Hello
I am getting the following messages.
Does this mean the cable needs to be replaced?
The problem appears to be on the 2nd switch in the stack. Can someone advise on the procedure
to fix this issue and will there be an outage of any kind during the replacement?
#sh switch stack-ports
Switch # Port 1 Port 2

Hey,
It could be either port or cable. Try replacing the stack cable with a good known one.
HTH.

Can a stacking cable on the 2nd switch of 4 being removed "hot swappable"?
What adverse reactions could occur?

Sometimes you have to take a screwdriver to the stackcables to tighten them correctly, just don't heave on them and strip the screws. snug only... If it still happens replace cable and try again.
