Hello, Can this Aircube AC be operated via PoE, i.e. where should the PoE Ethernet cable of the downstream switch be plugged in? It says PoE Out on the WAN port. I would like to use the Aircube as a normal AP that is supplied via PoE and not via the DC supplied. E.g. the PoE would be supplied by an EdgeSwitch 10XP or Ubiquiti EdgeSwitch XP ES-8XP, would this be possible?
