Hardware Connection: Check the connections between the card and the backplane. Ensure that the cables are properly connected and not damaged.
Firmware Version: Make sure you are on the 4.10.00.027 firmware.
Overheating or Dust: Overheating or dust could cause the backplane to behave strangely. Ensure that the system is clean and well ventilated.
Hardware Failure: If none of the above solutions work, it’s possible that the card or the backplane might have gone bad. In this case, you might need to replace the faulty component.
