## Summary description

The StarTech.com 4-Port Gigabit Midspan PoE+ Injector supports IEEE 802.3 standards and provides up to 120 W power. It features a compact design with a steel housing and LED indicators for PoE and power status. Ideal for powering devices over Ethernet up to 100 m away.

## Long description

The StarTech.com 4-Port Gigabit Midspan PoE+ Injector (POEINJ4G) supplies up to 30.8 W per port and a total of 120 W, enabling you to power and connect up to four PoE-compliant devices — such as IP cameras, wireless access points or VoIP phones — using standard Ethernet cabling. The compact steel housing with LED status indicators supports installation on a desk or wall and provides a cost-effective alternative to replacing a non-PoE network switch.
Advantages
This midspan PoE+ injector supports IEEE 802.3at/af standards and automatically detects the power requirements of connected powered devices, delivering the appropriate power level without risk of damage. It offers up to 30.8 W per port and 120 W total power distribution, integrated circuit protection between ports, plug-and-play operation, and a compact rugged metal case with LEDs for PoE and power status. The unit is suitable for extending PoE power up to standard Ethernet distances without needing dedicated AC outlets at device locations.
Suitable for
Powering IP cameras at remote locations
Supplying wireless access points that require PoE+
Connecting VoIP/IP phones to non-PoE switches
Adding PoE power to mixed networks without replacing the switch
Key specifications
Model: POEINJ4G (StarTech.com)
Ports: 4 x Gigabit Ethernet PoE+ ports
PoE standard: IEEE 802.3at/af
Power per port: up to 30.8 W
Total available power: 120 W
Casing: compact steel housing, wall-mountable
Indicators: PoE and power LEDs
How to use
Connect the injector to a non-PoE switch or other data source using a standard Ethernet cable, then connect your PoE devices to the injector’s PoE output ports with Cat5e/Cat6 cables. Plug the injector into AC power and verify the PoE and power LEDs indicate normal operation. The unit will automatically negotiate and supply the correct power level to each connected device.
Usage recommendations
Install the injector within 100 m of each PoE device using appropriate Ethernet cabling (Cat5e or better). Use surge protection where lightning or unstable power is a concern, and avoid overloading the total 120 W budget by checking device power requirements before connecting multiple high-power PDs.
