Removing Units or Front End Ports from a Stack

Remove a Unit from an S-Series Stack
The running-configuration and startup-configuration are synchronized on all stack units. 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 do this at
any time, whether the unit is powered or unpowered, online or offline. Note that if you remove a unit in the
middle of the daisy chain stack, the stack will be split into multiple parts and each will form a new stack
according to the stacking algorithm described throughout this chapter.
