High-Level Diagnostic Tools, Processes and References
Run Automatic Corrections
For the procedure see “Automatic Corrections procedure” on page 23.
Error messages appear in a box at the top of the SFP display.
They are of the form:
AutomaticCorrections: Gain constant out-of-range. Verify
field wiring removed from channel 0.
There are over 50 different varieties of these messages, all with the same
remedy:
Remove any field wiring from the channels. If all cables are removed from
the front panel and there is still a failure, the unit needs to be returned to the
factory for further evaluation and repairs (see
“Returning a module for service”
on page 7
).
Run Self Test
For the Self Test procedure, see “Conduct a Self Test” on page 20.
Error messages appear in a box at the top of the SFP.
–
" Calibration Fixture must not be connected but it is."
Check for no connections. If problem persists, see “Returning a module
for service” on page 7.
–
" DDR3 memory test failed”
Reset system and re-try test. If problem persists, see “Returning a
module for service” on page 7.
–
"Fault condition: “Overtemperture in FPGA”
Power down the system and make sure steps in “Chassis Cooling Checks”
on page 31 are in place. Bring the system up, and use the “Check Module
Temperature” on page 32 procedure with Continuous selected to monitor
FPGA temperature. If it goes over 85
o
C, return the board for evaluation
and repair. If the FPGA temperature stays below 85
o
C, re-run Self Test,
and if the Fault condition above persists, see “Returning a module for
service” on page 7.
The Self Test process includes the Automatic Corrections
algorithm. However the adjustments calculated during this
Automatic Corrections process are not saved, so running Self Test
does not eliminate the need for Automatic Corrections.

Corrections process.
