4. Configure a group of four 10 GbE ports or a single 40 GbE port for stacking.
CONFIGURATION mode
stack-unit 0 stack-group group-number
• stack-unit 0 defines the default ID unit-number in the initial configuration of a switch.
• stack-group group-number configures a group of 10 GbE ports or a single 40 GbE port for
stacking.
5. Save the stacking configuration.
EXEC Privilege mode

6. Reload the switch. Dell networking OS automatically assigns a number to the new unit and adds it as
member switch in the stack.
EXEC Privilege mode

The new unit synchronizes its running and startup configurations with the stack.
To add a standalone switch which has stack groups already configured to a stack, use the next steps.
7. Attach port cables to connect the ports in pre-configured stack groups to one or more switches in
the stack.
8. Power on the switch. 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.
Dell Networking OS Behavior: When you add a new switch to a stack:
• When you add a unit to a stack, the management unit performs a system check on the new unit to
ensure the hardware type (S5000) is compatible. The Dell Networking OS version performs a similar
check. If the stack is running 9.1(1.0) and a new unit is running a different software version, the new
unit is put into a card problem state. The new unit is then upgraded to use the same Dell Networking
OS version as the stack and is rebooted before joining the stack.
• If the new unit has been configured with a stack number that is already assigned to a stack member,
the stack avoids a numbering conflict by assigning the new switch the first available stack number.
• After the new unit loads, it synchronizes its running and startup configurations with the stack.
