Troubleshooting

and solutions, see the section, “General Troubleshooting.”

1.The system fails to find the Smartio CP-168U board!

C.The board(s) is (are) not properly plugged into the PCI slot.

D.The PCI slot is defective. Please try other slots until you find one that works.

E.The board itself might be defective.

2.After the system reboots, the error message “CP-168U board(BusNo=x, DevNo=x, Port1=COMx) interrupt number is invalid!” appears.

This indicates that the MOXA board was found, but the IRQ conflicts with another adapter. Make sure the MOXA board’s IRQ does not conflict with another adapter’s IRQ. Check the PCI BIOS IRQ settings and then select an available IRQ for the MOXA boards.
