Installing and Removing Line Cards and Transceiver Modules
To remove and install a MPA, do the following:
1. To insert the MPA, locate the guide rails inside the MLC that hold the MPA in place. They are at the top
left and top right of the MPA slot and are recessed about an inch.
2. Carefully slide the MPA all the way in the MLC until the MPA is firmly seated in the MPA interface
connector. When fully seated, the MPA might be slightly behind the faceplate.
Note
The MPA will slide easily into the slot if it is properly aligned on the tracks. If the MPA does not slide easily,
do NOT force it. Remove the MPA and reposition it, paying close attention to engaging it on the tracks. Push
the MPA inside the slot until you hear a click. Continue to push the MPA further until you hear a second click.
The MPA is fully seated only after the second click is heard.
3. After the MPA is properly seated, use a number 2 Phillips screwdriver to tighten the captive screws on
the MPA. Ensure that you first tighten the right screw and then the left.
Note
Avoid over torquing the MPA captive screws when installing the MPA. Tighten the captive screws on the
MPA to a torque of 17 +/-1 inch-pound.
4. To remove the MPA from the MLC, use a number 2 Phillips screwdriver to loosen the captive screws on
the MPA. Ensure that you first loosen the right screw and then the left.
5. Grasp the MPA and pull the MPA from the MLC. (You have already disconnected the cables from the
MPA.)

Optical Device Installation and Removal

Any contamination of the fiber connection can cause failure of the component or failure of the whole system.
A particle that partially or completely blocks the core generates strong back reflections, which can cause
instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take before making
fiber-optic connections.

Safe Removal of CFP2-DCO Modules

The CFP2-DCO modules, when in use, can exhibit high temperatures. Therefore, we recommend you to be
careful in handling these optical modules while removing them from ports of MPAs.
Use the following steps to remove CFP2-DCO modules from a router safely:
1. Use the interface
module, and then wait for 60 seconds.
