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.
11.3.2 Troubleshooting data issues
The other type of problem that can occur in the system is when data is not flowing properly
between the program software, the circuit cards, and the attached panels and interfaces. A
troubleshooting sequence in this situation would be to first check cabling, then reset the card
or panel, then reset the entire system.
Analog port card (MVX-A16) Reset button
Resetting the analog port interface causes the configuration information for the interface and
its attached devices to reload to the interface from the CPU card’s operational memory
(located in its microprocessor’s RAM), thus clearing up any corruption of data that may have
occurred in the analog port interface microprocessor. The interface and all connected panels
and interfaces momentarily stop their current activity and restart. The reset button must be
pressed for more than two seconds to take effect.
If the entire system is operating except for one analog port interface, or one or more panels
connected to the interface, press the reset button for that interface only.
This button is slightly recessed from the front panel to prevent it from being accidentally
pressed. A tool such as a bent paper clip is required to press this button.
