[POE] Tibbits That Require PoE Power Lines

Tibbit #23 implement PoE (power-over-Ethernet) power supplies. By definition, PoE power comes from the Ethernet cable. Therefore, PoE Tibbits must be wired in such a way as to receive PoE power input from the RJ45 jack.

TPP2 and TPP3 both have a single socket which can receive PoE power.
