Description of Self-Test Items 244
Troubleshooting suggestion
a If the test result is Error, restart the equipment and re-perform the self-test. If the problem
persists, recover the equipment.
b If the test result is FAIL, replace the main board.
2.14 Z0212 FPGA Temperature Test
Upper-level test item
Communication Test Between PC Module and MF FPGA
Test content
The PC reads the FPGA core temperature through the PCIe bus.
Test failure analysis
If the test result is Error, the drive malfunctions.
If the test result is FAIL, the FPGA core temperature is too high.
Troubleshooting suggestion
a If the test result is Error, restart the equipment and re-perform the self-test. If the problem
persists, recover the equipment.
b If the test result is FAIL, check whether the fans are blocked, whether the FPGA radiator is
properly assembled, and whether the heat-conducting cream and radiator are in good contact.
2.15 Z0301 Fan Speed Test
Upper-level test item
Communication Monitoring Test
Test content
Read the fan speed through the UART of the SM ARM and judge whether the current fan speed
meets the requirements.
Test failure analysis
If the test result is Error, the drive malfunctions.
If the test result is FAIL, the fans are blocked (do not rotate), or a fault is detected on the main
board.
Troubleshooting suggestion
a If the test result is Error, restart the equipment and re-perform the self-test. If the problem
persists, recover the equipment.
b If the test result is FAIL, check whether the fans rotate properly. If so, replace the main board.
2.16 Z0302 Fan Speed Adjustment Test
Upper-level test item
Communication Monitoring Test
