How to Restore a Configuration on Appliances After an RMA

  • Last updated on

The following article describes how to restore a configuration backup (PAR file) on a Barracuda NG Firewall appliance with another hardware revision model. This is necessary if your appliance is replaced with a newer revision model of the same product type. E.g.: F400 Rev. A and F400 Rev. B. This typically occurs in RMA cases if your appliance is replaced by Barracuda's hardware refresh program.

General

Before you can restore a new Barracuda NG Firewall unit, a configuration backup of the production unit must be created. The backup can then be used to restore the current configuration on a new hardware unit. For information on how to back up and restore configurations, see Backups and Recovery. After restoring the configuration on the new NG Firewall unit, the Hardware Model must be adjusted to match the appliance revision of the new unit. This is necessary because different hardware models typically come with newer network interfaces and thus require appropriate drivers. If the hardware model is not set correctly, the network modules may not be available after restoring the appliance.
