Hi Guys,
One of my switch unit suddenly lose the PoE capability. Switch type is WS-C3850-24XU. Below is the output when I do some checking.
FaultySwitch#show platform software ilpower system 2
ILP System Configuration
Slot: 2
ILP Supported: Yes
Total Power: 0
Used Power: 0

Power Used: 0
Power Threshold: 0
Operation Status: Off
Pool: 2

Here is the comparison on the normal switch.

Is it possible the PoE feature just turned off for some reason? Thanks.

Hi Marce,
Yes, here is the log I found on the switch.
%PLATFORM_STACKPOWER-4-BISP_PORT_A_SC: Switch 2 experienced a short-circuit BISP event on port 1

Whether the bug report matches or not , consider using the latest advisory software release for the 3850 and check if that can help

Hello,
are both the working and the non-working unit running the same IOS-XE version ?
Release Gibraltar-16.12.5b MD is the recommended release...

Hi Georg,
Yes, both switch are the same type and running the same OS, 16.3.7. Even they are on the same stack.
