Starting the system after a module replacement

After you a replace a module on the chassis, you can expect the following results:

•In a running system, when you replace an I/O module with a module of the same type, the system restores the configuration of all the ports.

•When you replace a module with one of a different type, the system discards the configuration of the old ports, and the new ports are added to either the default VLAN or a null VLAN, depending on the operating mode of the switch.

•When you save the configuration in nonvolatile random access memory (NVRAM), turn off the switch, replace a module with a different module type, and turn the system on again, the system discards the configuration of the old ports, and adds new ports to either the default VLAN or an unassigned VLAN, depending on the operating mode of the switch.

Starting the system with an empty slot

When you save the configuration in NVRAM, shut down the system, remove a module, turn on the chassis with that slot empty, and then populate the slot with a module of the same type as the one previously there, the system is not able to restore the original configuration.
