We just purchased an Air-AP2802i-B-K9. I am having an issue connecting it to our WLC 5508. We are running software version 184.108.40.206. On the access point it is flashing red-green-off. I checked the switch the AP is connected to and it shows up in CDP and the power on the port is pushing 26.3W. My question is do I need to upgrade our software on the WLC to accommodate the 2802i or is there something else I'm missing here.
I agree with Jurgens. The controller is running a version which doesn't support the model of AP. Upgrade the firmware of the controller to 8.2.X.X (or later). Please read the Release Notes carefully before doing any upgrades.
