A8 Motherboard Assembly
A8 Motherboard Assembly
The A8 Motherboard assembly is serviced as an assembly only; no component
level repair is supported. For details on the functionality of this assembly see
Chapter 3, "Assembly
Descriptions".
While the main function of the A8 Motherboard assembly is to provide the
electrical interconnections between the different electrical assemblies within the
instrument, it also provides buffering for the front panel power status LEDs and the
temperature sensitive cooling fan speed control. While failures due to the A8
Motherboard will be very infrequent it is possible that a failure in one of these
areas could be related to it.
If there is a problem with the operation of the instrument cooling fans see the
section titled
"Fan(s) Are Not Operating"
in this chapter.
