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.
Example of Adding a Stack Unit with a Conicting Stack Number (Before and After)

The following example shows adding a stack unit with a conicting stack number (after).
Adding a Congured Unit to an Existing Stack
To add a congured unit to an existing stack, use the following commands.
If a stack unit goes down and is removed from the stack, the logical provisioning congured 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 conguration conict occurs between the new unit and
the provisioned stack unit, the conguration of the new unit takes precedence.
1 Add the congured 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 conguration mode.

5 Congure the ports on the added switch for stacking.
CONFIGURATION mode
• : denes the default ID unit-number in the initial conguration of a switch.
• stack-group group-number: congures a port for stacking.
6 Save the stacking conguration on the ports.
