Maintenance 101
Updating the Definitions from Energize Updates
The
ADVANCED > Energize Updates
page allows you to manually update the Virus, Application and
Security Definitions used on your Barracuda SSL VPN, as well as change the interval at which the
Barracuda SSL VPN checks for updates.
We recommend that the
Automatically Update
setting be set to
On
so your Barracuda SSL VPN
receives the latest rules as soon as they are made available by Barracuda Central.
Replacing a Failed System
Before you replace your Barracuda SSL VPN, use the tools provided on the
ADVANCED >
Troubleshooting
page to try to resolve the problem.
In the event that a Barracuda SSL VPN fails and you cannot resolve the issue, customers that have
purchased the Instant Replacement service can call Barracuda Networks Technical Support and
arrange for a new unit to be shipped out within 24 hours.
After receiving the new system, ship the old Barracuda SSL VPN back to Barracuda Networks at the
address below with an RMA number marked clearly on the package. Barracuda Networks Technical
Support can provide details on the best way to return the unit.

Reloading, Restarting, and Shutting Down the System
The
System Reload/Shutdown
section on the
BASIC > Administration
page allows you to shutdown,
restart, and reload system configuration on the Barracuda SSL VPN.
Shutting down the system powers off the unit. Restarting the system reboots the unit. Reloading the
system re-applies the system configuration.
You can also perform a hard reset of the Barracuda SSL VPN by pressing the
RESET
button on the
front panel of the system. Caution should be used when pressing the reset button, however, since
doing so while the Barracuda SSL VPN is in the midst of a configuration update or other task can
result in inadvertent corruption of the system.
Using the Built-in Troubleshooting Tools
The
ADVANCED > Troubleshooting
page provides various tools that help troubleshoot network
connectivity issues that may be impacting the performance of your Barracuda SSL VPN.
Note
To set up the new Barracuda SSL VPN so it has the same configuration as your old failed system,
first manually configure the new system’s IP information on the
BASIC > IP Configuration
page,
and then restore the backup file from the old system onto the new system. For information on
restoring data, refer to
Backing up and Restoring Your System Configuration on page 100.
