Cisco ASR 9901 Hardware Installation Guide

• 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:
If the bay is empty when the Cisco ASR 9001 router modular line card (MLC) boots you can do the
following:
• Insert a 20 GE MPA
• Remove and then insert a replacement 20 GE MPA
If the MLC boots with a 20 GE MPA in the bay you can remove and then insert a replacement 20 GE
MPA
If the MLC boots with a 4 10-GE MPA in the bay you can remove and then insert a replacement 4 10-GE
MPA
If the MLC boots with a 2 10-GE MPA in the bay you can remove and then insert a replacement 2 10-GE
MPA
Only replacement with same types of MPA is supported by Managed OIR and
Hard OIR. An empty bay during the Cisco ASR 9001 Router modular line card
(MLC) bootup defaults to 20 GE MPA mode.
Note
Modular Port Adapter (MPA) Installation and Removal
This section provides step-by-step instructions for removing and installing a modular port adapter (MPA).
When performing these procedures, wear a grounding wrist strap to avoid ESD damage to the modular port
adapter (MPA). Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch
the midplane or backplane with your hand or any metal tool, or you could shock yourself.
