  • Last updated on

To recover the Barracuda CloudGen Firewall F-Series, format a USB flash drive and import the CloudGen Firewall F-Series ISO image to the drive. You can also include PAR/PCA files and hotfixes. If you are including a PCA file, verify that the password for the PCA file is set to the serial number of your hardware appliance. If you include hotfixes, they are installed in alphabetical order after the firmware in the post-install section. A reboot is required after hotfix installation.
