Modular Port Adapter Installation and Removal
This section provides step-by-step instructions for removing and installing a modular port adapter
(MPA) in a modular line cards (MLC).
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly
touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94
To remove and install a MPA in a MLC, do the following:
To insert the MPA in the MLC, locate the guide rails inside the MLC that hold the MPA in place. They
Step 1

Step 2
connector. When fully seated, the MPA might be slightly behind the MLC faceplate.
Note

Step 4
MPA.
Grasp the MPA and pull the MPA from the MLC. (You have already disconnected the cables from the
Step 5
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.
Cleaning Optical Devices
See the
cleaning optical devices.
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.
Avoid over torquing the MPA jackscrew when installing the MPA. Tighten the jackscrew on the
MPA to a torque of 17 +/-1 inch-pound.
