11.2.2
Hot patchability
The
front panels
of CPU cards and interface cards (not
rear panels
), and all Euro Cassette
power supplies are
hot patchable
– that is, they can be plugged in or removed from the
matrix while the power is on, and they will be neither damaged, nor will they cause damage
to the system.
In addition, the system smoothly incorporates a newly added card. Sometimes re-inserting a
CPU card can reset the matrix. Replace CPU cards during maintenance down times if
possible.
11.2.3
Onboard processors
If one analog port interface malfunctions, the malfunction will normally affect only the panels
connected to that analog port interface. The malfunction should not affect any other cards or
panels in the system. In all cases, removing a faulty card affects only the devices connected
to that card.
11.2.4
Fail-Safe communication
In the event of a CPU card failure, the second CPU card takes over operation of the system,
while the first card is repaired or replaced.
11.3 Troubleshooting
When attempting to identify the cause of the trouble, it is helpful to begin with the two most
basic areas which cause malfunctions:
•
The flow of electric current from the power supplies to the cards.
•
The flow of data between the program software, the circuit cards, and the attached
audio devices.
11.3.1
Troubleshooting power supply problems
Electric current in the matrix starts at the power supplies, travels through the matrix’s
backplane connectors, and then travels to the circuit cards themselves. When power-supply
problems occur, those three areas—the power supplies, the backplane connectors, and the
circuit cards—should be explored to identify where the trouble is occurring. Solving power-
supply problems starts with identifying the specific component causing the problem.
The matrix’s backplane connectors are part of the matrix’s infrastructure and are not
serviceable by field personnel. If it is determined that a problem is in the matrix’s backplane
connectors, the matrix must be returned for repair. Backplane connector malfunctions are
rare, but should be considered as possibilities.
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.
