Hello,
We have a stack of 4 1960 switches. One of them (ID 1 - conductor) had problems with POE ports. We got a new one to replace. When we disconnected the power supply from the "damaged" stack, it got an error and it looked like it would reset.... No network availability on the other switches for about 7 minutes :(.
From the information from support it would seem that this is normal...
There was a log like this in the stack:
%SYSLOG-F-OSFATAL: caught segmentation fault exception at address 0xe4cc
