At this point, if Unit 2 is powered off or rebooted due to an unexpected
failure, show switch gives the following output:
console#show switch
SW Management
Status
--- ---------
1 Stack Member
2 Unassigned
3 Mgmt Switch
4 Stack Member
When the failed unit resumes normal operation, the previous configuration
that exists for that unit is reapplied by the stack master.
To permanently remove the unit from the stack, enter into Stack Config
Mode and use the member command, as the following example shows.
console#configure
console(config)#stack
console(config-stack)#no member 2
console(config-stack)#exit
console(config)#exit
console#show switch
