Troubleshooting Tips

If a diagnostic test fails, the 3C319 NIC may not be defective. The problem is usually incorrect option settings or option settings that conflict with the settings of other boards, or the 3C319 NIC may be improperly installed.

Windows NT versions 3.51 and 4.0 are not PnP-enabled operating systems. If the network driver fails to load when the 3C319 NIC is installed in a PnP PC, configure the NIC using the Configuration and Diagnostic Program on TokenDisk diskette #1. Follow the procedures in Chapter 5, “Configuring the NIC Manually,” to disable PnP for the 3C319 NIC and then configure the NIC.

If a test fails, you can get additional information by highlighting the test that failed in the Run Tests dialog box and pressing [Enter]. You can also highlight the Zoom button and press [Enter]. The program notifies you of the error and suggests actions for solving the problem.

CAUTION: Turn off the power before inserting or removing the 3C319 NIC from the PC.

Follow these steps to isolate the problem further:

1Seat the 3C319 NIC firmly in the slot.

2Inspect all cables and connections.

3Make sure that the LEDs on the 3C319 NIC and the MAU light, or that the solenoid on the MAU engages.
