OIR Procedures
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 sm {slot} oir-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 sm 4 oir-stop
*Nov 11 22:40:53.299: %ATMOC3POM-6-SFP_OUT: Interface ATM4/0 SFP has been removed.
*Nov 11 22:40:54.299: %LINEPROTO-5-UPDOWN: Line protocol on Interface ATM4/0, changed
state to down
SM Hardware slot 4 can be removed
Removing a Voice Module
Note All voice ports, controllers, transcoding, conferencing, and MTP dspfarm profiles should be shut down
before removing a voice module.
From a console terminal issue the hw-module sm {slot} oir-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 sm 4 oir-stop
*Nov 11 22:40:53.299: %ATMOC3POM-6-SFP_OUT: Interface ATM4/0 SFP has been removed.
*Nov 11 22:40:54.299: %LINEPROTO-5-UPDOWN: Line protocol on Interface ATM4/0, changed
state to down
SM Hardware slot 4 can be removed
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
Router#
*Nov 11 21:06:17.546: %ATMOC3POM-6-SFP_IN: Interface ATM2/0 OC3 MM SFP has been inserted.
Router#
*Nov 11 21:06:19.442: %LINK-3-UPDOWN: Interface ATM2/0, changed state to up
*Nov 11 21:06:20.442: %LINEPROTO-5-UPDOWN: Line protocol on Interface ATM2/0, changed
state to up
