Read Before Updating

  • Before installing any firmware version, back up your configuration and read all release notes that apply to versions more recent than the one currently running on your system.
  • Before upgrading a virtual machine, it is highly recommended to take a snapshot of that virtual machine.
  • Do not manually reboot your system at any time during an update unless otherwise instructed by Barracuda Technical Support. Depending on your current firmware version and other system factors, updating can take up to 10 minutes. If the process takes longer, contact Barracuda Technical Support for further assistance.

Known Issues

  • The SSL hardware is now disabled by default in the Barracuda Load Balancer ADC 640 and 840. The administrator can enable the SSL hardware functionality if required.
