Self-test errors (901...)
Diagnosing the faulty assembly using self test errors 901 - 912
If the instrument reports self-test errors 901 - 912, this means the processor
board is unable to correctly program or communicate with the FPGAs
(programmable chips) on the main board. In this case, further troubleshooting is
required to determine where the fault lies. The problem could be due to out of
date firmware, unseated processor board or main board, assembly failure or
processor board failure.
The following errors indicate failures that may occur during a self test:
– +901, “Self Test failed; Autocal failure”
– (1) 53200-66501 Motherboard
– +902, “Self-test failed; Main CPU power supply out of range”
– (1) 53200-66501 Motherboard
– +903, “Self-test failed; Real time clock settings lost”
– (1) RTC ‘coin’ battery (CR2032); (2) 53200-66502 front panel assy
– +904, “Self-test failed; Main CPU error accessing boot env”
– (1) P0500-63001 processor board
– +905, “Self-test failed; Failed to read FPGA Rev”
– (1) 53200-66501 Motherboard; (2) P0500-63001 processor board
– +906, “Self-test failed; FPGA Rev is less than expected”
