A stack member that is disconnected from the stack maintains this configuration. To remove a stack member from the stack, disconnect the stacking cables from the unit. You may disconnect the cable at any time, whether the unit is powered or unpowered, online or offline. Examples of Removing a PE Stack Member The following example shows the status of stack-unit 1 before it is removed from the PE stack.
