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
Note 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.
Modular Port Adapter (MPA) Installation and Removal
This section provides step-by-step instructions for removing and installing a modular port adapter
(MPA).
Caution 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.
To remove and install a modular port adapter (MPA), perform these steps:
Step1 To insert the MPA, carefully slide the MPA all the way until it stops.
Note The modular port adapter (MPA) will slide easily into the slot if it is properly aligned on the tracks. If
MPA does not slide easily, do NOT force it. Remove the MPA and reposition it, paying close attention
to engaging it on the tracks.
Step2 To fully seat the MPA, use a number 2 Phillips screwdriver to tighten the jackscrew on the MPA.
Note Avoid over torquing the modular port adapter (MPA) jackscrew when installing the MPA.
Tighten the jackscrew on the MPA to a torque of 17 +/-1 inch-pound. Do not use a power
screwdriver to tighten the MPA jackscrew.
Step3 To remove the MPA, use a number 2 Phillips screwdriver to loosen the lock screw on the MPA. Make
sure that the cables are disconnected from the MPA first.
Step4 Grasp the MPA and pull the MPA from the slot.
