Optical Device Installation And Removal; Checking The Installation - Cisco ASR 9000 Series Installation Manual

Installing and Removing Modular Port Adapters
Note
To remove the modular port adapter (MPA) from the modular line card (MLC), use a number 2 Phillips
Step 4
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) from the modular line
card (MLC). (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.

Checking the Installation

This section describes the procedures you can use to verify the modular line card (MLC) and modular
port adapter (MPA) installation, and includes information on the following topics:

Verifying the Installation
This section describes how to verify the modular line card (MLC) and modular port adapter (MPA)
installation by observing the modular line card (MLC) LED states, the modular port adapter (MPA) LED
states, and the information displayed on the console terminal.
When the system has reinitialized all interfaces, the modular line card (MLC) STATUS LED should be
green (on) and the modular port adapter (MPA) STATUS LEDs should be green (on). The port LEDs
(C/A and A/L) may be green (on), depending on your connections and configuration. The console screen
also displays a message as the system discovers each interface during its reinitialization.

Avoid over torquing the modular port adapter (MPA) jackscrew when installing the modular port
adapter (MPA). Tighten the jackscrew on the modular port adapter (MPA) to a torque of 17 +/-1
inch-pound.
