Upgrading from FortiAP-U version 5.4.6

FortiAP-U version 6.0.0 supports upgrading from FortiAP-U version 5.4.6.

Upgrading FAP-U431F/433F trial version firmware

Some FAP-U431F and FAP-U433F devices come preinstalled with the trial version firmware "FortiAP-U431F v6.0,build0000" or "FortiAP-U433F v6.0,build0000". FortiAP-U devices running trial version firmware are not supported by FortiGate. To upgrade from the trial version firmware to the latest supported version, you must disable the third radio of your FAP-U431F and FAP-U433F devices.

To upgrade your FAP-U431F and FAP-U433F devices

1. Connect your FAP-U431F and FAP-U433F devices to a FortiGate running FortiOS version 6.2.2.
2. Log in to the FortiGate web UI and go to WiFi & Switch Controller > Managed FortiAPs.
3. Locate your discovered FAP-U431F and FAP-U433F devices and then authorize them.

4. Access the FortiGate CLI and edit the wtp-profile of your FAP-U431F or FAP-U433F devices to disable the third radio.

   For example:

   config wireless-controller wtp-profile

   edit FAPU431F-default

   config radio-3

   set mode disabled

   end

   end

5. Go to the Fortinet Support website to download the latest supported FortiAP-U firmware files to your local disk.
6. Go to WiFi & Switch Controller > Managed FortiAPs and select the FAP-U431F or FAP-U433F devices you want to upgrade.

7. Right-click and select Upgrade from the context menu.

   The Upgrade FortiAPs window loads.

8. Click Browse and select the appropriate firmware file from your local disk, and click Upgrade.

   The FAP-U431F or FAP-U433F devices upgrade to your selected firmware. When the upgrade is complete, the FortiAP status changes to "Online".

9. After the FortiAP-U firmware is upgraded, you can re-enable the third radio of your FAP-U431F or FAP-U433F devices.
