Installing and replacing a module 77
—To remove a module from an active system, you must disable the module before you remove it. Disabling the slot before removing the module provides a clean disconnect from all services.
The following procedure includes directions for disabling the module.
—If you remove an 8672ATME, 8672ATMM, or 8683POSM module from an operating switch without turning off the chassis power and the module you insert has the same type MDAs installed as the module that you removed, the system saves the configuration.
—If you remove an 8672ATME, 8672ATMM, or 8683POSM module from an operating switch without turning off the chassis power and the module you insert has different MDAs installed than the module that you removed, you must reconfigure the module. Nortel recommends that you save the original configuration in a file for future use.
—If you replace a module with a different type module, the system discards the configuration of the old ports and adds the new ports to either the default VLAN or a null VLAN, depending on the operating mode of the switch.
—If 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.
—If you replace an 8691omSF or 8692omSF module, all the other modules in the chassis reset and revert to their saved configuration settings. If you did not save the configuration settings for a module, the module reverts to its factory default settings.
