Troubleshooting
The 3C905C-TX Card Does Not Work
If your network interface does not work, try the following:
1
Check that:
•
The card is correctly installed (refer to “Installing the
Network Interface Card” on page 8.)
•
The LAN-specific fields in the HP PC
Setup
utility are
correctly set ( “Updating LAN-specific Fields in the HP
PC Setup Utility” on page 10.)
•
The software installation steps have been followed
( “Software Installation Procedure” on page 11.)
2
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.
3
Check that either the 10 LNK or 100 LNK green LED on the
3C905C-TX NICs rear panel is on ( “3C905C-TX NIC
Specifications” on page 22.) 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.
4
For NT 4.0 systems, check that your Service Pack has been
reinstalled. In case of doubt, reinstall the Service Pack. On some
platforms you also need to reinstall certain drivers after installing
the Service Pack. Refer to your PC documentation for more
information.
The NIC Doctor Diagnostics Do Not Work
If your network interface card seems to be operating correctly but
you cannot use the NIC Doctor, you might you might be using an
older version of the driver software. Refer to “Frequently Asked
Questions” on page 18 for more information about correctly
installing the driver software.
