Self-Tests Error Numbers and Messages
A failure can generated multiple error messages. The earliest message
generated should be considered the primary cause of failure.
Note Some self test messages include a channel number. The channel number,
n, will be replaced with the number 1 or 2 depending upon which channel
failed.
* Refer to Self-Test Errors 605 - 609, on page 147 for additional information
about troubleshooting these errors.
Error Message and Meaning Probable Cause
601 Self-test failed; real time clock settings lost
This error indicates real time clock's date-time settings were lost. This is
most likely due a disconnected or discharged RTC battery (coin cell found
on the front panel board). This error can also occur if the processor board
is removed and reinserted into the front-panel assembly. Note this error
condition is captured at power-on, and will be reported by self-test until the
problem is corrected and power is cycled.
RTC Battery
602 Self-test failed; main CPU power supply out of range
This error indicates the processor board detected that one of its supplies
was +/-10% out range of the nominal voltage.
Processor Board
603 Self-test failed; main CPU error accessing boot env
This error indicates the processor wasn't able to access its boot
parameters from flash. This could be due to out of date firmware, or a
problem on the processor board.
Processor Board
604 Self-test failed; front panel processor ping failed
This error indicates the processor board tried to read the front panel
revision code and received a 0. This could be due to an un-programmed
front panel processor, an unseated processor board, or a defective front
panel processor.
Front Panel Board
605 Self-test failed; waveform FPGA not programmed
This error indicates the processor was unable to program the waveform
FPGA (U1005) at boot-up. If this error is reported, the hardware will not
work properly.
