 NIC Board Troubleshooting

If you experience any problems with the NIC board, verify that the appropriate driver is loaded, the

proper grade of cable is used for the network connection, and the supporting hub/switch is working

properly.

1. Make sure the NIC board is fully and firmly seated in the slot connector.

2. Check the length and rating of connecting cables.

3. Make sure the NIC boards PCI slot is activated at the BIOS level. The CMOS Setup utility in

PCI computers ordinarily provides the option to activate or deactivate PCI slots.
