The 3C905B-TX Card Does Not Work

If your network interface does not work, try the following:

•Check that:

•The card is correctly installed (refer to “Installing the Network Interface Card” on page 7).

•The LAN-specific fields in the HP PC Setup utility are correctly set (refer to “Updating LAN-specific Fields in the HP PC Setup Utility” on page 9).

•The software installation steps have been followed (refer to “Software Installation Procedure” on page 10).

•Check the network cables. In particular, check that the network cable connections are secure and that the cables are not damaged. If you find any loose connections or damaged cables, fix them and then see if your PC can communicate on the network.

•Check that either the 10 LNK or 100LNK green LED on the 3C905B-TX NIC’s rear panel is on (refer to “3C905B-TX NIC Specifications” on page 16). The green LED on the card’s rear panel is off when there is no network link, for example, when the LAN cable is not connected to the network HUB.

•For NT 4.0 systems, check that your Service Pack has been reinstalled. In case of doubt, reinstall the Service Pack.
