Grandstream GS-POE-MG Series: Power and Connect Your Network Reliably
The Grandstream GS-POE-MG Series of Power over Ethernet injectors are the essential, cost-effective solution for powering network devices in locations far from electrical outlets. Whether you are installing a Wi-Fi access point on a high ceiling, positioning a security camera in a remote corner of a warehouse, or setting up a VoIP phone on a desk, these compact injectors simplify your installation.
Each injector in the GS-POE-MG series is a plug-and-play device that requires no configuration. It works by inserting itself between your existing network switch and the PoE-powered device (PD). The injector receives data from your switch, combines it with electrical power from its built-in AC adapter, and sends both over a single Ethernet cable to power and connect your device. Each model in the GS-POE-MG series includes a built-in power adapter with a generous 1.2m AC cable, eliminating desktop "wall warts" and messy cable adapters. The durable housing is designed to withstand the rigours of daily use and comes with an integrated Kensington lock slot and support for wall mounting with two wall-mount screw points (screws not included). Two LED indicators provide clear visual status: a blue Power On LED and a purple PoE Load LED that confirms the powered device is successfully connected.
Choose the Right Model for Your Device
The series offers three models, each tailored to different power and speed requirements:
-
GS-POE15W-MG (The Standard): A 15-20W injector that complies with the IEEE 802.3af (PoE) standard. It's the perfect match for basic IP phones, standard Wi-Fi 5/6 access points, and fixed security cameras with modest power needs. It features 2.5Gbps Ethernet pass-through ports, ensuring no network bottlenecks. The tradezone.com.au datasheet lists a PoE output power of 15W(final value may vary by region).
-
GS-POE30W-MG (The Upgrade): A 30W injector that complies with the higher-power IEEE 802.3at (PoE+) standard. It's ideal for more demanding devices, such as pan-tilt-zoom (PTZ) cameras, video conferencing hubs, and high-performance Grandstream GWN access points like the GWN7660E or GWN7672. Like the 15W model, it features a 2.5Gbps pass-through to maintain high-speed connectivity. It delivers a rated PoE output power of 30.2W.
-
GS-POE60W-MG (The High-Performance): The most powerful injector in the series, delivering up to 60W of power and compliant with IEEE 802.3bt (PoE++ / 4PPoE) standards. This is the correct choice for the most power-hungry devices, such as advanced PTZ cameras, digital signage, and high-performance Wi-Fi access points that require the maximum power budget. It stands apart with 10Gbps Ethernet pass-through, ensuring it is future-proof for the fastest network connections. It delivers a rated PoE output of 60W.

Frequently Asked Questions
Q1: What is the difference between a PoE injector and a PoE switch, and which should I use? +
A PoE switch has multiple ports and can power many devices at once. A PoE injector is a single-port device used to power just one device. In a small office with just one or two access points, the injector is a very cost-effective choice. For larger networks with multiple devices (like cameras or phones), you would normally use a PoE switch, but it is also perfectly acceptable to use a separate injector for each run.
Q2: How do I choose the correct power rating for my specific Grandstream device? +
A good rule of thumb is to choose an injector that meets or slightly exceeds the device‘s maximum rated power consumption. For example, if an AP needs 25W, you would select the 30W or 60W injector. For older phones that consume only a few watts, the 15W injector is sufficient. If in doubt, check your device’s datasheet. If you are unsure, choosing a higher-power model is always the safer bet because they are universally backward-compatible.
Q3: Is there any performance loss when using a PoE injector compared to a direct LAN connection? +
No, there should be no performance loss at all. A high-quality PoE injector, like the Grandstream GS-POE Series, simply injects power onto the Ethernet cable. The data signal passes through completely transparently and is not altered or degraded. You should get the exact same network speed and reliability as if your device were plugged directly into your router or switch.
Q4: Does the injector come with its own short Ethernet cables? +
No, the injector requires your own standard Ethernet cables. To minimise the number of cables, mount the PoE injector on the wall near your Power over Ethernet (PD) device, such as an Access Point. Then use a short patch cable to connect the injector‘s “PoE” port to your device (AP). A separate, longer cable is then run from the injector’s “LAN IN” port back to your network switch.
