If you remove an interface module from an operating switch without
turning off the chassis power and replace it with the same type module,
the system restores the configuration.
If you remove a 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 which was
removed, the system saves the configuration.
If you remove a 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 which was
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 the new ports are added
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, add adds new ports to either the default VLAN or an
unassigned VLAN, depending on the operating mode of the switch.
If you replace a 8691SF or 8692SF 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.
Action
Disconnect any cables attached to the ports on the module.
CAUTION
Do not operate the Ethernet Routing Switch 8600 with an
empty module slot. If you need to replace a failed module
and you do not yet have a replacement module, leave the
failed module installed or install a filler panel.
Using a Phillips screwdriver, loosen the 2 captive screws that secure
the module to the chassis
