Module removal and switch behavior considerations
After you remove or replace a module in your chassis, you can expect the following results.
• If you replace a module with a different type of module, 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.
• If you remove an interface module from an operating switch, and replace it with the same
type of module, the system restores the configuration. If you save the configuration in
nonvolatile random access memory (NVRAM), turn off the switch, replace a module with
a different type of module, and turn the system on again, the system discards the
configuration of the old ports and add adds new ports to either the default VLAN or an
unassigned VLAN, depending on the operating mode of the switch.
• The ability of the switch to load configuration files for modules depends on whether the
module is present in the chassis. By design, configuration files do not completely load if
the module is not installed.
• If you booted the switch without the modules and want to completely load the configuration
files, there are two methods you can use. You can install the module and then reboot the
switch. Or, you can install the module, and source and save the configuration file (which
avoids a reboot).
SF/CPU modules
If you replace a 8393 SF/CPU or 8394 SF/CPU module, all the other modules in the chassis
reset and revert to their saved configuration settings. If configuration settings for a module
were not saved, the module reverts to its factory default settings.
