PoE Injector Grandstream Networks POE-INJ

The Grandstream Networks POE-INJ is a Gigabit Ethernet PoE injector that delivers 48 V power while maintaining high-speed data transfer. Designed for use with Grandstream GWN76XX series devices and other PoE-capable equipment, this compact black injector provides a simple way to add remote power to access points, IP phones, cameras or other network endpoints without a nearby power outlet.

Advantages

The injector supports Gigabit Ethernet data rates and supplies 48 V PoE to connected devices through an RJ-45 port. Its compact black housing allows discreet placement in rack or shelf installations, and the two Ethernet ports separate data and PoE output for straightforward cabling. The device is compatible with standard PoE-powered equipment and is intended to provide reliable power delivery for network devices requiring 48 V.

How to use

Connect the injector's input Ethernet port to your network switch or router using a Cat5e/Cat6 cable, then connect the output RJ-45 port to the PoE device (access point, camera, or phone). Plug the injector into mains power. The injector will supply 48 V over the Ethernet cable to the connected PoE device while allowing data traffic to pass through at Gigabit speeds. Ensure cables and connected devices support the required power and data rates.

Usage recommendations

Use certified Ethernet cables (Cat5e or higher) and confirm that the powered device accepts 48 V PoE. Install the injector in a well-ventilated location away from moisture. For installations in the UK, ensure mains plugs and wiring comply with local regulations and safety standards.
