Chapter 3 Installing Modules and Cables in the Chassis
Installing and Removing Modular Port Adapters
Note The modular port adapter (MPA) will slide easily into the slot if it is properly aligned on the
tracks. If the modular port adapter (MPA) does not slide easily, do NOT force it. Remove the
modular port adapter (MPA) and reposition it, paying close attention to engaging it on the tracks.
Step 3 After the modular port adapter (MPA) is properly seated, use a number 2 Philips screwdriver to tighten
the jackscrew on the modular port adapter (MPA).
Note Avoid over torquing the modular port adapter (MPA) jackscrew when installing the modular port
adapter (MPA).
Step 4 To remove the modular port adapter (MPA), use a number 2 Philips screwdriver to loosen the lock screw
on the modular port adapter (MPA).
Step 5 Grasp the modular port adapter (MPA) and pull the modular port adapter (MPA). (You have already
disconnected the cables from the modular port adapter (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
Refer to the Inspection and Cleaning Procedures for Fiber-Optic Connections document for information
on cleaning optical devices.
