The update is a very straight forward process that can be done entirely through the OA web administration interface.
Go to Active Onboard Administrator –> Firmware Update.
From that screen you can upload the firmware from your system or enter an URL where the image is available. For our example we are going to use the upload option. Browse to the firmware image file and click Upload.
The OA web administration interface will logout any connected user and will start the upgrading process.
During the upgrade a progress bar like the one in the above screenshot will be shown and the OA will be reset when the process is complete.
Finally log into the OS and from the Active Onboard Administrator screen check the OA version.
