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.
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.

• stack-unit 0: 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.
EXEC Privilege mode

7. Reload the switch.
EXEC Privilege mode

Dell Networking OS automatically assigns a number to the new unit and adds it as member switch in the stack. The new unit
synchronizes its running and startup congurations with the stack.
