PoE Injector Grandstream GS-POE30W-MG 30W Ethernet PoE Injector for Network Devices

The Grandstream GS-POE30W-MG 30W Ethernet PoE Injector supplies power and data over a single Ethernet cable to compatible PoE devices. This compact, single-port injector is designed to deliver up to 30 watts of power to IP phones, wireless access points and other PoE-capable network equipment. The unit simplifies installations in locations without convenient power outlets and provides a straightforward way to add PoE capability to existing Ethernet cabling without replacing switches.

Advantages

The injector combines data transmission and power delivery in one cable, reducing cable clutter and installation complexity. Its compact form factor allows for flexible placement near devices or network wiring closets. Built to be compatible with standard PoE devices, it offers reliable power delivery up to 30W and plug-and-play operation without special configuration. The device supports stable operation for small deployments and point installations where a single PoE feed is required.

Suitable for (tasks / use cases)

• Powering IP desk phones and conference phones in office or branch locations
• Supplying power to wireless access points in ceilings or walls where outlet access is limited
• Feeding single PoE cameras or small network devices in point installations
• Adding PoE capability to existing Ethernet drops without replacing non-PoE switches

Key specifications

• Maximum power output: 30 watts
• Port configuration: single data+power output port and one data input port
• Power delivery: IEEE-compatible PoE power delivery up to 30W
• Data interface: 10/100/1000 Mbps Ethernet compatible
• Form factor: compact inline injector for desktop or wiring-closet mounting
• Power source: external AC power input to the injector

How to use

Connect the injector's data input port to a network switch or router using a standard Ethernet cable, then connect the PoE-enabled device to the injector's data+power output port with a second Ethernet cable. Plug the injector into a nearby AC outlet to provide power. The device operates without configuration; once connected and powered, it will supply up to 30W to the connected PoE device. Verify that the powered device supports PoE and that its power requirements do not exceed the injector's 30W output.

Recommendations

Place the injector in a ventilated location away from direct heat sources. Use quality Ethernet cables (Cat5e or higher) for optimal power and data delivery. Check device compatibility and power requirements before connection to avoid overload. If deploying multiple devices, consider a PoE switch or distribution solution for centralized power management.
