USB Autoinstallation on ACX Series Routers

If you have a new ACX Series router, you can use a Disk-on-Key USB memory stick (“USB key”) to configure the router.

This configuration method has the following requirements:

  • A management device (PC or laptop).
  • A Disk-on-Key device with one of the following 16-bit or 32-bit file allocation table (FAT) file systems:
    • DOS 3.0+ 16-bit FAT (up to 32 MB)
    • DOS 3.31+ 16-bit FAT (over 32 MB)
    • FAT32
    • FAT32, LBA-mapped
    • 16-bit FAT, LBA-mapped
  • An ACX Series router with the factory configuration. If other Junos OS configuration files exist on the router, the router cannot read the juniper-config.txt file from the Disk-on-Key device.

    Note: The USB-based autoinstallation process overrides the network-based autoinstallation process. If the ACX Series router detects a USB Disk-on-Key device containing a valid configuration file during autoinstallation, it configures the router using the configuration file on Disk-on-Key instead of fetching the configuration from the network.

To configure an ACX Series router using Disk-on-Key:

  1. Using a text editor on a PC or laptop, create the configuration file, named juniper-config.txt, as a sequence of configuration commands (“set” commands). To reuse configuration from another ACX Series router, the configuration can be saved in configuration mode as a sequence of configuration commands on the router using the “show | display set | save <filename>” command and then copying the <filename> to the PC or router as juniper-config.txt.
  2. Copy the juniper-config.txt file to a Disk-on-Key device.
  3. Plug the Disk-on-Key device into the USB port on the new ACX Series router.
  4. Power on the router by pressing the POWER button on the front panel. Wait for the router to start and access the Disk-on-Key device (observe the LEDs on the Disk-on-Key device).

    The router reads the juniper-config.txt file from the Disk-on-Key device and commits the configuration.

  5. Remove the Disk-on-Key device from the router.
  6. The configuration of the router is complete.
