For the FTB ecosystem products, the EXFO Software Update (ESU) utility will check for updates on a cloud server and download/upgrade automatically. The ESU utility is installed on all recent FTB platforms. If you have an older unit, you can download ESU from EXFO’s website. If the ESU utility is already available on your test unit, simply connect it to the network and launch the ESU application. In three clicks, you will have your unit quickly updated with the latest software/firmware.
