If this test failed:
1.) The system should not be in a small enclosed
space with other equipment that generates a lot of
heat. Move the system away from walls and other
equipment.
2.) Clean or replace any dirty fan filters.
3.) Replace the fan tray beneath the card rack if the
tachometer readings are slow. Perform the Fan test
to confirm issue.
4.) Check the fan on the BEP and replace the fan if
it is not working.
5.) Replace the MRX Board if none of the above
fixes the temperature problems.
1.) Check the voltage test points on the system
boards.
2.) Replace the system boards that are out of
tolerance.
3.) Check the main power supply.
4.) Replace the main power supply if it is out of
tolerance.
1.) If the test fails to read every FPGA ver sion, check
the connection between the Host and the MRX
Board. Replace the MRX Board.
2.) If the test fails to read the GTX IF FPGA version,
check the GTX boards.
