What's in the Box?
Along with your ACX7509, you’ll also find:
•An accessory kit which includes:
•Warranty card
•Media kit (USB flash drivers)
•RJ-45 to DB-9 serial port adapter
•RJ-45 Ethernet cable
•RJ-45 Y-splitter cable
2

•AC power cord (country specific)
•Electrostatic discharge (ESD) wrist strap with cable
What Else Do I Need?
You’ll need:
•A mechanical lift rated for 250 lb (113.4 kg) to mount the router
•Three people to help you secure the router to the rack
•A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack-mount screws
•A management host such as a laptop or desktop PC
•A grounding cable: 4 AWG (21.1 mm²) stranded wire should be rated 90° C or per local electrical code, with a Panduit
LCD6-14A-L or equivalent lug attached
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 ACX7509 in a Rack
Here’s how to install the ACX7509 in a four-post rack:
1. Review the General Safety Guidelines and Warnings.
2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end to a site ESD
point.
3. 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.
4. Using a Phillips screwdriver, remove the screws on each side of the chassis that holds the rear mounting-blades to the
chassis.
3

5. Slide the mounting blades out of the channels.
6. Perform one of the following steps:
•Use a mechanical lift to position the ACX7509 in the rack so that the chassis flanges contact the rack rails and the
flange’s holes are aligned with the rack holes.
4

•With one person on each side and the third person to support the rear, hold on to the bottom of the chassis, and
carefully lift the chassis and position it in the rack so that the chassis flanges contact the rack rails and the flange’s
holes are aligned with the rack holes.
7. Continue to support the ACX7509 in place. Starting at the bottom, attach the chassis to the rack by installing mounting
screws through the flange and rack hole. Tighten the screws with the Phillips screwdriver.
5

8. Continue holding the router in place. Slide the mounting blades into the channels on either side of the chassis.
9. Secure the mounting blades to the rack rails using the rack moun\
t screws (and cage nuts and washers, if your rack requires them).
10. Visually inspect the alignment of the chassis. Make sure the router is level and the mounting screws on each side of
the rack are aligned.
If you’ve installed the chassis properly in the rack, all the mounting screws on one side of the rack are aligned with the
mounting screws on the opposite side, and the router is level.
NOTE: If you have unused ports, plug them using dust covers to prevent dust from entering the router.
6

11. Remove the M6 pan head screws from the chassis and secure the grounding lug and attached cable to the chassis with
the M6 pan head screws. The earthing terminal is on the rear side of the chassis.
12. Connect the other end of the grounding cable to a proper earth ground, such as the rack.
13. Dress the grounding cable. 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.
Power On
Now that you’ve installed your ACX7509 in the rack and grounded the chassis, you’re ready to connect it to power.
The ACX7509 router supports redundant AC/HDVC or DC power supplies that are pre-installed at the factory. In this
guide, we show you how to connect AC power for AC power installations. See the ACX7509 Router Hardware Guide for
information on DC power installation.
The AC-powered ACX7509 router comes with four AC power supplies preinstalled on the rear of the device.
1. 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.
2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
7

3. Plug the power cords into the power sockets of each AC power supply.
4. If the AC power outlet has a power switch, turn it off.
NOTE: The router powers on as soon as you connect it to power. The ACX7509 doesn't have a power switch.
5. Plug in each power cord to an AC power outlet.
WARNING: Ensure that the power cord does not block access to router components or drape
where people can trip on it.
6. If the AC power outlet has a power switch, turn it on.
7. 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 ACX7509 Power Supplies
in the ACX7509 Router Hardware Guide). Do not remove the power supply until you have a replacement power supply
ready.

Step 2: Up and Running
IN THIS SECTION
Plug and Play | 10
Customize the Basic Configuration | 10
Now that the ACX7509 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 ACX7509 using the CLI.
9

Plug and Play
The ACX7509 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 ACX7509 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
1. 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—Supported
NOTE: When console is supported with DCD, TOD functionality cannot be supported. Console without
DCD and TOD can be simultaneously supported when you use a Y cable.
2. Connect the console (CON) port on the ACX7509 to a laptop or PC using the supplied RJ-45 cable and RJ-45 to DB-9
adapter. You'll find the console (CON) port on the router's Routing Control Board (RCB).
NOTE: If your laptop or desktop PC doesn't have a serial port, use a serial-to-USB adapter (not provided).
10

3. 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.
login: root
4. Start the CLI.
root@% cli
5. Enter configuration mode.
root> configure
6. Add a password to the root administration user account.
[edit]
root@# set system root-authentication plain-text-password
New password: password
Retype new password: password
7. (Optional) Configure the name of the router. If the name includes spaces, enclose the name in quotation marks (“ ”).
[edit]
root@# set system host-name host-name
8. Configure the default gateway.
[edit]
root@# set system management-instance
root@# set routing-instances mgmt_junos routing-options static route prefix/prefix-length next-hop
default-gateway-ip-address
9. Configure the IP address and prefix length for the router management interface.
[edit]
root@# set interfaces re0:mgmt-0 unit 0 family inet address ip-address/prefix-length
CAUTION: Although the CLI permits you to configure two management Ethernet interfaces within
the same subnet, only one interface is usable and supported.
NOTE: You’ll find the management ports, em0 or re0:mgmt-0 (MGMT for RJ-45 connections) and em1 (also
labeled MGMT for fiber connections), on the front of the router's RCBs.
11

10. (Optional) Configure the static routes to remote prefixes with access to the management port.
[edit]
root@# set routing-options static route remote-prefix next-hop destination-ip retain no-readvertise
11. Enable services such as SSH and Telnet.
NOTE: You won’t be able to log in to the router as the root user through Telnet. You can only log in as root
through SSH.
[edit]
root@# set system services telnet
12. Commit the configuration to activate it on the router.
[edit]
root@# commit
