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 a Stack
• Removing Front End Port Stacking
Removing a Unit from a 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.
The following example shows removing a stack member (before).

NOTE:
Each unit in the stack has a stack number that is either assigned by you or Dell EMC Networking OS. To manually
renumber stack members, use the stack-unit old-unit-number renumber new-unit-number command.
Renumbering stack members causes the entire stack to reload.
