The Cisco AIR‑PWRINJ5 is a compact, yet powerful PoE midspan injector designed for Cisco Aironet access points in environments where inline power is not available. This external power injector delivers up to 15.4 W of PoE (802.3af Type 1) over standard Category 5 or better Ethernet cable—enabling Wi‑Fi deployments in ceilings, ceilings, remote walls, and temporary locations without the need for local AC power outlets.
Equipped with two separate RJ‑45 ports (one for data input from a network switch, one for data + power output to the access point), the AIR-PWRINJ5 supports full gigabit throughput when used with a 10/100/1000 Mbps switch. The injector features a C14 power cord input and a single green LED that indicates both power availability and valid load detection—blinking for AC power, solid when powering a connected device, or rapidly blinking upon fault connection .
Built for simplicity, the unit includes mounting tabs for wall or tray installation and supports the full 100-meter Ethernet reach, including its built-in 2-meter cable—ideal for clutter-free, accessible deployments.

Why Choose Cisco AIR‑PWRINJ5?
We understand that making the right purchase decision is important. Below, you’ll find answers to common pre-sales questions about this product.
Cisco Aironet 1040, 1140, 1260, 1600, 2600, 3500, and 3600 Series (without modules)
No-this model supports up to 802.3af at 15.4 W; use PWRINJ6 for higher wattage.
Up to 100 m (328 ft) using Cat5e or better cable, including length of injector
No-do not stack or bundle the injector with its power cable to prevent overheating
Blinking green = AC good; solid green = powering AP; rapid blink = fault.
The injector includes built-in mounting tabs but screws are not provided.
0–40 °C operating; –20–70 °C storage
No-it is designed for indoor use only.
Yes-the standard C14 cable can be swapped for regional variants.
The LED will flash rapidly, indicating no power delivery until compatible load is found.
