Hello community,

a customer has some issues with a stack consisting of two X465-48T Switches where we received false notifications about power supply failures. The stack is running on 31.7.1-Patch1-17, I checked the latest patches and they have no such bugs in their resolved issues list:

Additionally, the output of show power detail is suspicious considering the stack is running fine.

1. The switch only has 2 slots but the output suggests that there are many more.

2. The PSU that are recognized are shown as "powered off" (The switch LEDs also suggest that)

A reseat of the redundant PSUs changed nothing.

Taken from Netsight:
- Summit Series ONIE Stack (2 modules)
- Slot 1 X465-48T
- Slot 2 X465-48T

Can this be considered an unfixed bug? We will likely do a restart so we can monitor PSUs properly again but we still have to schedule it.
