Power supply lights on a component
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.
Example power supply issues
Problem:
One or more power supply lights are unlit on one interface card
Before repairing or replacing card, try to determine where the problem is occurring. One or
both of the following actions can be tried:
Action 1:
Take the bad card out of the matrix, and insert it into a known good slot in
the matrix.
If the power supply lights still do not illuminate, the problem is probably in the card itself.
Repair or replace the card.
If the power supply lights illuminate, the problem may be in the matrix’s backplane
connectors, which carry electric current from the power supplies to the cards. The matrix can
be returned to Clear-Com for investigation or repair. In the meantime another matrix can be
substituted for the damaged one.
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.
Action 2:
Take a known good card, and insert it into the slot.
If the power supply lights illuminate, the problem is probably in the card. Repair or replace
the card.
If the power-supply lights do not illuminate, the problem may be in the matrix’s backplane
connectors, which carry electric current from the power supplies to the cards. The matrix
