FortiGate Firmware
Fortinet periodically updates the FortiGate firmware to include enhancements and
address issues. After you have registered your FortiGate unit, FortiGate firmware
is available for download at http://support.fortinet.com.
Only the FortiGate administrators (whose access profiles contain system
configuration read and write privileges) and the FortiGate admin user can change
the FortiGate firmware.
This section includes the following topics:
• Upgrading to a new firmware version
• Reverting to a previous firmware version
• Installing firmware images from a system reboot using the CLI
• The FortiUSB key
• Testing a new firmware image before installing it
• Installing and using a backup firmware image (FortiGate-100 only)
Upgrading to a new firmware version
Use the web-based manager or CLI procedure to upgrade to a new FortiOS
firmware version or to a more recent build of the same firmware version.
Upgrading the firmware using the web-based manager
Use the following procedures to upgrade the FortiGate unit to a new firmware
version.
To upgrade the firmware using the web-based manager
1 Copy the firmware image file to your management computer.
2 Log into the web-based manager as the admin administrative user.
3 Go to System > Status.
4 Under System Information > Firmware Version, select Update.
Note: If you have an earlier version of the FortiOS firmware, for example FortiOS v2.50,
upgrade to FortiOS v2.80MR11 before upgrading to FortiOS v3.0.
Note: Installing firmware replaces your current antivirus and attack definitions, along with
the definitions included with the firmware release you are installing. After you install new
firmware, make sure that antivirus and attack definitions are up to date. For details see the
FortiGate Administration Guide.
Note: To use this procedure, you must log in using the admin administrator account, or an
administrator account that has system configuration read and write privileges.
