User Manual
Step 1: Begin
In this guide, we provide a simple, three-step path, to quickly get you up and running with your new Juniper Networks ACX7100-32C Cloud Metro Router. We’ve simplified and shortened the installation and configuration steps, and included how-to videos. You’ll learn how to install an AC-powered ACX7100-32C in a rack, power it up, and configure basic settings. If you need instructions for installing a DC-powered ACX7100-32C, see the ACX7100-32C Hardware Guide.
Meet the ACX7100-32C
The ACX7100-32C Cloud Metro Router is a high-performance router with deep
buffer capabilities that address the increasing requirements of traffic growth
and latency-dependent applications. Powered by the Junos® OS Evolved operating
system, the ACX7100-32C routers offer high port density and MACsec–ready
ports, making them ideal for secure and high-end service aggregation and top-
of-rack, spine-and-leaf data center applications.
The ACX7100-32C router is a 1-U, fixed-configuration router that provides a
throughput of 4.8 Tbps while maintaining a power-efficient footprint. It has
32 QSFP28 ports that operate at 100-Gbps and four QSFP56-DD ports that operate
at 400-Gbps.
We ship the ACX7100-32C router with redundant power supplies. You can order it
with front-to-back airflow (airflow out or AO), and with AC or DC power
supplies.

Two #10-32 screws to secure the grounding lug
CAUTION: Ensure that a licensed electrician has attached the appropriate grounding lug to your grounding cable. Using a grounding cable with an incorrectly attached lug can damage the router.
Install the ACX7100-32C in a Rack
Here’s how to install the ACX7100-32C in a four-post rack:
- Review the General Safety Guidelines and Warnings.
- Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to a site ESD point.
- Decide which end of the router you want to place at the front of the rack. Position the router so that the AIR OUT labels are facing the hot aisle.
- Attach the mounting rails to the sides of the router using the 12 flat head screws.
- Lift the router and position it in the rack. Line up the bottom hole in each mounting rail with a hole in each rack rail, making sure the router is level.
- While you’re holding the router in place, have a second person insert and tighten the rack mount screws to secure the mounting rails to the rack rails. Make sure they tighten the screws in the two bottom holes first, and then tighten the screws in the two top holes.
- Continue holding the router in place, and have the second person slide the mounting blades into the channel of the mounting rails.
- Secure the mounting blades to the rack using the rack mount screws (and cage nuts and washers, if your rack requires them).
- Verify that the mounting brackets on each side of the rack are level.
NOTE: If you have unused ports, plug them using dust covers to prevent dust from entering the router.
Power On
Now that you’ve installed your ACX7100-32C in the rack, you’re ready to
connect it to power.
The AC-powered ACX7100-32C comes with two AC power supplies preinstalled on
the rear panel.
-
Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to one of the ESD grounding points on the router.
-
Use two #10-32 screws to secure the grounding lug and attached cable to the chassis. Attach the lug through the left rail and blade assembly to the chassis.
-
Connect the other end of the grounding cable to a proper earth ground, such as the rack.
-
Dress the grounding cable and ensure that it doesn’t touch or block access to other device components, and that it doesn’t drape where people could trip over it.
-
Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
-
For each power supply, ensure that the loop on the power cord retainer is open and there’s enough space to insert the power cord coupler into the inlet. If the loop is closed, press the small tab on the retainer to loosen the loop.
-
On the first power supply, thread the power cord coupler through the power cord retainer loop.
-
Plug in the power cord to the power supply socket.
-
Slide the power cord retainer loop toward the power supply until the loop is snug against the base of the coupler.
-
Press the tab on the loop, and draw out the loop into a tight circle. WARNING: Ensure that the power cord does not block access to router components or drape where people can trip on it.
-
If the AC power source outlet has a power switch, turn it off.
-
Plug in the power cord to the AC power source outlet.
-
If the AC power source outlet has a power switch, turn it on.
NOTE: The router powers on as soon as you connect it to power. The ACX7100-32C doesn’t have a power switch. -
Verify that the AC LED on the power supply is lit green. If the LED is lit steadily amber or is blinking amber, disconnect the power supply from the power source, and replace the power supply
(see Maintain the ACX7100-32C Power Supplies in the ACX7100-32C Cloud Metro Router Hardware Guide | Juniper Networks). -
Repeat steps 7 through 14 to power on the second power supply.
Step 2: Up and Running
Now that the ACX7100-32C is powered on, let’s do some initial configuration to
get it up and running on the network.
It’s simple to configure and manage the ACX7100-32C using the CLI.
Plug and Play
The ACX7100-32C router ships with factory-default settings that enable plug-
and-play operation. These settings load as soon as you power on the router.
Customize the Basic Configuration
You can easily customize the factory-default configuration with just a few
commands. Initially, you’ll need to make changes through the console port.
After you configure the management port, you can access the ACX7100-32C using
SSH and make additional configuration changes. You can always revert to the
factory-default configuration whenever you want.
Have the following information ready before you begin customizing the router:
- Hostname
- Root authentication password
- Management port IP address
- Default gateway IP address
- IP address and prefix length of remote prefixes
- (Optional) SNMP read community, location, and contact information
-
Verify that the following default serial port settings are configured on your laptop or desktop PC:
• Baud Rate—9600
• Flow Control—None
• Data—8
• Parity—None
• Stop Bits—1
• DCD State—Disregard -
Connect the console port on the ACX7100-32C to a laptop or desktop PC using the RJ-45 cable and RJ-45 to DB-9 adapter (not provided). The console (CON) port is the lower RJ-45 port on the right side of the port panel.
NOTE: If your laptop or desktop PC doesn’t have a serial port, use a serial-to-USB adapter (not provided). -
At the Junos OS login prompt, type root to log in.
You don’t need to enter a password. If the software boots before you connect your laptop or desktop PC to the console port, you might need to press the Enter key for the prompt to appear.
