Reload each unit in the stack. After the reload is complete, the four units come up as a stack with unit 1 as the management unit, unit 2 as
the standby unit, and the remaining units as stack-members. All units in the stack can be accessed from the management unit.
NOTE: Before executing show commands, you must wait for 10 to 15 seconds for the download-agent process to start.
To view the stack unit information after the reload, use the show system brief command.
Add Units to an Existing Stack
You can add units to an existing stack in one of three ways.
• By manually assigning a new uncongured unit a position in an existing stack.
• By adding a congured 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 conguring each unit to correspond with the stack before connecting it.
• If you add a unit that has a stack number that conicts with the stack, the stack assigns the rst 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 congurations 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.
