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 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.
