TRENDnet's Gigabit PoE+ injector, model TPE-147GI, allows users to add PoE+ power to a non-PoE switch. Connect the 4-port PoE+ injector to a non-PoE Gigabit switch, and then run Ethernet cables to network four PoE devices. This multi-port Gigabit PoE+ injector supplies power to four PoE or PoE+ devices. The fanless design on the 4-port PoE+ injector conveniently eliminates operating noise and lowers energy consumption.
