Perform Initial Software Configuration of the ACX7509 Router

Before you begin connecting and configuring an ACX7509 router, set the following parameter values on the console server or PC:

  • Baud rate—9600

  • Flow control—None

  • Data—8

  • Parity—None

  • Stop bits—1

  • DCD state—Supported


When console is supported with DCD, TOD functionality cannot be supported. Console without DCD and TOD can be simultaneously supported when you use Y cable.

You must perform the initial configuration of an ACX7509 router through the console port by using the CLI.

To connect and configure the router from the console:

  1. Check that the ACX7509 has power.
  2. Connect the console (CON) port on the ACX7509 to a laptop or PC using an RJ-45 cable and RJ-45 to DB-9 adapter. The console (CON) port is located on the Routing Engine of the router.

    If your laptop or desktop PC doesn't have a serial port, use a serial-to-USB adapter (not provided).

  3. Log in as root.

    There is no password. If the software booted before you connected to the console port, you might need to press the Enter key for the prompt to appear.

  4. Start the CLI.
  5. Enter configuration mode.
  6. Add a password to the root administration user account.
  7. (Optional) Configure the name of the router. If the name includes spaces, enclose the name in quotation marks (“ ”).
  8. Configure the default gateway.
  9. Configure the IP address and prefix length for the router’s management interface.

    Although the CLI permits you to configure two management Ethernet interfaces within the same subnet, only one interface is usable and supported.


    The management ports, em0 or re0:mgmt-0 (MGMT for RJ-45 connections) and em1 (also labeled MGMT for fiber connections), are found on the front of the RCBs of the ACX7509 Router.

  10. (Optional) Configure the static routes to remote prefixes with access to the management port.
  11. Enable services such as SSH and Telnet.

    You will not be able to log in to the router as the root user through Telnet. Root login is allowed only through SSH.

  12. Commit the configuration to activate it on the router.
