For Extreme Networks industrial switches, the POE INJ-75W-24 is a single-port passive PoE injector that provides maximum 75W power over CAT5 or 5e UTP/STP Ethernet cable by four pairs. The POE INJ-30W-24 is a single-port PoE inject or that complies with IEEE802.3at/ af and provides maximum 30W power over CAT5 or 5e UTP/STP Ethernet cable by two pairs.
The injectors support two redundant DC inputs from 20 VDC - 60 VDC for industrial backup. You can connect the PoE injectors to Ethernet-powered devices, such as wireless APs, pan-tilt-zoom (PTZ) speed dome cameras, IP videophones, and other high-power Ethernet end terminals. These terminals must allow the PoE injector to deliver both data and power over an Ethernet cable in an industrial environment.
