Adding a Configured Unit to an Existing Stack
To add a configured unit to an existing stack, use the following commands.
If a stack unit goes down and is removed from the stack, the logical provisioning configured 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
configuration conflict occurs between the new unit and the provisioned stack unit, the configuration of the
new unit takes precedence.
1 Add the configured 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 configuration 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 configurations with the stack.
