Tasks to Perform Before Rebooting in Recovery Mode
Before you use the diagnostic and recovery tools, perform the following tasks:
Use the built-in troubleshooting tools to help diagnose the problem. For more information, see
Troubleshooting on page 104.
Perform a system restore from the last known good backup file.
Contact Barracuda Networks Technical Support for additional troubleshooting tips.
• As a last resort, you can reboot your Barracuda Spam Firewall and run a memory test or perform
a complete system recovery, as described in this section.
Performing a System Recovery or Hardware Test
To perform a system recovery or hardware test:
1. Connect a monitor and keyboard directly to your Barracuda Spam Firewall.
2. Reboot the system by doing one of the following:
• Clicking the
Restart button on the Basic > Administration page.
• Pressing the Power button on the front panel to turn off the system, and then pressing the
Power button again to turn back on the system.
The Barracuda splash screen displays with the following three boot options:
Barracuda
Recovery
Hardware_Test
3. Use your keyboard to select the desired boot option, and press Enter.
You must select the boot option within three seconds of the splash screen appearing. If you do
not select an option within 3 seconds, the Barracuda Spam Firewall defaults to starting up in the
normal mode (first option).
For a description of each boot option, refer to Reboot Options on page 109
Reboot Options
The following table describes the options available at the reboot menu.
Note
Reboot your Barracuda Spam Firewall to stop the hardware test.
