Adding a Configured Unit to an Existing Stack
To add a configured unit to an existing stack, use the following commands.
If a stack unit goes down and is removed from the stack, the logical provisioning configured 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 configuration conflict occurs between
the new unit and the provisioned stack unit, the configuration of the new unit takes precedence.
1. Add the configured 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 configuration mode.

5. Configure the ports on the added switch for stacking.
CONFIGURATION mode
stack-unit 0 stack-group group-number
stack-unit 0: defines the default ID unit-number in the initial configuration of a switch.
stack-group group-number: configures a port for stacking.
6. Save the stacking configuration on the ports.
