Status Managing the FortiLog unit
The FortiLog unit saves the backup firmware image and restarts. When the FortiLog
unit restarts it is running the previously installed firmware version.
Switching to a backup firmware image
Use this procedure to switch the FortiLog unit to operating with a backup firmware
image that you previously installed. When you switch the FortiLog unit to the backup
firmware image, the FortiLog unit operates using the configuration that was saved with
that firmware image.
If you install a new backup image from a reboot, the configuration saved with this
firmware image is the factory default configuration. If you use the procedure
“Switching to the default firmware image” on page 38 to switch to a backup firmware
image that was previously running as the default firmware image, the configuration
saved with this firmware image is restored.
To switch to the backup firmware image
1 For all three FortiLog models, use a terminal emulation software to access the unit’s
CLI.
For the FortiLog-800 unit, you can also access the unit’s CLI by connecting the
null-modem cable provided to the unit’s console port.
2 Enter the following command to restart the FortiLog unit:
execute reboot
As the FortiLog unit starts, a series of system startup messages are displayed.
When the following message appears:
Press any key to enter configuration menu.....
3 Immediately press any key to interrupt the system startup.
If you successfully interrupt the startup process, the following message appears:
[G]: Get firmware image from TFTP server.
[F]: Format boot device.
[B]: Boot with backup firmware and set as default.
[Q]: Quit menu and continue to boot with default firmware.
[H]: Display this list of options.
Enter G,F,B,Q,or H:
4 Type B to load the backup firmware image.
The FortiLog unit loads the backup firmware image and restarts. When the FortiLog
unit restarts, it is running the backup firmware version and the configuration is set to
factory default.
Switching to the default firmware image
Use this procedure to switch the FortiLog unit to operating with the backup firmware
image that had been running as the default firmware image. When you switch to this
backup firmware image, the configuration saved with this firmware image is restored.
Note: You have only 3 seconds to press any key. If you do not press a key soon enough, the
FortiLog unit reboots and you must log in and repeat the
execute reboot command.
