Dell Networking OS Behavior: A stacking conguration is handled as follows:
• If a stack unit goes down and is removed from the stack, the logical provisioning congured for the stack-unit number is saved on the
master and standby switches.
• When you add a new unit to the stack and the stack already has an existing member unit with the same stack-unit number, the new
unit is assigned the smallest available unit number (from 0 to 11). A conguration mismatch between the newly added unit and a
logically provisioned unit occurs if the logical provisioning for the unit number and the added unit have dierent stack groups
congured. In this case, the stack-group conguration on the new unit takes precedence over the logical provisioning.
Converting Four 10 GbE Ports to 40 GbE Ports for
Stacking
Stacking is not supported on xed 40 GbE ports operating in 4x10G (quad) mode.

stack-unit number is the ID number of the stack unit. The valid values are from 0 to 11.

To display the stack-unit number, use the show system brief command.
Removing a Stack Group from Stacking Mode
To remove a stack group of four 10 GbE ports or one 40 GbE port from the stack, use the no form of the stack-unit unit-number
stack-group number command.
After entering the command, save the conguration and if necessary, re-attach the cables to ports in a dierent stack group that has been
enabled for stacking. Then reload the stack for the change to take eect.
