Just starting out with our new 2106 controller and 3 1252's. I have PoE injectors on the AP's (AIR-PWRINJ4), but I get the same problem if I plug in to the WLC ( i know its not enough power, just trying it out).
All I seem to get are all lights flashing on 2 of the AP's I have tried. The closest diagnostic I can pull out of the troubleshooting table online is that there isn't enough power. The lights are as follows:
Ethernet blinking Green
Status Blinks green, blue, red (power issue?)
Radio blinks amber
Again, there really isn't a chart that says what this problem could be, I am just going off of the status code. I logged in the console and ran debug lwapp events enable and see nothing...
Well for one, the power injector you are using is correct for the 1252. That will power both radios up. The problem you see is the LAP not joining the wlc. You have to configure the 2106 and then have the 1252 join the wlc and you will be good to go.
