Online Insertion and Removal
The online insertion and removal (OIR) feature allows you to remove and replace modules while the system
is online. You can shut down the modules before removal and restart them after insertion, without causing
other software or interfaces to shut down.
Do not remove or install more than one module at a time. After you remove or install a module, check the
module LEDs before continuing.
Note
When a module is removed or installed, the switch stops processing traffic for the module and scans the system
for a configuration change. Each interface type is verified against the system configuration, and then the
system runs diagnostics on the new module. There is no disruption of normal operation during module insertion
or removal.
The switch can bring up only an identical replacement module online. To support the OIR of an identical
module, the module configuration is not removed from the running-config file when you remove a module.
If the replacement module is different from the removed module, you must configure it before the switch can
bring it online.
Layer 2 MAC addresses are stored in an EEPROM, which allows modules to be replaced online without
requiring the system to update switching tables and data structures. Regardless of the types of modules installed,
the Layer 2 MAC addresses do not change unless you replace the supervisor engine. If you do replace the
