Self-Test Procedures
Error
601 Self-test failed; real time clock settings lost
Real time clock's date-time settings were lost, likely due a disconnected or dis-
charged RTC battery (coin cell found on the front panel board). Error can also
occur if processor board is removed and reinserted into front-panel assembly.
This error condition is captured at power-on, and will be reported by self-test
until the problem is corrected and power is cycled.
602 Self-test failed; main CPU power supply out of range
Processor board detected that one of its supplies was more than 10% out of the
nominal voltage range.
603 Self-test failed; main CPU error accessing boot env
Processor wasn't able to access its boot parameters from flash, possibly due to
out of date firmware, or a problem on the processor board.
604 Self-test failed; front panel processor ping failed
Processor board tried to read front panel revision code and received a 0, possibly
due to un-programmed front panel processor, unseated processor board, or
defective front panel processor.
605 Self-test failed; waveform FPGA not programmed
Processor could not program the waveform FPGA (U1005) at boot-up. The hard-
ware will not work properly.
