UltraPoE POE-M921 60W Gigabit 4-Pair PoE++ Injector
Add up to 60 W of 4-pair PoE power to a Gigabit Ethernet connection for high-power cameras, wireless access points and other compatible powered devices.
The UltraPoE POE-M921 is a single-channel Gigabit PoE injector with an internal AC/DC converter. It combines data from a non-PoE switch with power from a universal 100–240 VAC source, then sends both through one PoE/DATA cable.
Key Features
- 60 W 4-pair output: supplies up to 60 W through all four Ethernet pairs.
- Gigabit Ethernet: supports 10/100/1000Base-T applications.
- PoE device compatibility: supports IEEE 802.3af, IEEE 802.3at and compatible 4-pair powered devices.
- Universal AC input: 100–240 VAC, 50/60 Hz.
- Integrated converter: no separate external power brick required.
- Automatic device detection: identifies compatible PoE equipment before applying power.
- Status LEDs: indicators for AC power and powered-pair modes.
- Plug-and-play installation: supports Ethernet channel lengths up to 100 m.

Frequently Asked Questions
What does the POE-M921 do?
It adds power to a standard Gigabit Ethernet data connection so a compatible powered device can receive data and power through one cable.
Does it support Gigabit Ethernet?
Yes. It supports 10/100/1000 Mbps data transmission.
How much PoE power can it provide?
The user port supports up to 60 W over four pairs. Actual delivered power depends on the powered device, cable length and cable quality.
Does it require an external power brick?
No. The AC/DC conversion is built into the injector enclosure.
Is it the same as the 90 W POE-M931?
No. The POE-M921 is the 60 W model. Choose the POE-M931-90W when the powered device specifically requires a higher 90 W PoE budget.
