If the connection to the FDN or override server is successful, the web-based manager
displays a message similar to the following:
Your update request has been sent. Your database will be updated
in a few minutes. Please check your update page for the status
of the update.
After a few minutes, if an update is available, the System Update Center page lists
new version information for antivirus definitions, the antivirus engine, attack definitions
or the attack engine. The System Status page also displays new dates and version
numbers for antivirus and attack definitions. Messages are recorded to the event log
indicating whether the update was successful or not.

2 Select the Scheduled Update check box.

Whenever the FortiGate unit runs a scheduled update, the event is recorded in the
FortiGate event log.
To add an override server
If you cannot connect to the FDN, or if your organization provides antivirus and attack
updates using their own FortiProtect server, you can use the following procedure to
add the IP address of an override FortiProtect server.
1 Go to System > Maintenance > Update center.
2 Select the Use override server address check box.
3 Type the fully qualified domain name or IP address of a FortiProtect server.
Note: Updating antivirus and attack definitions can cause a very short disruption in traffic
currently being scanned while the FortiGate unit applies the new signature database. To
minimize this possibility, schedule updates for times of light traffic.
Every Once every 1 to 23 hours. Select the number of hours and minutes between
each update request.
Daily Once a day. You can specify the time of day to check for updates.
Weekly Once a week. You can specify the day of the week and the time of day to check
for updates.
