I inherited several Avaya ERS 3500 & 4800 switches and the 4800s are in a stack of three. I've updated all of the individual ERS switches no problem, but I don't see any specific instructions for updating a stack. I know the versions need to be the same across the stack, but not positive on how to accomplish that. Is it the same process as the individual switches, just carrying out by logging into the stack address and so the switches then update simultaneously?
