Modular port adapters (MPAs) support the following types of OIR:
• Soft OIR
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.
• Managed OIR
A managed online insertion and removal of Modular port adapters (MPAs) is comprised of the following

• Shut down the MPA with the hw-module subslot rack/slot/subslot shutdown command.
• Confirm that the LEDs have gone from green to off.

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.
