TRENDnet's 65W 4-Port 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 up to 100 meters (328 ft.) to network four PoE devices. This multi-port gigabit PoE+ injector supplies up to 30W of power to four PoE or PoE+ devices. The fanless design on the 4-port PoE+ injector conveniently eliminates operating noise and lowers energy consumption.
