IV. Working Principle

V. Common Faults and Solutions

• Failure to Power On
• Fault phenomenon: The board shows no response and indicator lights remain off after power connection.
• Solutions: First, check if the external power supply is normal and if power cables are loose or damaged, ensuring power input meets the board's requirements. Then, inspect the board's power module for obvious damage (e.g., bulging capacitors, burned components) and replace the damaged module if found. If the power module is normal, try resetting the board. If the issue persists, it may be a fault in other key motherboard components, requiring professional maintenance personnel for further inspection and repair.
• Abnormal Data Transmission
• Fault phenomenon: Data loss, errors, or transmission interruptions occur during interface data transfer.
• Solutions: For Ethernet interfaces, check network cable connections, replace cables or network devices (switches, routers) for testing, and verify network configurations (IP address, subnet mask, gateway, etc.). For serial communication, check serial cables and confirm that communication parameters (baud rate, data bits, stop bits, parity) match external devices. If PCIe interface expansion devices have transmission issues, check expansion card installation and driver correctness, reinstalling drivers or replacing cards if necessary.
• Unstable System Operation
• Fault phenomenon: System freezes, restarts, or program errors occur during operation.
• Solutions: Check if system temperature is too high, ensure good heat dissipation by cleaning radiators and fans, and replace fans if needed. Use memory testing tools to check for faults and replace memory if issues exist. Investigate software conflicts and uninstall incompatible recently installed software. If ineffective, it may be a processor or key hardware fault requiring further detection.
• VME Bus Communication Failure
• Fault phenomenon: The board cannot communicate normally with other VME modules, failing to share data.
• Solutions: Check VME bus connections for firm insertion into slots and good contact. Inspect VME bus cables for damage and replace them if needed. Verify correct VME bus address settings to avoid conflicts. If the problem persists, it may be a fault in the board's VME bus interface circuit, requiring professional maintenance.
