Specific Troubleshooting Examples
Troubleshooting more specific problems becomes easier when keeping these
general principles in mind. The following examples describe specific problems
and suggested solutions.
Problem: All of the power supply lights do not illuminate on one
port card.
Before repairing or replacing card, try to determine where the problem is
occurring. You can try one or both of the following options:
OPTION 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. You can send the matrix to Clear-Com for investigation or
repair. In the meantime, you can substitute another matrix for the damaged
one. Clear-Com will send you a matrix to use while the damaged one is
being repaired.
OPTION 2 Take a known good card, and insert it into the bad 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. You can send the matrix to Clear-Com for
investigation or repair. In the meantime, you can substitute another matrix
for the damaged one. Clear-Com will send you a matrix to use while the
damaged one is being repaired.
Once you have isolated the problem 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 all 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.
The following procedure helps you isolate where the trouble is occurring:
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.
• 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
