Adding or Replacing Modules

If a module has to be replaced with one of the same type, or you are expanding
the switch capability by adding a module in a slot where one was not previ-
ously installed (since the last switch reboot), the replaced or new module is
immediately operational; there is no interruption to the switch operation.
When you are replacing a module in a slot with another module of different
type, the new module does not immediately operate, since the switch contains
configuration (such as VLAN membership) involving ports of the older
module. Replacing the module does NOT automatically remove such config-
uration. To remove the older configuration, run the following command from
the command line interface:
no module X
where, X is the slot letter of the module to be replaced. After you run
command, the slot is restored to a state where no module was previously
installed. When you insert the new module, the module operates immediately.
