OIR Procedures Appendix A Online Insertion Removal and Hot-Swapping 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.
