Maybe this would help you? Check the LAN switch part, maybe all LAN parts are part of one LAN switch? I am just guessing because I have no idea what has been done.

Also have you already updated the firmware? Put the latest image on an USB and reboot the unit.
It will go factory again but then you have a good start (otherwise use webinterface to update).
