Add Units to an Existing Stack

You can add units to an existing stack in one of three ways.
• By manually assigning a new unconfigured unit a position in an existing stack.
• By adding a configured unit to an existing stack.
• By merging two stacks.
If you are adding units to an existing stack, you can either:
• allow Dell Networking OS to automatically assign the new unit a position in the stack, or
• manually determine each units position in the stack by configuring each unit to correspond with the stack before connecting it.
• If you add a unit that has a stack number that conflicts with the stack, the stack assigns the first available stack number.
• If the stack has a provision for the stack-number that will be assigned to the new unit, the provision must match the unit type, or
Dell Networking OS generates a type mismatch error.
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.
