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

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.
