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

Router#
