• stack-unit 1: 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.

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.
8. If a standalone switch already has stack groups congured.
Attach cables to connect the ports already congured as stack groups on the switch to one or more switches in the stack.
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.
Dell Networking OS Behavior: When you add a switch to a stack
• If you congure the new unit with a stack number that is already assigned to a stack member, the stack avoids a numbering
conict by assigning the new switch the rst available stack number.
• If the stack has been provisioned for the stack number that is assigned to the new unit, the pre-congured provisioning must
match the switch type. If there is a conict between the provisioned switch type and the new unit, a mismatch error message is
displayed.
Merge Two S-Series Stacks
You may merge two stacks while they are powered and online.
To merge two stacks, connect one stack to the other using user port cables from the front end user port.
• Dell Networking OS selects a master stack manager from the two existing managers based on the priority of the stack.
• Dell Networking OS resets all the units in the losing stack; they all become stack members.
• If there is no unit numbering conict, the stack members retain their previous unit numbers. Otherwise, the stack manager
assigns new unit numbers, based on the order that they come online.
• The stack manager overwrites the startup and running cong on the losing stack members with its own to synchronize the
conguration on the new stack members.
Split an S-Series Stack
To split a stack, unplug the desired stacking cables.
You may do this at any time, whether the stack is powered or unpowered, and the units are online or oine. Each portion of the split
stack retains the startup and running conguration of the original stack.
