IV. Working Principle

V. Common Faults and Solutions

• Failure to Power On
• Fault phenomenon: After powering on, the board shows no response, the indicator light does not turn on, and the system cannot start.
• Solutions: First, check whether the external power supply is normal and whether the power connection cable is loose or damaged to ensure that the power input meets the board's requirements; then check the power module on the board for obvious signs of damage such as bulging capacitors or burned components, and replace the damaged power module if any; if the power module is normal, try resetting the board; if the problem still persists, it may be that other key components on the motherboard, such as the processor or memory, are faulty, and professional maintenance personnel should be contacted for detection and repair.
• Abnormal Data Transmission
• Fault phenomenon: When transmitting data through the interface, problems such as data loss, errors, transmission interruptions, or abnormally slow transmission speed occur.
• Solutions: If using an Ethernet interface, check whether the network cable connection is firm, and try replacing the network cable or network device (such as a switch or router) for testing; check whether the network configuration is correct, including parameters such as IP address, subnet mask, and gateway; for serial communication, check whether the serial cable is normal, and confirm that the serial communication parameters (such as baud rate, data bits, stop bits, parity bit, etc.) are consistent with external devices; if data transmission problems occur with PCIe interface expansion devices, check whether the expansion card is correctly installed and whether the driver is correctly installed, and reinstall the driver or replace the expansion card if necessary. In addition, check for electromagnetic interference and ensure that the board and connection cables are kept away from strong electromagnetic sources.
• Unstable System Operation
• Fault phenomenon: Unstable phenomena such as system freezes, frequent restarts, program operation errors, or unexplained crashes occur during system operation.
• Solutions: Check whether the system temperature is too high, ensure good heat dissipation of the board, clean the dust on the radiator and fan, and replace the cooling fan if necessary; use professional memory detection tools to check for memory faults, and replace the memory if problems are found; investigate whether there are software conflicts, and uninstall recently installed incompatible software; check the working status of the processor to see if there is overheating or performance degradation; if the above operations are ineffective, it may be that the motherboard or other key hardware is faulty, and further detection and repair are required.
• VME Bus Communication Failure
• Fault phenomenon: The board cannot communicate normally with other VME modules, data cannot be shared, or frequent interruptions and errors occur during communication.
• Solutions: Check whether the VME bus connection is firm, and ensure that the board is correctly inserted into the VME slot with good contact; check whether the VME bus cable is damaged, and replace it in time if damaged; check whether the VME bus address setting is correct to ensure that the addresses of each module do not conflict; check whether the terminal resistance configuration of the VME bus is correct; if the problem still exists, it may be that the VME bus interface circuit of the board is faulty, and professional personnel should be invited for maintenance. The faulty board can be determined by the replacement method, and the problem can be gradually investigated.
