ACX5048 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 Access Routers
Hardware Guide at http://www.juniper.net/techpubs/.
Starting in Release 15.1X54-D20, Junos OS supports the ACX5000 Universal Access
Routers (model numbers: ACX5048-DC and ACX5048-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 Series. The ACX5000 routers are available in AC and DC
power variants.
The following are the key features of the ACX5048 router:
•Forty-eight 10-Gigabit Ethernet SFP+ ports that can be configured as 1-Gigabit Ethernet
ports that support 1-gigabit small form-factor pluggable transceivers (SFP)
•Six 40-Gigabit Ethernet ports with quad form-factor pluggable plus transceivers
(QSFP+)
•Aggregate throughput of up to 1.44 Tbps
•Maximum power requirement of up to 350 W (with optical SFPs)
The ACX5048 router is a top-of-rack, 10-Gigabit Ethernet router with 48 SFP+ ports and
6 QSFP+ ports. Each SFP+ port can operate as a native 10-Gbps port or as a 1-Gbps port.
Each QSFP+ port (ports 48 through 53) can operate at native 40-Gbps speed or can be
channelized into four independent ports with 10-Gbps speed. The six QSFP+ ports can
be used as either access ports or uplink ports. The ACX5048 router has a 1 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 ACX5048 Universal
Access Router.

Step 1: Prepare the Site for ACX5048 Router Installation
Prepare your site for installing the ACX5048 router by observing the following guidelines:
•The ACX5048 router can be installed only in a four-post rack. 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.
•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 21.8 lb (9.8 kg).
•When planning the site for installing an ACX5048 router, you must provide sufficient
clearance around the installed chassis, as shown Figure 2 on page 3.

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 ACX5048 Router
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 ACX5048 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 the Grounding Cable

To connect power to an AC-powered router:
1. Attach the ESD 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 a DC-Powered ACX5048 Router
To connect power to a 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
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
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.
