problem may be with the card itself, or with the backplane connectors that
carry the electric current from the power supplies to the cards. The backplane
connectors are part of the infrastructure of the matrix and are not serviceable
by field personnel.
Action 1: Swap the CPU cards. Put the first card in the second CPU slot
and the second card in the first CPU slot. The problem will follow the
card or the slot.
If the power supply lights do not illuminate on the bad card (the card with the
lights out) when it is inserted in the other CPU slot, the problem is probably in
the card.
If the power-supply lights on the bad card illuminate when the card is inserted
in the other CPU slot, the problem is probably not in the card itself. The
problem may be with the backplane connectors or power supplies.
Action 2: Check the power supplies’ alarm lights. If the 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 3: If the problem persists even after the power supply has been
replaced, the problem is in the backplane. 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 are out on both CPU cards.
The problem may be with external power supplies or internal power assembly,
since both cards appear not to be receiving power. Although less likely, the
problem may be in the matrix’s backplane connectors.
Action 1: Check the External power alarm lights or internal power
alarm light/power good light. If the 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 backplane.
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.
