3Com Corporation 3CCFE574BT 10/100 LAN PC Card 3CXFE574BT 10/100 LAN PC Card Troubleshooting If the PC card diagnostic tests fail, the PC Card may not be defective. Check the following: 1. Make sure that the LAN card is installed in a standard Type II or Type III slot. 2. Make sure that the PC Card is completely seated in its slot. Review the installation instructions in the user documentation. 3. Make sure that your computer is running DOS 3.1 or higher and that no device drivers or memory managers are loaded. 4. Inspect all cables and connections. 5. If you are running the Echo Exchange test, make sure that the PC card is securely connected to a properly cabled network and an echo server is set up on the network. 6. If you are configuring the I/O base address or interrupt request level make sure that the settings you select for these parameters do not conflict with any other peripheral or software program installed in the computer. If your computer has Card Services, these parameters are set automatically, and you cannot change them. 7. The computer in which the PC card is installed may be defective. Install the PC Card in a known functioning computer and run the tests again. 8. Replace the failed PC card with a known working PC Card, with the same configuration. If the second PC Card fails, something is probably wrong with the test environment, not with the PC Card. %VER 1.000.000Download Driver Pack
