Extend PoE to the devices that need it without rebuilding the access layer. The StarTech POEINJ4G-US is a 4-port Gigabit PoE+ midspan injector designed to deliver data and power to four PoE-powered devices from a standard non-PoE switch. Supporting both IEEE 802.3at and 802.3af, it gives infrastructure teams a clean way to add powered connectivity for access points, IP cameras, and VoIP phones where replacing the switch would add cost and downtime. Each port can deliver up to 30.8 watts, giving you enough headroom for higher-demand endpoints while keeping deployment simple. The wall-mountable, desktop-sized design fits neatly into closets, kiosks, and distributed edge locations. Plug-and-play operation reduces setup time, while automatic PoE detection supplies the proper power level to connected PDs. For teams standardizing on existing Gigabit switching, this injector preserves the current network investment and adds PoE only where it is needed.
