12-14 Managing Switch Stacks
202-10088-01, March 2005
Moving a Master to a Different Unit in the Stack
1. Using the “movemanagement” command, move the master to the desired unit number. The
operation may take between 30 seconds and 3 minutes depending on the stack size and
configuration. The command is movemanagement <fromunit-id> <tounit-id>
2. Make sure that you can log in on the console attached to the new master. Use the show switch
command to verify that all units rejoined the stack.
3. It is recommended that the stack be reset with the reload command after moving the master.
Removing a Master Unit from an Operating Stack
1. First, move the designated master to a different unit in the stack using “Moving a Master to a
Different Unit in the Stack” on page 12-14.
2. Second, using “Removing a Unit from the Stack” on page 12-12, remove the unit from the
stack.
Merging Two Operational Stacks
1. It is strongly recommended that two functioning stacks (each having an independent master)
not be merged simply by the reconnection of stack cables. That process may result in a number
of unpredictable results and should be avoided.
2. Always power off all units in one stack before connecting into another stack.
3. Add the units as a group by unplugging one stacking cable in the operational stack and
physically connecting all unpowered units at that point.
4. Completely cable the stacking connections, making sure the redundant link is also in place.
5. Then, power up each unit, one at a time, by following “Adding a Unit to an Operating Stack”
on page 12-12.
