• The flow of data between the program software, the circuit cards, and the
attached audio devices.
The following sections discuss troubleshooting these two basic categories of
problems.
TROUBLESHOOTING POWER-SUPPLY PROBLEMS
General Principles
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.
Note: The matrix’s backplane connectors are part of the matrix’s infrastructure
and are not serviceable by field personnel. If you determine that a problem
is in the matrix’s backplane connectors, you must send the matrix in for
repair. Backplane connector malfunctions are rare, but should be
considered as possiblities.Clear-Com will ship a spare matrix to use while
the damaged matrix is being repaired.
If you need to send any equipment back to Clear-Com, follow the procedure
described in the Warranty chapter of this manual for obtaining a return
authorization number from the Clear-Com Service Department.
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 you identify a problem in the power supplies, the backplane connectors,
or the circuit cards, you can then swap out the suspect component with a
properly functioning component to see if the problem is repaired.
