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.
