Usage Guidelines

On the ExtremeSwitching 5520 switch, use the install firmware command to upgrade the system FPGA and PLD images.

Firmware images are bundled with ExtremeXOS software images.

On the ExtremeSwitching 5520 switch, the ExtremeXOS software automatically compares the existing firmware image flashed into the hardware with the firmware image bundled with the ExtremeXOS image. You can also use the install firmware command to compare the firmware images.

Before using the install firmware command in a stack, wait until the show slot command indicates the slots are operational. When the slots are operational, use the install firmware command.

The switch checks internal devices for a possible firmware upgrade. If the bundled firmware image is newer than the existing firmware image, the switch prompts you to confirm the upgrade.

Enter y to upgrade the firmware.
Enter n to cancel the firmware upgrade for the specified hardware and continue scanning for other hardware that needs to be upgraded.
Enter _cr to cancel the upgrade. After a firmware image upgrade, messages are sent to the log.

The new FPGA and PLD firmware overwrites the older versions flashed into the hardware. The switch always maintains a backup version in hardware in case the install is interrupted. Use the reboot command to reboot the switch and activate the new firmware.

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.

The switch displays status messages after you use the install firmware command. The output varies depending upon your platform and the software version running on your system.

During a firmware upgrade, the switch prompts you to save your configuration changes to the current, active configuration. Enter y to save your configuration changes to the current, active configuration. Enter n if you do not want to save your changes.

PoE firmware is always automatically upgraded or downgraded to match the operational code image. This configuration is not applicable to PoE firmware.
