Step 2: Up and Running

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. You can also onboard and manage the ACX7509 by using Paragon Automation. To onboard this device using Paragon Automation, see Onboard Cloud-Ready Devices with Paragon Automation.

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 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).

    Note:

    We no longer include the RJ-45 console cable with the DB-9 adapter as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:

    • RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)

    • RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)

    • RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)

    If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.

  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.

  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 management interface.

    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.

  10. (Optional) Configure the static routes to remote prefixes with access to the management port.

  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.

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