After the new unit loads, it synchronizes its running and startup configurations with the stack.
Manually Assigning a New Unit to an Existing Stack
To manually assign a new unit a position in an existing stack, use the following steps.
1. On the stack, determine the next available stack-unit number, and the management priority of the management unit.
EXEC Privilege mode
show system brief or show system stack-unit
2. On the new unit, number it the next available stack-unit number.
EXEC Privilege mode
stack-unit stack-unit-number renumber stack-unit-new-number
3. (OPTIONAL) On the new unit, assign a management priority based on whether you want the new unit to be the stack manager.
CONFIGURATION mode
stack-unit stack-unit-number priority priority-number
4. Assign a stack group to each unit.
CONFIGURATION mode
stack-unitstack-unit-number stack-group stack-group-number
5. Connect the new unit to the stack using stacking cables.
The following example shows adding a stack unit with a conflicting stack number (before).

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.
