OIR Procedures
The following procedures describe using the OIR process to remove and replace data and voice modules.
Remove a Module
Note Ensure that the module is available before you issue the command to remove it.
From a console terminal run the hw-module subslot <subslot> stop command. The service module
adapter LED blinks, turns off, and the console displays a prompt signaling the module can be removed.
See the following output:
Router# hw-module subslot 2/0 stop
Proceed with stop of module? [confirm]

Insert a Module
You require to run this step only if you run the oir-stop command when the module is not physically
removed from the slot. If the module is physically removed, you do not require to run this command.
From a console terminal issue the hw-module sm {slot} oir-start command. The console displays output
that shows the module change states:
Router# hw-module sm 2 oir-start
