Upgrading the Firmware

Firmware images are bundled with ExtremeXOS and Switch Engine software images. The bundled firmware images include system FPGA and PLD images. When you download and install a new version of ExtremeXOS, ExtremeXOS automatically compares the existing firmware image against the firmware images bundled with the ExtremeXOS image, and prompts to install the firmware if there is a new version. If the firmware install is skipped during an ExtremeXOS install, firmware can be installed later by following the procedure below using the install firmware command.

After a firmware image upgrade, messages are sent to the log.

To view the current firmware version, use the show version detail command:

# show version detail

              FPGA: 1.1.34 CPLD: 1.1.13

  1. To install the firmware bundled with the ExtremeXOS image, use the install firmware {force} {slot slot-number} command.

    If the bundled firmware image is newer than the existing firmware image, the switch prompts you to confirm the upgrade.

  2. At the prompt:
    • Type y to upgrade the firmware.
    • Type n to cancel the firmware upgrade for the specified hardware, and continue scanning for other hardware that needs to be upgraded.
  3. Press Enter to cancel the upgrade.
    During the firmware upgrade, the switch also prompts you to save your configuration changes to the current, active configuration.
  4. To save your configuration changes to the current, active configuration, type y or to discard your changes, type n.
    The new firmware overwrites the older version.
You must reboot the switch to load the newly installed firmware. However, you do not need to do this immediately after a firmware upgrade. Use the reboot command to reboot the switch and activate the new firmware. During the firmware upgrade, do not turn off or disrupt the power to the switch. During the firmware upgrade, do not cycle down or disrupt the power to the switch. If a power interruption occurs, the installed firmware may be corrupted. In this case, the switch uses a backup version, and you can run the upgrade again to install the latest version.
