I have 2 X440s in a stack at the moment, I am adding another x440 to the stack. If i break one of the stacking cables to connect to the 3rd switch, will the stack go down? I am trying to add this stack during production time and if the switches/stack goes down, its a major issue. We are trying to avoid any disruption of network traffic, so wondering if I can break the stack and still keep things active. I have 2 stacking cables between my two switches at the moment.
