3Com (R) Corporation 3C90x EtherLink PCI NIC Family Troubleshooting Information If the NIC diagnostic tests fail using the 3Com Configuration and Diagnostic program for DOS, the NIC may not be defective. Check the following: 1. Make sure that the NIC is completely seated in its slot. Review the installation instructions in the NIC's user guide. 2. If you are running the Group 2 test, make sure that the NIC is securely connected to a loopback plug or to a properly cabled network. Running Group 2 tests while connected to an active network can cause intermittent failures. These failures can be avoided by using a loopback plug or by connecting to an inactive network on which only the computer being tested is operating. 3. If you are running the Group 3 test, make sure that the NIC is securely connected to a properly cabled network and that an echo server is set up and running on the network. 4. If you are configuring the I/O base address, interrupt request level, or boot PROM base address, make sure that the settings you choose for these parameters do not conflict with any other peripheral or software program installed in the computer. For a list of system resources commonly used by other peripherals, select Commonly Used Interrupt and I/O Base Addresses from the Configuration and Diagnostic submenu. 5. Make sure that the configuration setting for the transceiver type is correct. 6. If you installed a twisted-pair NIC in your PC, check the LED on the backplate of the NIC. The LED should be checked only during or after the diagnostic tests have been run. The LED lights when there is a correct and active connection between the NIC and the hub. The LED flashes if the polarity of the connection is reversed. 7. The slot in the computer may be defective. Install the NIC in another slot and run the tests again. 8. The computer in which the NIC is installed may be defective. Install the NIC in a known functioning computer and run the tests again. 9. The components of the loopback plug you are using may be defective. Try a different loopback plug. 10. Replace the failed NIC with a known working NIC with the same configuration. Run the tests again. If the second NIC fails, something is probably wrong with the test environment, not with the NIC. (%VER TROUBLE.TXT - Troubleshooting v5.1.0)Download Driver Pack
