When the stack-group configuration is complete, the system prints a syslog for reload.
Dell#configure
Dell(conf)#stack-unit 4 stack-group 13
Dell(conf)#02:39:12: %STKUNIT4-M:CP %IFMGR-6-STACK_PORTS_ADDED: Ports Fo 4/52 have
been configured as
stacking ports. Please save and reload for config to take effect

Dell#02:39:18: %STKUNIT4-M:CP %SYS-5-CONFIG_I: Configured from console
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.
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 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.
