ACX5096 Quick Start Description

This Quick Start contains information you need to install and configure the router quickly. For complete

installation instructions, see the ACX5000 Universal Metro Routers Hardware Guide at

https://www.juniper.net/documentation/.

Starting in Release 15.1X54-D20, Junos OS supports the ACX5000 Universal Metro Routers (model

numbers: ACX5096-DC and ACX5096-AC). The ACX5000 routers are high-capacity and low-cost

aggregation routers best suited for Metro and Carrier Ethernet Aggregation deployments. The ACX5000

router portfolio consists of high-performance fixed-configuration routers that add higher port densities,

additional scalability, and improved latency to the ACX. The ACX5000 routers are available in AC and DC

power variants.

The key features of the ACX5096 router models are as follows:

•Ninety-six 10-Gigabit Ethernet SFP+ ports that can be configured to as 1-Gigabit Ethernet ports that

support 1GbE small form-factor pluggable transceivers (SFP)

•Eight 40-Gigabit Ethernet ports with quad form-factor pluggable plus (QSFP+) transceivers

•Aggregate throughput of up to 2.56 Tbps

•Maximum power requirement of up to 550 W (with optical SFPs)

The ACX5096 is a top-of-rack, 10-Gigabit Ethernet router with 96 SFP+ ports and 8 QSFP+ ports. Each

SFP+ port can operate as a native 10-Gbps port or as a 1-Gbps port. QSFP ports 96 and 100 can operate

at native 40-Gbps speed or can be channelized to four independent ports with 10-Gbps speed. The eight

QSFP+ ports can be used as either access ports or uplink ports. The ACX5096 router has a 2 U form factor

and is shipped with redundant fans and redundant power supplies. The router can be ordered with AC or

DC power supplies. Figure 1 on page 2 show the ACX5096 Universal Metro Router.

Step 1: Prepare the Site for ACX5096 Router

Installation

Prepare your site for installing the ACX5096 router by observing the following guidelines:

•The ACX5096 router can be installed in a two-post or four-post rack. Use a two-post or 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.

•Ensure that the spacing of rails and adjacent racks allows for proper clearance around the router and

rack.

•You need two people for installing the router–one for lifting the router and one for securing it. The

chassis weighs approximately 32.5 lb (14.74 kg).

•When planning the site for installing an ACX5096 router, you must provide sufficient clearance around

the installed chassis, as shown Figure 2 on page 3.

Install the Mounting Brackets

The ACX5096 router can be mounted in either a two or four-post rack configuration.

To mount the router in a 19-inch rack:

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

NOTE: If you are mounting multiple units in the rack, mount the heaviest unit at the bottom

and mount the others from bottom to top in order of decreasing weight. The router weighs

approximately 32.5 lb (14.74 kg). Installing the ACX5096 router in a rack or cabinet requires

two people to lift the router and secure it to the rack.

2. Place the rack in its permanent location, allowing adequate clearance for airflow and maintenance, and

secure it to the building structure.

3. Determine whether the end with field-replaceable units (FRUs) or the ports are to be placed at the

front of the rack.

4. Align a front mounting-rail (either flush with the front of the chassis or 2-in. recessed from the front)

along the side panel of the router chassis. See Figure 3 on page 5.

5. Attach the mounting rail to the router by using six mounting screws. Use cage nuts and washers if your

rack requires them.

6. Repeat Step 4 and Step 5 on the opposite side of the router.

Install the ACX5096 Router in the Rack

The router can be installed horizontally in a rack or cabinet.

Two people are required to install the ACX5096 router. The chassis weighs approximately 32.5 lb (14.74

kg). To install the chassis:

1. Ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation

site allows adequate clearance for both airflow and maintenance.

2. Position the router in front of the rack or cabinet.

3. Have one person grasp both sides of the router, lift it, and position it in the rack so that the front bracket

is aligned with the rack holes.

4. Have a second person secure the front of the router to the rack by using four mounting screws (and

cage nuts and washers if your rack requires them). Tighten the screws.

5. Continue to support the router while sliding the rear mounting-blades into the channel of the side

mounting-rails and securing the blades to the rack. Use the four mounting screws (and cage nuts and

washers if your rack requires them) to attach each blade to the rack. Tighten the screws.

6. Ensure that the router chassis is level by verifying that all the screws on the front of the rack are aligned

with the screws at the back of the rack. See Figure 4 on page 6.

You must ground the router before connecting power.

Tools Required to Ground the ACX5096 Router

Ensure that you have the following parts and tools available:

•Protective earthing terminal bracket—This bracket attaches to the ACX5096 router chassis through the

front mounting bracket on the left, providing a protective earthing terminal for the router.

•Grounding cable for your ACX5096 router—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 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.

Connect the Grounding Cable

To connect earth ground to an ACX5096 router:

1. Secure the provided protective earthing terminal bracket through the ACX5096 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 5 on page 8 and Figure 6 on page 8.

2. Connect one end of the grounding cable to a proper earth ground, such as the rack in which the router

is mounted.

3. Place the grounding lug attached to the grounding cable over the protective earthing terminal on the

protective earthing terminal bracket.

4. Secure the grounding lug to the protective earthing terminal with two nuts.

5. Dress the grounding cable and ensure that it does not touch or block access to other router components

and that it does not drape where people could trip over it.

Step 4: Connect Power to the ACX5096 Router

IN THIS SECTION

Connect AC Power to an AC-Powered ACX5096 Router | 9

Connect DC Power to an DC-Powered ACX5096 Router | 10

Depending on your configuration, your router uses either AC or DC power supplies. Perform the appropriate

procedures for each power supply in your router.

The power supply in an ACX5096 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 router functions.

WARNING: You must ground the router before connecting the power cables.

Connect AC Power to an AC-Powered ACX5096 Router

The ACX5096 router is supplied with two factory-installed power supplies.

To connect power to an AC-powered router:

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

2. If the AC power source outlet has a power router, set it to the off (0) position.

3. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.

4. Push the power cord retainer onto the power cord.

5. Insert the power cord plug into the power source outlet.

6. If the AC power source outlet has a power router, set it to the on (|) position.

7. Verify that the AC LEDs are lit green and on steadily.

Connect DC Power to an DC-Powered ACX5096 Router

To connect power to an DC-powered 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 is

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

is installed on the V– (input) DC power input terminal.

3. 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.

The V+ terminals are referred to as +RTN, and V– terminals are referred to as –48 V.

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

5. Remove the terminal block cover. The terminal block cover is a piece of clear plastic that snaps into

place over the terminal block.

6. Remove the screws on the terminals by using the screwdriver. Save the screws.

7. Connect each power supply to the power source. 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.

The DC 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. 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.

For example, connect –48 V from DC source feed A to the input terminals of one power supply and
