Troubleshooting

When attempting to identify the cause of the trouble, it is helpful to begin with the two most
basic areas which cause malfunctions:
• The flow of electric current from the power supplies to the cards.
• The flow of data between the program software, the circuit cards, and the attached
audio devices.

Troubleshooting power supply problems

Electric current in the matrix starts at the power supplies, travels through the matrix's
backplane connectors, and then travels to the circuit cards themselves. When power-supply
problems occur, those three areas—the power supplies, the backplane connectors, and the
circuit cards—should be explored to identify where the trouble is occurring. Solving power-
supply problems starts with identifying the specific component causing the problem.
The matrix's backplane connectors are part of the matrix's infrastructure and are not
serviceable by field personnel. If it is determined that a problem is in the matrix's backplane
connectors, the matrix must be returned for repair. Backplane connector malfunctions are
rare, but should be considered as possibilities.
Note: Clear-Com may ship a spare matrix to use while the damaged matrix is being repaired
depending on the support status. For more information, see your warranty and support
documentation.
11.3.1.1
A lit power-supply light on a component indicates that the matrix's electric current has
traveled successfully to that component and is powering the component. For example, if the
power-supply lights on the CPU card are lit, the electric current has successfully traveled
from the matrix's power supplies to the CPU card.
If a power-supply light is not lit on a component, the electric current has not reached that
component for some reason. Knowing where the current has stalled helps to identify the
component that needs repair.
For example, if all of the power-supply lights on all cards do not light, the electricity supply
may have given out either in the power supplies themselves or in the matrix's backplane
connectors. A faulty connector on the backplane, or a crack in the backplane can cause all
of the matrix's power-supply lights to go out because the path on which the electric current is
traveling has been blocked.
This is a rare problem, but one to consider as a possibility. Repairing the problem in this
case would involve determining whether the problem is in the power supplies or the
backplane connectors.
When a problem is identified in the power supplies or the circuit cards, the suspect
component can be replaced with a properly functioning component to see if the problem is
repaired.
