How to Update the Firmware

  • Last updated on

Applying a new firmware version results in a short service outage.

The Firmware Update page allows you to manually update the firmware version of the system or revert to a previous version. You should only revert to an old firmware version if your recently downloaded new version causes unexpected problems. Always contact Barracuda Networks Technical Support before reverting to a previous firmware version.

Do not manually power-cycle the Barracuda Link Balancer at any time during the update process because it can cause firmware corruption.
