1 Gigabit Ethernet port input and 1 PoE+ Gigabit Ethernet port output offer full duplex 2Gbps Ethernet speeds. Auto-sensing technology delivers up to 802.3at 60W to a PoE+ device with backwards compatibility for 802.3at(30w) and 802.3af PoE (15.4W) devices. Not support 802.3 bt/PoE++ or any passive PoE devices. Converts a non-PoE Gigabit port to a PoE+ Gigabit port and Network a PoE device located up to 100 meters (328 ft.) away. Plug & play, no configuration is needed, simply connect a PoE network device, accommodates most installations scenarios. High Performance Gigabit PoE/PoE+ injector, IEEE 802.3af/802.3at compliant. Pin Assignment and Polarity: 1/2 (-), 3/6 (+),4/5(+), 7/8(-)
