I figured an RMA was in the near future on this one but I was just curious as to what might cause an AP to make noise like this.
The AP125's run VERY hot, I wouldn't be surprised if it's a melting component, most likely a capacitor. Low grade cap's will squeal like a banshee before it pops.

This unit clearly has a non-typical problem, and should be replaced and returned for analysis.

However, you might want to verify that the power injector or POE switch feeding it is sending the right voltage. If that's wrong, it could have damaged the AP, and might damage the next one. Just check the voltage across the pairs while something POE-aware is plugged into it. You should get about 48V DC.
