Split an S-Series Stack To split a stack, unplug the desired stacking cables.You may do this at any time, whether the stack is powered or unpowered, and the units are online or ofline. Each portion of the split stack retains the startup and running configuration of the original stack. For a parent stack that is split into two child stacks, A and B, each with multiple units: • If one of the new stacks receives the master and the standby management units, it is unaffected by the split. • If one of the new stacks receives only the master unit, that unit remains the stack manager, and FTOS elects a new standby management unit. • If one of the new stacks receives only the standby unit, it becomes the master unit of the new stack, and FTOS elects a new standby unit. • If one of the new stacks receives neither the master nor the standby management unit, the stack is reset so that a new election can take place.
