Description

StarTech POEINJ4G 4-Port Gigabit PoE Injector Hub

Overview

The StarTech POEINJ4G is a 4-port Gigabit PoE injector hub designed to deliver both network data and up to 30.8W of PoE power to four separate Power Devices (PD) over a single Ethernet cable. This unit consolidates power and data delivery, simplifying installations for IP cameras, wireless access points, or VoIP phones where running separate power and data lines is impractical. Its compact, wall-mountable steel chassis is suitable for deployment in network closets or near endpoints.

Compatibility

This injector hub is compatible with any IEEE 802.3at or 802.3af compliant Power Device (PD). It supports devices requiring up to 30.8W per port, covering most standard PoE cameras, access points, and phones. The Gigabit Ethernet ports ensure full 1000 Mbps throughput for each connected device, preventing bandwidth bottlenecks common with older Fast Ethernet injectors.

Installation Notes

The POEINJ4G operates within a 0°C to 50°C (32°F to 122°F) ambient temperature range. It requires a 100-240V AC input, converting it to 54V DC output. Maximum cable length for reliable operation is 100 meters (328 ft). The unit is constructed from steel for durability.
