Barracuda Web Filter Release 3.3
50 Chapter 3: Configuring, Monitoring, and Managing the Barracuda Web Filter
Rebooting the system in recovery mode
If your Barracuda Web Filter experiences a serious issue that impacts its core functionality, you can
use diagnostic and recovery tools that are available at the reboot menu to return your system to an
operational state.
Before you use the diagnostic and recovery tools, do the following:
• Use the built-in troubleshooting tools on the
ADVANCED > Troubleshooting page to help
diagnose the problem.
• 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 Web Filter and run a memory test or perform a
complete system recovery, as described in this section.
To perform a system recovery or hardware test:
1. Connect a monitor and keyboard directly to your Barracuda Web Filter.
2. Reboot the system by doing one of the following:
• In the Web interface: Go to the
BASIC > Administration page, navigate to the System
Reload/Shutdown section, and click
Restart.
• At the front panel of the Barracuda Web Filter: Press the Power button on the front panel to
turn off the system, and then press the Power button again to turn the system on.
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 the Enter key.
You must select the boot option within three seconds after the splash screen appears. If you do
not select an option within three seconds, the Barracuda Web Filter starts up in Normal mode
(first option).
For a description of each boot option, refer to Reboot options on page 51.
Note:
To stop a hardware test, reboot your Barracuda Web Filter by pressing the Ctrl-Alt-Del
keys.
