The Gigabit PoE Injector, model TPE-115GI, combines electrical power with a Gigabit network connection to produce a Gigabit Power over Ethernet Plus (PoE ) signal. Connect this device to a non-PoE Gigabit switch and then run an Ethernet cable for up to 100 meters (328 ft.) to network PoE or PoE devices. The integrated power supply reduces installation clutter. Auto sensing technology delivers 30 Watts to 802.3at PoE devices or 15 Watts to 802.3af PoE devices. No need to buy a PoE switch-use an existing open port from a non-PoE switch to save installation and equipment costs when installing TRENDnet PoE access points and IP cameras in remote locations.
