  • Delivers up to 90 W over four pairs with auto-detection
  • Backward compatible with 802.3af and 802.3at legacy PoE devices
  • Silent fan-less design suits noise-sensitive environments
  • Single-port mid-span injector mounts on desktop or surface
  • Plug-and-play installation requires no configuration

Single-port 90W PoE++ injector

The EnGenius EPA5090GBT is a single-port midspan injector that delivers up to 90W over four pairs to power IEEE 802.3bt Type 3 and 4 devices. It supports 10/100/1000 Mbps data rates and remains backward compatible with 802.3af and 802.3at equipment. A fan-less enclosure provides silent operation for desktop or surface-mount placement. Plug-and-play installation requires no configuration.

Installers adding PoE to non-PoE switches

Network technicians who need to power high-draw access points, cameras or LED lighting from an existing non-PoE switch will find this injector matches the 802.3bt Type 3 and 4 standard. It is not suited for deployments that require multi-port power distribution or managed PoE features such as scheduling or per-port priority. Buyers needing to power many devices from one unit should consider a full PoE switch instead.

90W four-pair power budget

The injector supplies a maximum of 90W across all four twisted pairs with automatic detection of the connected device’s power class. This single figure determines whether a specific 802.3bt Type 3 or Type 4 endpoint can be powered without an additional source.

Questions about this item

What IEEE 802.3bt type does the EPA5090GBT support and what power level does that cap at?

It complies with IEEE 802.3bt Type 3 and Type 4, delivering up to 90 W over four pairs.

What mounting options does the single-port midspan injector provide?

The flexible design allows desktop placement or surface mounting without additional brackets.

How is the injector installed and which step do users often miss?

Connect the injector between the switch and the powered device using Ethernet cables; the step often missed is verifying that the PD negotiates the required 802.3bt class before applying full power.
