Its a power controller failure. The post says:
POST: Inline Power Controller Tests : Begin
POST: Found inline power controller write failure, inst 0
POST: Inline Power Controller Tests : End, Status Failed
POST: Inline Power feature is disabled on this switch
This happened on a remote site after a thunderstorm.

Subject: Re: 3750 and power inlnie
Hi Geert,
I had a similar issue on 3560 PoE switches where the 25th phone does not get the power.
This is due to the fact that the power available on the switch was 370 W and by default, each port is allocated 15.4 W.
(370 / 15.4 = 24.026 phones max).
As per one of the Voice Experts in the GS, I tweaked the power on the switch ports to 6.3W ( IP Phone 7941) and 5.0 W ( IP Phone 7911) and so on. By this way, I managed to utilise more or less all the ports.
( IP Phone 7971 should also work with 6.3 W which I do not remember exactly).
To do this, go to the interface config mode and run : power inline consumption 6300
You may get a warning, but that is ok to ignore. Better shutdown the port before apply this command.
I know what I have written above may not be fully relevant to your case, but may be handy for later usage.
Try shutting down the ports and enable / Or reload the 4th switch during non-production hours.
Let us know as to how you fix this.
Regards,
Ananth

Hi group,
Is it possible for a 3750 to fail completely regarding PoE, but keep functioning normally for the rest ?
Are all PoE-functions controlled by one critical "power controller" maybe ?
I have a PoE-capable switch, where suddenly the available power has dropped to 0 and not a single port gets powered....
sh power inline
