PoE Overload/Fault with AP3715i

Hi.  I was wondering if anyone is seeing the same issue I am.  I have over 1200 APs installed on a couple of C5210 controllers running 09.21.01.0179 code.  Those 1200+ APs are broken down to the following three models:

650+ are 3715i
390+ are 3825i
150+ are 3610i

These are connected to either C3G124-48P (running 06.61.09.0012) or C5G124-48P2 (running 06.81.01.0027 code) switches.

It seems like every week or so I get a 3715i AP that is down and when I look at the switch port, it says "PoE Overload or Fault".  When I replace the AP with another new 3715i, the switch port is fine and the new AP comes up instantly so it doesn't appear to be a switch issue.   I've tried connecting the problem AP to different PoE switches in our lab as well as just plugging it in to a PoE Injector and it won't come up.  It's dead, so we get it RMA'd and a day later a new one shows up.  I wouldn't care if this happening once in a while, but I've had to replace 20+ access points and it only seems to happen to the 3715i.  We've opened a case with the GTAC a few months ago, but never heard back.  I'm getting tired of replacing APs.  I was just curious if anyone was having the same problem.

Regards,

Hello Rich, 

Sorry you have had issues with the 3715. If you can provide the ticket number I will look into it for you. We can have a failure analysis run for you on your most recent RMA.

Hi Doug.  We just RMA'd (3) 3715s with this issue today (case # 01167363).  I should have the replacements in a couple of days and these should be on their way back to you guys by the end of the week.

Hello Rich
I have opened a new case # 01167380 to track these failures and to inquire with our Quality Group to see if we are noticing any POE failure trends.
