Fortinet FortiLog-400, FortiLog-100, FortiLog-800 manual Switching to a backup firmware image

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.
