8.0 Troubleshooting 

Below is a listing of several problems that may arise during the installation & operation of 
the modules. If you are having difficulty installing or operating the modules please refer 
to this list below. 
 

Problem: 

Module does not fit in chassis slots 

Action: 

Check module orientation. Meridian “Globe” must be oriented on the top left 
hand side of the module. Make sure the card guides in the chassis are aligned 
with the extrusion on the module.  

 
Problem: 

Card power LED does not light when power to the module/subrack is   

                    applied or power indicator turns on and off 

Action: 

Check power supply to ensure that it is plugged in and turned on. If flashing 
continues, move module to another chassis or location in the same chassis, if 
available. 

 
Problem: 

No video at output of module 

Action: 

Check the SpectraView display on the monitor for an indication of what the 
problem may be. Also, check to ensure that the video channel-specific LEDs are 
on (Green). Also, check to ensure that the optical  LEDs are ON. If no video is
