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.

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.
9

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
10

connect –48 V from feed B to the input terminals of the second power supply on the other side of the
chassis. This configuration provides the commonly deployed A/B feed redundancy for the system.
To connect the power supply to the power source:
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 they are snug by using the screwdriver. Do
not overtighten—apply between 5 lb-in (0.56 Nm) and 6 lb-in (0.68 Nm) of torque to the screws.
8. Replace the terminal block cover.
9. Close the input circuit breaker.
10. Verify that the DC LEDs are lit green and on steadily.
Step 5: Perform Initial Software Configuration
This procedure connects the router to the network but does not enable it to forward traffic. For complete
information about configuring the router to forward traffic, including examples, see the Junos OS
configuration guides.
You must perform the initial configuration of the router through the console port. Before you begin, set
the following parameter values in the console server or PC:
•Baud Rate—9600
•Flow Control—None
•Data—8
•Parity—None
•Stop Bits—1
•DCD State—Disregard
11

To connect and configure the router from the console:
1. Connect the console port to a laptop or PC by using the provided RJ-45 cable and RJ-45 to DB-9 serial
port adapter. The console (CON) port is located on the management panel of the router.
2. Log in as root. There is no password. If the software boots before you connect to the console port, you
might need to press the Enter key for the prompt to appear.
login: root
3. Start the command-line interface (CLI).
