This example verifies the current version of FortiOS firmware and, if necessary, updates it to the latest version.

FortiOS is the operating system used by FortiGate and FortiWiFi units. You can update FortiOS to use of the latest tools and security features available.

Warning: Always review the Release Notes and Supported Upgrade Paths documentation before installing a new firmware. These documents can be found at the Fortinet Document Library.

This recipe is only for FortiOS 5.2.1 and earlier. For instructions for later releases, go here.

1. Checking the current FortiOS firmware

Log in to the GUI and go to System > Dashboard > Status and view the System Information dashboard widget to see the Firmware Version currently installed on your FortiGate unit.

Go to the Fortinet Document Library and refer to the Release Information section to determine the most recent version of FortiOS.

2. Downloading the latest FortiOS firmware

To download a new firmware version, browse to Fortinet Support and log in using your Fortinet account ID/email and password.

 

Go to Download > Firmware Images. 

From the Select Product drop down menu, choose FortiGate.

Locate and download the firmware for your FortiGate model. 

3. Updating the FortiGate to the latest firmware

Go to System > Dashboard > Status.

Backup your configuration from the System Information dashboard widget, next to System Configuration. Always remember to back up your configuration before doing any firmware upgrades.

Under System Information > Firmware Version, select Update.

Find the firmware image file that you downloaded and select OK to upload and install the firmware build on the FortiGate unit.

4. Results

The FortiGate unit uploads the firmware image file, updates to the new firmware version, restarts, and displays the FortiGate login. This process takes a few minutes.

 

From the GUI, go to System > Dashboard > Status. In the System Information dashboard widget, the Firmware Version will show the updated version of FortiOS.
