Fan modules

Table 4 on page 20 lists the FRUs for the ACX5000 and actions to take before removing them.
Table 4: FRUs in ACX5000 Routers and Action Required Before Removing Them

	Required ActionFRUs
	NonePower supplies
	NoneFan modules

CAUTION: Replace a failed power supply with a blank panel or new power supply within one minute of removal to prevent chassis overheating. The router continues to operate with only one power supply running. Replace a failed fan module with a new fan module within one minute of removal to prevent chassis overheating. Do not operate the router with missing FRUs for longer than one minute.

NOTE: If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. 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.

NOTE: Before removing the optical transceivers, we recommend that you disable the interface using the set interfaces interface-name disable command. See "Disconnecting aFiber-OpticCable fromanACX5000Router" on page 109.

Understanding Hardware Redundancy of an ACX5000 Router Components and Functionality

The following hardware components provide redundancy on an ACX5000 router:

- Power supplies—The ACX5000 router has one or two power supplies. Each power supply provides power to all components in the router. If two power supplies are installed, 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 1 U ACX5048 router has five fan modules; the 2 U ACX5096 router has three fan modules. If a fan module fails and is unable to keep the ACX5000 router within the desired temperature thresholds, chassis alarms occur and the ACX5000 router can shut down.

Protocols and Applications Supported by ACX Series Routers

Table 7 on page 24 contains the first Junos OS Release support for protocols and applications on ACX Series routers. A dash indicates that the protocol or application is not supported.

NOTE:

• The [edit logical-systems logical-system-name] hierarchy level is not supported on ACX Series routers.
• TheACXSeriesrouters does not support per-family maximum transmission unit (MTU) configuration. The MTU applied to family inet gets applied to other families as well, even though it can be configured through CLI and visible in show Interface extensive output. The only way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet levels, and let it calculate for each familyautomatically. MTU valuesarenot limited to 1500 but can range between 256 to 9216.

Port Panel of an ACX5048 Router

The port panel of the ACX5048 supports up to a maximum of 72 logical 10 GbE ports when operating as a standalone router. Forty-eight physical ports(0 through 47) support 10 Gbps small form-factor pluggable plus (SFP+) transceivers. These ports can be configured as access ports. All 48 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP, 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any access port.

The remaining 24 logical ports are available for six 40 GbE ports (48 through 53) that support up to six quad small-form factor pluggable plus (QSFP+) transceivers or QSFP+. Each QSFP+ socket can operate either as a single 40 Gbps port or as a set of 4 independent 10 Ggps ports using QSFP+ breakout cables. The 40 GbE ports can be configured as either access ports or as uplinks.

CAUTION: Do not place a copper transceiver in an access port directly above or below another copper transceiver. Internal damage to the access ports and router can occur. We recommend either using the topportrow exclusively, or bottom port row exclusively, for copper transceivers.

Figure 9 on page 42 shows the port panel of a ACX5048 router.

Port Panel of an ACX5096 Router

The port panel of the ACX5096 router consists of 96 small form-factor pluggable plus (SFP+) and 8 quad small-form factor pluggable plus (QSFP+) ports. Physical ports(0 through 95) support 10 Gbps SFP+ transceivers and normally are configured as access ports. The eight 40-Gigabit ports (96 through 103) support QSFP+ transceivers and are normally configured as uplinks or Virtual Chassis ports (VCPs). Although the 104 physical ports of the ACX5096 would map to 128 logical ports using channelization, only 104 logical ports are supported.

Figure 10 on page 43 shows the port panel of a ACX5096 router.

  • Channelizing Interfaces on page 44

Router Ports

The ACX5096 ports, (0 through 95) support:

• 1 Gbps SFP transceivers
• 10 Gbps SFP+ transceivers
• 10 Gbps direct attach copper (DAC) cables

Ports 96 through 104 support:

• 40 Gbps QSFP+ transceivers

Additionally ports 96 and 100 support:

• QSFP+ direct attach copper (DAC) cables
- QSFP+ to SFP+ direct attach copper break out (DACBO) cables
• QSFP+ to SFP+ fiber break out cables

All 96 of these ports can be used for SFP+ transceivers or SFP+ direct attach copper (DAC) cables. You can use 1-Gigabit EthernetSFP+, 10-Gigabit Ethernet SFP+ transceivers and SFP+ direct attach copper cables in any access port.

CAUTION: Do not place a copper transceiver in an access port directly above or below another copper transceiver. Internal damage to the access ports and router can occur. Were recommend either using the top port row exclusively, or bottom port row exclusively, for copper transceivers.

Channelizing Interfaces

The port panel of an ACX5096 supports up to a maximum of 104 logical 10 GbE ports that can be distributed over 96 small form-factor pluggable plus (SFP+) and 8 quad small-formfactor pluggable plus (QSFP+) transceivers. Because of an 104 port restriction, only two of the eight QSFP+ can be channelized. Depending on how you set the system mode for channelization, the behavior of channelization for the QSFP+ changes. The following system modes are available for the ACX5096 router:

• Non-oversubscribed

All 96 SFP+ ports on the router (PIC 0) are supported. In this mode, the eight QSFP+ ports are not supported and cannot be channelized. There is no packet loss for packets of any size in this mode.

- Default mode

All 96 SFP+ ports on the router (PIC 0) are supported. QSFP+ ports 96 and 100 can be channelized. If ports 96 and 100 are channelized, the interfaces on ports 97, 98, 99, 101, 102, and 103 are disabled.

Chassis Status LEDs on an ACX5000 Router

The ACX5000 routers has four status LEDs on the FRU side of the chassis, next to the management ports (see Figure 11 on page 45).

Cooling System and Airflow in an ACX5000 Router

The cooling system in ACX5000 routers consists of fan modules and a single fan in each power supply. The number of fan modules vary depending whether the size of the router is 1 U or 2 U high. All routers can be set up to work in the following airflow direction:

• Airflow Out (AFO)—Air comes into the router through the vents in the front panel.

This topic describes:

• Fan Modules on page 51
• Fan Module Status on page 53

Fan Modules

The fan modules in ACX5000 routers are hot-insertable and hot-removable field-replaceable units (FRUs). These fan modules are designed for air to enter from the ports to the FRU-Airflow Out. The fan modules are installed in the fan module slots on the management panel of the router next to the power supplies.

Both the 1 U and 2 U versions of ACX5000 fan modules have a similar design with different dimensions. The 1 U ACX5000 routers have 5 fan modules numbered 0 through 4 from left to right, where the 2 U, ACX5096 has 3 fan modules numbered 0 through 2. On all ACX5000 routers, each fan module slot has a fan icon next to it.

Figure 13 on page 51 shows the 1 U fan module and Figure 14 on page 52 shows the 2 U fan module.

Figure 13: 1 U Fan Module Used in ACX5048

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

Figure 14: 2 U Fan Module Used in ACX5096

Technical line drawing of a mechanical device with labeled components (AIR OUT, AFO), no readable text or symbols beyond labels

You remove and replace a fan module from the FRU end of the chassis. The router 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 router.

The fan module airflow direction (port-to-FRU, AFO) is indicated by either a gold color or the label AIR OUT. Table 13 on page 52 lists the fan module product SKUs and the direction of airflow in them:

Fan Module Status

You can check the status of fan modules through the show system alarms command or by looking at the LEDs next to each fan module.

Each router has a Status LED (labeled ST) for each fan module on the left side of the corresponding fan module slot. It indicates the status of all the fan modules.

Table 14 on page 54 describes the Status LED on the fan module in an ACX5000 router.

Table 14: Fan Module LED

	DescriptionLED State
Solid Green	The individual fan module is present. After the hardware senses the fan module, software ensures the airflow is consistent with the other fan modules and that it is functioning correctly.
Blinking Amber	Indicates one of the following:· The fan module is not present.· The fan module is not functioning normally.

Under normal operating conditions, the fan modules operate at a moderate speed. Temperature sensors in the chassis monitor the temperature within the chassis.

The system raises an alarm if a fan module fails or if the ambient temperature inside the chassis rises above the acceptable range. If the temperature inside the chassis rises above the threshold temperature, the system shuts down automatically.

AC Power Supply for an ACX5000 Router

The two power supplies in ACX5000 routers are hot-removable and hot-insertable field-replaceable units (FRUs). The power supplies are installed in the router at the factory. You can install replacement power supplies from the management panel without powering off the router or disrupting the router function.

The AC power supply in 1 U ACX5048 is 650 W; the AC power supply in the 2 U ACX50 is 850 W. Both power supplies look identical. Be sure to use the correct power supply for your chassis product SKU (see Table 16 on page 57).

CAUTION: Do not mix power supplies with different wattage. The system raises an alarm when a power supply having a different wattage is inserted into the chassis.

See Figure 18 on page 56 for an example of the 1 U design and Figure 19 on page 56 for an example of the 2 U power supply.

Figure 18: 1 U AC Power Supply in an ACX5048

Figure 19: 2 U AC Power Supply in an ACX5096

The power supply provides port-to-FRU airflow depending on the product SKU you purchase. The power supplies either have labels on the handles that indicate the direction of airflow or they have color-coded handles with a fan icon. See Figure 20 on page 56 for an example of the power supply. A power supply with the label AFO or a gold-colored handle denotes port-to-FRU airflow.

Figure 20: Power Supply Handle Detail

CAUTION: Verify that the airflow direction on the power supply handle matches the direction of airflow in the chassis. Ensure that each powersupply you install in the chassis has the same airflow direction.

To avoid electrical injury, carefully follow instructions in "Connecting AC Power to an ACX5000 Router" on page 93.

DC Power Supply for an ACX5000 Router

The power supplies in ACX5000 routers (see Figure 22 on page 59) are hot-removable and hot-insertable field-replaceable units (FRUs) that you can install in 1U DC ACX5048 SKUs of ACX5000 routers without powering off the router or disrupting the routing function.

The DC power supply in 1 U ACX5048 is 650 W with dual feeds for power resiliency. The DC power supply in the 2 U ACX5096 is 850 W with dual feeds for power resiliency. Both power supplies have a similar design and look identical. Be sure to use the correct power supply for your chassis product SKU (see Table 18 on page 60). See Figure 22 on page 59 for an example of the 1 U design and Figure 23 on page 59 for an example of the 2 U power supply.

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.

QFX5120 Site Electrical Wiring Guidelines

Table 24 on page 67 describes the factors you must consider while planning the electrical wiring at your site.

WARNING: It is particularly important to provide a properly grounded and shielded environment and to use electrical surge-suppression devices.

Table 24: 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

Clearance Requirements for Airflow and Hardware Maintenance for an ACX5000 Router

When planning the site for installing an ACX5000 router, you must allow sufficient clearance around the installed chassis (see Figure 26 on page 68).

Figure 26: Clearance Requirements for Airflow and Hardware Maintenance for an ACX5000 Router

• For the cooling system to function properly, the airflow around the chassis must be unrestricted. See "Cooling System and Airflow in an ACX5000 Router" on page 51 for more information about the airflow through the chassis.
• If you are mounting an ACX5000 router in a rack or cabinet with other equipment, ensure that the exhaust from other equipment does not blow into the intake vents of the chassis.
• Leave atleast 24in. (61 cm) both in front of and behind the ACX5000 router. For service personnel to remove and install hardware components, you must leave adequate space at the front and back of the router. 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 or cabinet.

ACX5000 Router Environmental Specifications

The router 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 router cooling system.
• Maintain ambient airflow for normal router operation. If the airflow is blocked or restricted, or if the intake air is too warm, the router might overheat, leading to the router temperature monitor shutting down the device to protect the hardware components.

Table 26 on page 69 provides the required environmental conditions for normal router operation.
Table 26: ACX5000 Router Environmental Tolerances

	ToleranceDescription
	No performance degradation to 6,562 feet (2000 meters)Altitude

ACX5000 Chassis Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, the router must be adequately grounded before power is connected to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground a ACX5000 router, connect a grounding cable to earth ground and then attach it to the chassis grounding points.

WARNING: The router is 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 intra-building copper cabling used for SFP+ and QSFP+ ports must be shielded and grounded at both ends.

CAUTION: Before router installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See "Connecting the ACX5000 Router to Earth Ground" on page 92. A cable with an incorrectly attached lug can damage the router.

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

• A protective earthing terminal bracket is provided in the accessory kit for connecting the router to earth ground. This L-shaped bracket attaches to a post on the ACX5000 router left front mounting bracket, providing a protective earthing terminal for the router. The grounding points are studs sized for M4 hex nuts. The grounding points are spaced at 0.625 in. (15.86 mm). M4 hex nuts with integrated washers are provided in the accessory kit.
• The grounding lug required is a Panduit LCD10-10A-L or equivalent. This grounding lug is provided in the accessory kit. The grounding lug provided accommodates 14–10 AWG (2–5.3 mm ^2 ) stranded wire.
• The grounding cable that you provide for a ACX5000 router must be 14 AWG (2 mm ^2 ), minimum 60° C wire, or as permitted by the local code.

Cabinet Requirements for an ACX5000 Router

You can mount an ACX5000 router 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 27 on page 71 provides the cabinet requirements and specifications for an ACX5000 router.
Table 27: Cabinet Requirements for an ACX5000 Router

	GuidelinesCabinet Requirement
Cabinet size and clearance	ThemInimum cabinet size for accommodatinga ACX5000router is 36in. (91.4cm) deep. Large cabinets improve airflow and reduce the chance of overheating.
Cabinet airflow requirements	When you mount the router in a cabinet, ensurethatventilationthrough 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 router (or routers).Ensure that the cabinet allows the chassis hot exhaust air to exit the cabinet without recirculating into the router. 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 ACX5000 router fans exhaust hot air either through the vents on the port panel or through the fans and power supplies. Install the router 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 router and cabinet.

Rack Requirements for an ACX5000 Router

All ACX5000 routers are designed to be installed on four-post racks. The ACX5096 can also be installed on two-post racks.

Rack requirements consist of:

• Rack type
• Mounting bracket hole spacing

- Rack size and strength

Table 28 on page 72 provides the rack requirements and specifications for an ACX5000 router.

Table 28: Rack Requirements for an ACX5000 Router

	GuidelinesRack Requirement
Rack type (all router models)	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 Industry Association.
Rack type (ACX5096 only)	Use a two-post or four-post rack that provides bracketholes or hole patternsspacedat 1 U (1.75 in. or 4.45 cm) increments and that meets the size and strength requirements to support the weight.
Mounting bracket hole spacing (all router models)	The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the router can be mounted in any rack that provides holes spaced at that distance.
Rack size and strength (all router models)	Ensure that the rack complies with the standards for a 19-in. or 23-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310-D) published by the Electronics Industry Association.A 600-mm rack as defined in the four-part Equipment Engineering (EE); European telecommunications standard for equipment practice (document numbers ETS300 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 device'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 router chassis' external dimensions. The outer edges of the front-mounting brackets extend the width to 19 in. (48.26 cm).For four-post installations, the front and rear rack rails must be spaced between 23.6 in. (60 cm) and 36 in. (91.4 cm) front-to-back.The rack must be strong enough to support the weight of the router.Ensure that the spacing of rails and adjacent racks allows for proper clearance around the router 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.

Determining Transceiver Support for the ACX5000

All the router models of the ACX5000 router supply quad small form-factor pluggable plus (QSFP+) ports for use as uplinks or as access ports. These 40 GbE ports support QSFP+ transceivers, QSFP+ direct-attach copper (DAC) cables, and DAC breakout cables (DACBO). The ACX5048 has 6 QSFP+ ports; the ACX5096 has 8 QSFP+ ports that can all be used as uplinks.

On all ACX5000 routers, the ports are enabled by default.

Downlink ports are product SKU-specific:

• ACX5096—has 96 SFP+ ports that support SFP and SFP+ transceivers, as well as DAC cables.
• ACX5048—has 48 SFP+ ports that support SFP and SFP+ transceivers, as well as DAC cables.

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 ACX5000 is located at https://pathfinder.juniper.net/hct/product/#prd=ACX5000.

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.

Figure 27 on page 74 shows the location of SFP+ and QSFP+ ports for the ACX5096, Figure 28 on page 74 shows these ports for the ACX5048.

Cable Specifications for QSFP+ and QSFP28 Transceivers

The 40-Gigabit Ethernet QSFP+ and 100-Gigabit Ethernet QSFP28 transceivers that are used in ACX routers use 12-ribbon multimode fiber crossover cables with female MPO connectors (SR4 optics only). The fiber can be either OM3 or OM4. These cables are not sold by Juniper Networks.

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

TIP: 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 QSFP+ or QSFP28 transceivers, ensure that the proper polarity is maintained through the cable plant.

Table 29 on page 74 describes the signals on each fiber. Table 30 on page 75 shows the pin to pin connections for proper polarity.

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 76
2. Calculating Power Margin for Fiber-Optic Cable on page 76

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 _B ) (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 31 on page 77 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 31: Estimated Values for Factors Causing Link Loss

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

The following sample calculation for a 2-km-long multimode link with a power budget ( P_B ) of 13 dB uses the estimated values from Table 31 on page 77 to calculate link loss (LL) asthesumoffiberattenuation (2 km @ 1 dB/km, or 2 dB) and loss for fiveconnectors (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 31 on page 77 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.

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 78
- Attenuation and Dispersion in Fiber-Optic Cable on page 78

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.

Connecting the ACX5000 Router to Earth Ground

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the ACX5000 router to earth ground before you connect it to power.

For installations that require a separate grounding conductor to the chassis, you must attach a protective earthing terminal bracket on the ACX5000 router left front mounting bracket to connect to the earth ground (see Figure 35 on page 93).

Before you connect earth ground to the protective earthing terminal of a ACX5000 router, 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 router.

NOTE: Mount your router in the rackor cabinetbeforeattaching the grounding lug to the router. See "Mounting an ACX5000 Router in a Rack or Cabinet" on page 85.

Ensure that you have the following parts and tools available:

• Protective earthing terminal bracket—This bracket attaches to the router chassis through the left front mounting bracket, providing a protective earthing terminal for the router.
• Grounding cable for your router—The grounding cable must be 14 AWG (2 mm ^2 ), 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 M4 hex nuts with integrated washers—Two nuts and washers are used to secure the grounding lug to the grounding lug bracket protective earthing terminal. Four nuts are provided in the accessory kit.
• 7-mm wrench or socket with driver to attach the two nuts.

An AC-powered ACX5000 router chassis gains additional grounding when you plug the power supply in the router into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See “AC Power Cord Specifications for an ACX5000 Router” on page 62.

To connect earth ground to a ACX5000 router:

1. Secure the provided protective earthing terminal bracket through the ACX5000 router mounting bracket to the chassis with the nut provided. The posts on the protective earthing terminal bracket should point to the left. See Figure 35 on page 93 and Figure 36 on page 93.

Connecting AC Power to an ACX5000 Router

The power supply in an ACX5000 router is a hot-removable and hot-insertable field-replaceable unit (FRU). You can remove and replace it without powering off the router or disrupting routing functions.

Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the router.

Before you begin connecting AC power to the router:

• Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see “Prevention of Electrostatic Discharge Damage” on page 155).
• Ensure that you have connected the router chassis to earth ground.

CAUTION: Before you connect power to the router, 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 router (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 router chassis to connect to the earth ground. For instructions on connecting earth ground, see "Connecting the ACX5000 Router to Earth Ground" on page 92. The router gains additional grounding when you plug the power supply in the router into a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see "AC Power Supply for an ACX5000 Router" on page 55).

- Install the power supply in the chassis. For instructions on installing a power supply in a ACX5000 router, see “Installing a Power Supply in an ACX5000 Router” on page 116.

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

To connect AC power to an ACX5000 router:

1. Attach the grounding strap to your bare wrist and to a site ESD point.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure. If only one powersupply is installed, ensure a that blankcover panel is installed over the second power supply slot.
3. Locate the power cord or cords shipped with the router; the cords have plugs appropriate for your geographical location. See "AC Power Cord Specifications for an ACX5000 Router" on page 62.

WARNING: Ensure that the power cord does not block access to device components or drape where people can 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 37 on page 95 and Figure 38 on page 95).

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

NOTE: The router powers on as soon as power is provided to the power supply. There is no power router 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 router, 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 an ACX5000 Router" on page 114).

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 router to ensure proper airflow.

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

CAUTION: A system reboot with Routing Engine FPGA version 7.1 might not successfully boot the Junos OS software. In case of a system reboot failure, you need to power cycle the router. To check the current FPGA version, issue the show chassis firmware command.

See Also AC Power Supply for an ACX5000 Router on page 55.

•AC Power Supply LEDs on an ACX5000 Router on page 57

Connecting DC Power to an ACX5000 Router

The power supply in an ACX5000 router is a hot-removable and hot-insertable field-replaceable unit (FRU). You can remove and replace it without powering off the router or disrupting routing functions.

WARNING: DC-powered ACX5000 routers 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).

Before you begin connecting DC power to the router:

• Ensure that you havetaken the necessary precautions to prevent electrostatic discharge (ESD) damage (see "Prevention of Electrostatic Discharge Damage" on page 155).
• Ensure that you have connected the router chassis to earth ground.

CAUTION: Before you connect power to the router, 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 router (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 router chassis to connect to the earth ground. For instructions on connecting earth ground, see “Connecting the ACX5000 Router to Earth Ground” on page 92.

- Install the power supply in the chassis. For instructions on installing a power supply in a ACX5000 router, see "Installing a Power Supply in an ACX5000 Router" on page 116.

Ensure that you have the following parts and tools available:

• 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)

To connect DC power to an ACX5000 router:

1. Attach the grounding strap to your bare wrist and to a site ESD 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:

- 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.

- 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 161 and "ACX5000 DC Power Electrical Safety Guidelines and Warnings" on page 158.

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 39 on page 99).

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 39 on page 99 and Figure 40 on page 99).

The ACX5000 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 in ACX5000; 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 powersource 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.

CAUTION: The V+ terminals are shunted internally together, as are the V- terminals. The same polarity terminal can be wired together from the same source to provide an additional current path in a higher power chassis. Do not connect the terminals to different sources.

Figure 40: Securing Ring Lugs to the Terminals on the ACX5000 DC Power Supply

1. Replace the terminal block cover.
2. Close the input circuit breaker.

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

1. Verify that the IN and OUT LEDs on the power supply are lit green and are on steadily.

CAUTION: A system reboot with Routing Engine FPGA version 7.1 might not successfully boot the Junos OS software. In case of a system reboot failure, you need to power cycle the switch. To check the current FPGA version, issue the show chassis firmware command.

Removing a Transceiver from an ACX5000 Router

The transceivers for the ACX routers are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the router or disrupting routing functions.

Before you begin removing a transceiver from the ACX routers, ensure that you have taken the necessary precautions for safe handling of lasers (see "Laser and LED Safety Guidelines and Warnings for the ACX5000 Router" on page 144).

Ensure that you have the following parts and tools available:

• Antistatic bag or an antistatic mat

• Needle-nose pliers

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

• Dust cover to cover the port

To remove a transceiver from an ACX5000 router:

1. Place the antistatic bag or antistatic mat on a flat, stable surface.

2. 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. Bending the cables beyond their minimum bend radius and cause problems that are difficult to diagnose.

1. Remove the cable connected to the transceiver (see "Disconnecting a Fiber-Optic Cable from an ACX5000 Router" on page 109). 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. Using your fingers, pull the ejector lever away from the transceiver to unlock the transceiver.

CAUTION: Before removing the transceiver, makesure you open the ejector lever completely until you hear it click. This prevents damage to the transceiver.

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

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

Disconnecting a Fiber-Optic Cable from an ACX5000 Router

The ACX routers has field-replaceable unit (FRU) optical transceivers to which you can connect fiber-optic cables.

Before you disconnect a fiber-optic cable from an optical transceiver installed in an ACX router, ensure that you have taken the necessary precautions for safe handling of lasers (see "Laser and LED Safety Guidelines and Warnings for the ACX5000 Router" on page 144).

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 an ACX5000 router:

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.

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 an ACX5000 Router

The ACX routers has field-replaceable unit (FRU) optical transceivers to which you can connect fiber-optic cables.

Before you connect a fiber-optic cable to an optical transceiver installed in an ACX router, ensure that you have taken the necessary precautions for safe handling of lasers (see "Laser and LED Safety Guidelines and Warnings for the ACX5000 Router" on page 144).

To connect a fiber-optic cable to an optical transceiver installed in an ACX5000 router:

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. 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 cables so that they are not supporting their 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 ACX5000 Router

To maintain fiber-optic cables in an ACX5000 router:

• When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver and on the end of the cable.
• Anchor fiber-optic cable 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 is not supporting

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.

Chassis and Component Lifting Guidelines

• Before moving the device to a site, ensure that the site meets the power, environmental, and clearance requirements.
• Before lifting or moving the device, disconnect all external cables and wires.
• As when lifting any heavy object, ensure that most of the weight is borne by your legs rather than your back. Keep your knees bent and your back relatively straight. Do not twist your body as you lift. Balance the load evenly and be sure that your footing is firm
• Use the following lifting guidelines to lift devices and components:
  • Up to 39.7 lb (18 kg): One person.
  • 39.7 lb (18 kg) to 70.5 lb (32 kg): Two or more people.
• 70.5 lb (32 kg) to 121.2 lb (55 kg): Three or more people.
• Above 121.2 lbs (55 kg): Material handling systems (such as levers, slings, lifts and so on) must be used. When this is not practical, specially trained persons or systems must be used (riggers or movers).

Restricted Access Warning

WARNING: This unit is intended for installation in restricted access areas. A restricted accessareaisanareatowhichaccesscan be gainedonly by service personnel through the use of a special tool, lock and key, or other means of security, and which is controlled by the authority responsible for the location.

WARNING: When installing the device, do not use a ramp inclined at more than 10 degrees.

Rack-Mounting and Cabinet-Mounting Warnings

Ensure that the rack or cabinet in which the device is installed is evenly and securely supported. Uneven mechanical loading could lead to a hazardous condition.

Action to Take After an Electrical Accident

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 57 on page 156) 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 ESD damage 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 57 on page 156). If you are returning a component, place it in an antistatic bag before packing it.

Figure 57: 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).

ACX5000 DC Power Electrical Safety Guidelines and Warnings

The following electrical safety guidelines apply to a DC-powered router:

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

NOTE: To supply sufficient power, terminate the DC input wiring on a facility DC source that is capable of supplying:

• Minimum of 7 A at -48 VDC for ACX5000 router

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.
