OIR Procedures
The following procedures describe using the OIR process to remove and replace data and voice modules.
Removing a Module
From a console terminal issue the hw-module subslot <subslot> stop command. The service module
adapter LED blinks, then 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]

Inserting a Data or Voice Module
This step is only required if the oir-stop command was issued and the module was not physically
removed from the slot. If the module was physically removed, this command is not needed.
From a console terminal issue the hw-module sm {slot} oir-start command. The console displays a
output showing the module changing states. See the following output:
Router# hw-module sm 2 oir-start

Hot-Swapping Procedures
The following items can be hot-swapped:
• Fan trays
• Power supplies only when the router is backed up with an RPS
See the “Replacing a Fan Tray” section on page 6-34 and the “Replacing Power Supplies and Redundant
Power Supplies” section on page 6-31.
