Diagnostics
When it comes to troubleshooting your COM2000 system, the COM46 card has a few built-in
mechanisms that can assist you. Each of these can be very helpful in diagnosing general issues
associated with system status and card connections that will be covered in the following sections.
13.1
Indicator Lights
The nine indicator lights the COM46 & COM46-FLX faceplate have multiple functionalities. In
addition to providing a manual toggling ability of the Tuner 9 LED by utilizing the LED
controls on the Tune page the lights also exhibit a set of predefined behaviors for several
conditions.
In recognizing the behaviors associated with the three indicator lights, you must first familiarize
yourself with the three possible LED states. Figure 68 below names and describes them, and
provides a color by which the states will be defined in the following sections.

Power Supply Issues
Unless a COM46 card has intentionally been removed from the COM360 chassis, the “PWR”
light on every card in the system should be lit. If none of the COM46 LEDs on a chassis are lit,
the power supply has likely been disrupted.
Check for the following:
The AC cords on each module are completely attached and plugged in.
Both modules are locked in place.
The power supply fans are running.
On
The LED emits a steady green light.
Off
The LED is not lit at all.
Flash
The LED exhibits an on-off pattern once a second.
