Soft OIR uses the IOS XR hw-module subslot rack/slot/subslot reload, hw-module subslot

rack/slot/subslot shutdown, and no hw-module subslot rack/slot/subslot shutdown commands to

complete online insertion and removal.

A managed online insertion and removal of Modular port adapters (MPAs) is comprised of the following

steps:

• Shut down the MPA with the hw-module subslot rack/slot/subslot shutdown command.

• Confirm that the LEDs have gone from green to off.

• Execute the do show platform command to verify that the MPA to be removed is in the disabled

state.

• Physically remove the MPA to be replaced.

• Physically insert the replacement MPA

• Return the MPA to the up state with the no hw-module subslot rack/slot/subslot shutdown

command.

You can perform the OIR in a running system, by not executing any commands:
