PoE Pins

XPort AR is PoE-ready; it allows a fully compliant PoE circuit to be implemented that uses the
Ethernet signals entering the XPort AR's RJ-45 jack. When the XPort AR's RJ-45 jack is
connected to a PoE compliant switch, pins 21, 22, 25, and 26 pass through the necessary
Ethernet signals to allow a PoE powered-device circuit to negotiate and receive power from
the switch.
