Boot and Initialize the SSR400 Routers

Use the following procedures to boot, initialize, and onboard your SSR400 Router.

Because the SSR400 routers do not have a power switch, each device powers up into the boot process when power is applied. You can apply power either by plugging an appliance into a live outlet or by operating an external power switch.

For a manual upgrade, copy the new image to a USB drive and insert the USB into the device prior to powering on the SSR400. Manual upgrade supports images later than 7.1.0. See Re-Installing SSR Software from a USB for more information.

Normal System Boot

To boot an SSR400 for the first time:

  1. Connect a terminal emulator to the front USB-C serial console port. The baud rate must be configured to 115,200bps. For more information, see Connect Your Device to a Management Console Using a USB-C Connector.

  2. Power the system on. The system LED flashes red to indicate a hardware reset is in progress.

    The system LED changes from red to amber, indicating the firmware boot is in progress.

    After 5 seconds, or if Esc is pressed, the system LED changes to green and then to amber to indicate an SSR software boot is in progress.

    Any time the system is rebooted, the firmware checks the system and compares it against the firmware capsule versions available on disk. Any required firmware updates are automatically installed. During this process, the system LED color changes to amber, indicating a firmware update is in progress.

    Note:

    The SSR can install multiple firmware updates with an automatic reboot after each individual update. Do not power cycle or interrupt the firmware update process.

    Subsequent boots skip previously installed updates.

    To indicate booting is in progress, the system LED changes from green to amber.

  3. After the OS boot has completed, the hardware bootstrapper runs. The system LED changes from green to teal twice during this activity. When the SSR software application is up and running, the system LED displays the following colors to indicate status:

    • Red: Error detected in the device.
    • Purple: Degraded service.
    • Steady Green: Device operating normally.

  4. After the system LED changes to green, initialize your device as either a Conductor-managed router or a Mist-managed router.

To initialize your router, connect your laptop to any of the designated LAN ports and connect to 192.168.128.1 to access the SSR Initialization workflow.

If you prefer to use the CLI, use the information provided in the Advanced Initialization Workflow.

Reinstall SSR Software from a USB

Use the following procedure to manually upgrade an SSR400 router using a USB drive. This procedure is most common in secure networks with no external internet connection, or in a case where the SSR400 is upgraded prior to deployment. Reinstallation deletes all configuration and settings, but does not perform a secure erase. Refer to the Factory Reset procedure to return to zero if necessary.

This procedure assumes you have already copied the SSR-7.1.x*.aarch64*.iso to a USB drive. For information about the procedure, see Creating a Bootable USB.

  1. Insert the USB drive with the new image into the USB-C port on the rear of the device.

  2. Power on the system.

  3. At the instruction in the terminal window: Press ESC for boot menu, press Esc to boot from the USB. The USB installer boots as follows:

  4. Press Enter or wait for the countdown timer to expire. The SSR OS installer boots:

    Once the installer has booted, the following menu is displayed:

  5. The default installation options for the SSR400 routers are shown above: FIPS enabled and cloud-init disabled. Press 1 or 2 to toggle the options if required. To start the installation, press Enter or wait for the countdown timer to expire. The system LED changes to teal, indicating the installation is in progress.

  6. You must manually reboot the system. Press Esc to reboot. You can press Enter to shut down the system; however, you must manually power cycle the system to perform the required reboot.

  7. After the OS boot has completed, the hardware bootstrapper runs. The system LED changes from green to teal twice during this activity. When the SSR software application is up and running, the system LED displays the following colors to indicate status:
    • Red: Error detected in the device.
    • Purple: Degraded service.
    • Steady Green: Device operating normally.
  8. After the system LED has changed from cyan to green or purple, initialize your device as either a Conductor-managed router or a Mist-managed router.

To initialize your router, connect your laptop to any of the designated LAN ports and connect to 192.168.128.1 to access the SSR Initialization workflow.

If you prefer to use the CLI, use the information provided in the Advanced Initialization Workflow.
