What issues if any, will we run into when adding a switch currently connected via cat6 to a stack? The stack has Layer 3 routing enabled but the other one located in a different area of the suite does not have Layer 3 enabled. We will have a maintenance window to move it and add it to the stack. Actually we are rearranging everything so all 4 switches will be offline and brought back up at the same time in a stack configuration.
