Online Insertion and Removal
Cisco ASR 9001 Router modular port adapters (MPAs) support online insertion and removal (OIR).
Modular port adapters (MPAs) support three types of OIR:
•Soft OIR
Soft OIR uses the IOS XR hw-module subslot 0/0/1 reload, hw-module subslot 0/0/1 shutdown,
and no hw-module subslot 0/0/1 shutdown commands to complete online insertion and removal.
Refer to the Hardware Redundancy and Node Administration Commands on the Cisco ASR 9000
Series Router chapter of the Cisco ASR 9000 Series Aggregation Services Router System
Management Command Reference online for command syntax.
•Managed OIR
A managed online insertion and removal of Modular port adapters (MPAs) is comprised of these
steps:
1. Shut down the MPA with the hw-module subslot 0/0/1 shutdown command.
2. Confirm that the LEDs have gone from green to off.
3. Execute the do show plat command to verify that the MPA to be removed is in the disabled
state.
4. Physically remove the MPA to be replaced.
5. Physically insert the replacement MPA
6. Return the MPA to the up state with the no hw-module subslot 0/0/1 shutdown command.
•Hard OIR
Hard OIR is the physical online insertion and removal of Modular port adapters (MPAs) without
software commands. Four types of hard OIR are supported:
