Remove Units or Front End Ports from a Stack
To remove units or front end ports from a stack, use the following instructions.
• Removing a Unit from an S-Series Stack
• Removing Front End Port Stacking
Removing 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: If you remove a unit in the middle of the daisy chain stack, the stack is split into multiple parts and each
forms a new stack according to the stacking algorithm described throughout this chapter.
