IV. Working Principle

V. Common Faults and Solutions

• Failure to Power On
• Fault phenomenon: The board shows no response and the indicator light does not turn on after power is connected.
• 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, inspect the power module on the board for obvious signs of damage, such as bulging capacitors or burned components. If any, replace the damaged power module. If the power module is normal, try resetting the board. If the problem persists, it may be a failure of other key components on the motherboard, and professional maintenance personnel should be contacted for inspection and repair.
• Abnormal Data Transmission
• Fault phenomenon: Data loss, errors, or transmission interruptions occur when transmitting data through the interface.
• Solutions: For Ethernet interfaces, check whether the network cable connection is firm, and replace the network cable or network devices (such as switches, routers) for testing. Verify 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 installed correctly. Reinstall the driver or replace the expansion card if necessary.
• Unstable System Operation
• Fault phenomenon: Unstable phenomena such as system crashes, restarts, and program operation errors 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. Check whether there is a memory failure using a memory detection tool, and replace the memory if there is a problem. Check for software conflicts and uninstall recently installed incompatible software. If the above operations are ineffective, it may be a failure of the processor or other key hardware, requiring further detection and repair.
• VME Bus Communication Failure
• Fault phenomenon: The board cannot communicate normally with other VME modules, and data cannot be shared.
• Solutions: Check whether the VME bus connection is firm to 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 if necessary. Check whether the VME bus address setting is correct to ensure that the addresses of each module do not conflict. If the problem still exists, it may be a failure of the board's VME bus interface circuit, and professional personnel should be consulted for maintenance.
