i noticed that the 1242AG does not bring up the Radios, when there is a Power Injector connected.
I see in the Logs of the AP:
%CDP_PD-2-POWER_LOW: All radios disabled - NEGOTIATED WS-C6509 <Switchport MAC Add>
The Module in the 6500 is a WS-X6348-RJ-45
The Option "Power Injector installed" on the WLC is also enabled, with the MAC Address from the Switchport, but no change.
When i disable CDP on the mentioned Switch Port and reload the AP, it comes up and runs fine.
Any ideas, what is causing this problem?
Isn't there another option on the wlc in regards to the power. IIRC, there are two options, try checking the other option.

Is this the only WAP that's having a problem or are there more.
If this is the only WAP then check your cables.
