Using Cisco 3800 series AP(s) and Power

!Pro Tip – Always look at the data sheet

So I was labbing up a Cisco 3802i AP to test some changes for a Change Control submission and ran into an issue with the 3802i AP. Since I didn’t connect the AP, I didn’t think about until I got back to my office from the lab to start working on the testing. The AP Radios were operationally down. Since this is a new environment, I had to dig into the issue a bit before I determined that the issue was the POE Injector used in the lab.

Cisco 3802i AP(s) require 802.11at power which maps to a Cisco AIR-PWRINJ6. If you use a AIR-PWRINJ5 the radios will not come up.

Zach mentioned that the AP will also give a visual cue with the LED lights!

Now I need to order some AIR-PWRINJ6 power injectors for the lab….and my Tech Bag. 🙂
