Managing Switch Stacks

12-13

•

Follow the process in section Removing a Unit from the Stack to remove the desired stack 
member.

•

Follow the process in section Adding a Unit to an Operating Stack to add a new member to the 
stack with the following exceptions:

–

Insert the new member in the same position in the stack as the one removed.

–

Preconfiguration described in step Preconfigure the new unit, if desired. of that procedure 
is not required.

Second, if you replace a stack member with another unit of a different model number, use the 
following process:

•

Follow the process in section Removing a Unit from the Stack to remove the desired stack 
member.

•

Remove the now-absent stack member from the configuration by issuing the command no 
member command.

•

Add the new stack unit to the stack using the process described in section Adding a Unit to an 
Operating Stack. The unit can be inserted into the same position as the unit just removed, or 
the unit can be inserted at the bottom of the stack. In either case, make sure all stack cables are 
connected with the exception of the cable at the position where the new unit is to be inserted to 
insure that the stack does not get divided into two separate stacks, causing the election of a 
new master.

1.

If particular numbering is required, it is recommended that stack members be assigned specific 
numbers when they are first installed and configured in the stack, if possible.

2.

If the desired stack unit number for a particular unit is unused, a unit can be renumbered 
simply by using the switch <oldunit-id> renumber <newunit-id> CLI command. This 
command is found in global config mode.

3.

If the newunit-id has been preconfigured, you may need to remove the newunit-id from the 
configuration before renumbering the unit.

4.

If reassignment of multiple existing stack unit numbers is necessary, there are a number of 
implications in terms of mismatching of configuration. In this case, it is recommended that all 
units except the master be powered down and added back one at a time using the procedure in 
Section Adding a Unit to an Operating Stack.
