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
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.
Once the problem has been isolated to the card or the backplane, it is easier to take the next
step which is to repair or replace the suspect component.
Problem: The power supply lights do not illuminate on any cards in the matrix.
In this situation, the most probable problem is that the matrix's power supplies are not
sending out any electric current, since none of the cards are receiving power. Although less
likely, the problem may be in the matrix's backplane connectors.
Action 1: Check the power supplies' alarm lights. If the power alarm lights are
indicating a problem with the power supply, swap it out with a new power supply.
If this repairs the problem, the problem was in the power supply.
Action 2: If the problem persists even after the power supply has been replaced, the
problem is in the matrix's backplane connectors.
Send the matrix back to Clear-Com for repair or replacement. 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.
Problem: The power supply lights do not illuminate on one of the two CPU cards.
When the system is functioning properly, the power-supply lights on both CPU cards
illuminate. If the power-supply lights on a CPU card fail to illuminate, the problem may be
