Replacing the Stack Member with a New Unit

1. Follow the process in Removing a Unit from the Stack to remove the desired stack member.
2. Follow the process in 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.
• It is not necessary to preconfigure the unit.

If a stack member is replaced with a unit of a different model number, follow these steps:

3. Follow the process in Removing a Unit from the Stack to remove the desired stack member.
4. Remove the now-absent stack member from the configuration by issuing the no member command in Config Stack mode.
5. Add the new stack unit to the stack using the process described in 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 ensure that the stack does not get divided into two separate stacks, causing the election of a new manager.
