Adding a Congured Unit to an Existing Stack
To add a congured unit to an existing stack, use the following commands.
If a stack unit goes down and is removed from the stack, the logical provisioning congured for that stack-unit number is saved on the
master and standby units. When a new unit is added to the stack, if a stack group conguration conict occurs between the new unit and
the provisioned stack unit, the conguration of the new unit takes precedence.
1 Add the congured unit to the top or bottom of the stack.
2 Power on the switch.
3 Attach cables to connect ports on the added switch to one or more existing switches in the stack.
4 Log on to the CLI and enter global conguration mode.
