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.
