Remove (or power off) the stack master. One of the remaining stack members becomes the new stack master. All other members in the stack remain stack members and do not reboot. Preconfigure a Switch You can preconfigure (that is, supply a configuration to) a new switch before it joins the switch stack. You can specify the stack member number, the switch type, and the interfaces that are associated with a switch that is not currently part of the stack. Note: If you are replacing a switch with the same model in the same position in the stack, you do not need to preconfigure it. The new switch assumes the same configuration as the previous switch. To preconfigure a switch: 1. Issue the member unit-id switchindex command. 2. To view the supported unit types, use the show supported switchtype command. 3. Configure the unit that you defined in Step 1, just as if the unit were physically present. Ports for the preconfigured unit come up in a detached state. 4. To see the ports, use the show port all command. Now you can configure the detached ports for VLAN membership and any other port-specific configuration. After you preconfigure a unit type for a specific unit number, attaching a unit with a different unit type for this unit number causes the switch to report an error. In this situation, the output of the show switch command indicates a configuration mismatch for the new unit and the ports on that unit do not come up. To resolve this situation, you can change the unit number of the mismatched unit or delete the preconfigured unit type by issuing the no member unit-id command.
