Installing and Removing Modular Port Adapters
Online Insertion and Removal
Cisco ASR 9000 Series Router modular line cards (MLCs) and modular port adapters (MPAs) support
online insertion and removal (OIR). Modular port adapters (MPAs) can be inserted or removed
independently from the MLC. OIR of a MLC with installed modular port adapters (MPAs) is also
supported.
Modular port adapters (MPAs) support the following three 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. 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 the
following steps:
Shut down the MPA with the hw-module subslot 0/0/1 shutdown command.
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.
Physically insert the replacement MPA
5.
Return the MPA to the up state with the no hw-module subslot 0/0/1 shutdown command.
6.
Hard OIR
Hard OIR is the physical online insertion and removal of Modular port adapters (MPAs) without
software commands. There are three types of hard OIR supported:
If the bay is empty when the Cisco ASR 9000 Series Router MLC boots, you can do the following:
Insert a 20GE MPA
–
Remove and then insert a replacement 20GE MPA
–
Insert a 4 10-GE MPA
–
Remove and then insert a replacement 4 10GE MPA
–
If the MLC boots with a 20GE MPA in the bay you can remove and then insert a replacement 20GE
MPA or a replacement 4 10GE MPA
If the MLC boots with a 4 10GE MPA in the bay you can remove and then insert a replacement 4
10GE MPA a or replacement 20GE MPA
Cisco recommends waiting for at least 2 minutes before doing successive MPA OIRs (Soft
Note
OIR or Hard OIR). An empty bay during the Cisco ASR 9000 Series Router MLC bootup
will default to 20GE MPA mode.
