Installing and Removing Modular Port Adapters
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

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:
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 modular port adapter card (MPA) is active, the STATUS LED will illuminate green.
Step 2 When the MPA STATUS LEDs are green, all associated interfaces are configurable.
•If a MPA is replaced with a module of the same type (as in an OIR or hardware swap), the previous configuration is reinstated when the MPA becomes active.
•If a MPA was not previously installed in the same slot or subslot, then the configuration for all associated interfaces is empty.
Note New interfaces are not made available until you configure them.
