Dell Networking OS Behavior: A stacking conguration is handled as follows:
• If a stack unit goes down and is removed from the stack, the logical provisioning congured 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 conguration 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 dierent stack
groups congured. In this case, the stack-group conguration 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.
1. Convert a 4x10GbE port to 40GbE mode.
CONFIGURATION mode
no stack-unit unit-number port port-number portmode quad
stack-unit number is the ID number of the stack unit. The valid values are from 0 to 11.
2. Save the port conguration.
EXEC Privilege mode
write memory
3. Reload the stack for the port reconguration to take eect.
EXEC Privilege mode

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 conguration and if necessary, re-attach the cables to ports in a dierent stack group that
has been enabled for stacking. Then reload the stack for the change to take eect.
1. Remove a stacking port from a stack.
CONFIGURATION mode

2. Save the port conguration.
