be substituted for the damaged one. Clear-Com will send you a matrix to

use while the damaged one is being repaired.

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.)

The following procedure helps you to isolate where the trouble is occurring:

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.

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.

• 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, you can substitute another matrix for the

damaged one. Clear-Com will send you a substitute matrix to use while the

damaged one is being repaired.

Problem: The power supply lights are out on both CPU cards.

The problem may be with power supplies, since both cards appear not to be

receiving power. Although less likely, the problem may be in the matrix’s

backplane connectors.
