Is it possible to uppgrade IOS image on a 3750E stack and not restart the entire stack at the same time. What I want is to restart one member at the time and have full functionality at the other members. I got this message "Systems with incompatible software
have been added to the stack" and the switch will not enjoy the stack and do not do any traffic forwarding at the ethernet ports. And I can't administrate the switch by console port.
