Optical Device Installation and Removal
Procedure
Step 1
To insert the MPA, carefully slide the MPA all the way until it stops.
Note
Step 2
To fully seat the MPA, use a number 2 Phillips screwdriver to tighten the jackscrew on the MPA.
Note
Step 3
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.
Step 4
Grasp the MPA and pull the MPA from the slot.
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.

Checking the Installation
This section describes the procedures you can use to verify the modular port adapter (MPA) installation, and
includes information on these topics:
Verifying the Installation
This section describes how to verify the modular port adapter (MPA) installation by observing the MPA LED
states.
When the system has reinitialized all interfaces, the MPA STATUS LEDs should be on (green). The port
LEDs (C/A and A/L) may be on (green), depending on your connections and configuration.
To verify that a MPA is installed correctly:
Procedure
Step 1
Observe the console display messages and verify that the system discovers the modular line card (MLC),
while the system reinitializes each interface, thus:
• As the MPA is initialized, the STATUS LED will first be amber, indicating that power is on. When the

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.
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.
