Starting the Diagnostic Program 4-5 Setting Up an Echo Server To test 10 Mbps operation of the 10/100BASE-T4 PCI adapter, use a computer as an echo server that contains an EtherLink III adapter or another 10/100BASE-T4 PCI adapter. To test for 100 Mbps operation of the 10/100BASE-T4 PCI adapter, use another Fast EtherLink PCI adapter in the computer being used as the echo server. In either case, select the Echo Server menu item under the Test menu, and click Start to make the computer an echo server. If you are setting up an echo server on a computer with a 10 Mbps 3Com adapter other than an EtherLink III adapter, follow these steps: 1 Select a computer to use as an echo server. 2 Insert the EtherDisk diskette for the installed adapter in a floppy drive. The EtherDisk diskette that accompanied the adapter contains the diagnostic program. 3 Start the diagnostic program on the echo server. The diagnostic program that you use depends on the adapter board that is installed in the echo server. After the system prompt of the drive containing the Configuration and Diagnostic Program, enter the name of the program (3CXXX), as indicated in Table 4-1. The diagnostic programs listed in Table 4-1 come on the EtherDisk diskette that accompanies the adapter. 4 From the main menu, select Echo Server Setup. The program notifies you that your computer is now set up as an echo server. 4-6 CHAPTER 4: PERFORMING TROUBLESHOOTING AND DIAGNOSTIC TESTS Table 4-1 Adapter and Diagnostic Program Names (10 Mbps Adapter Only) Diagnostic Program Name Adapter 3C503 EtherLink IIa or II TP EtherLink II/16 or II/16 TP 3C505 EtherLink Plusa 3C507 EtherLink 16 or EtherLink 16 TP 3C5X9CFG EtherLink III family 3C523 EtherLink/MC 3C523TP EtherLink/MC TP 3C527 EtherLink/MC 32 3C589CFG EtherLink III PC Card family 3C59XCFG EtherLink III PCI/EISA Bus Master family Starting the Group 3 Test To run the Group 3 test on a Fast EtherLink PCI adapter, follow these steps: 1 Start the Configuration and Diagnostic Program. This program must be on the computer containing the adapter you want to test. 2 Select Test Setup from the Test menu. 3 Select Group 3 from the Group Select box. 4 Enable the Group 3 test by highlighting Enable Group. 5 Select OK and press [Enter]. 6 Go to the Run dialog box to start the tests. 7 After the test is completed: a End the program on the echo server. b Exit the diagnostic program. Getting Help If a Test Fails 4-7 Getting Help If a Test Fails If any test fails, you can get additional information as follows: 1 Highlight the test that failed in the Run Tests dialog box and press [Enter]. 2 Highlight the Zoom button and press [Enter]. If the diagnostic tests fail, the adapter may not be defective. The problem may be caused by incorrect option settings, option settings that conflict with the settings of other boards, or improper installation. Complete the following steps to test the adapter further. CAUTION: Make sure to turn the power off and disconnect all cables from the adapter before inserting or removing it from the computer. ¦ Check the adapter installation by reviewing the installation instructions in Chapter 2. Make sure the adapter is seated correctly in the slot. ¦ Inspect all cables and connections. ¦ Make sure that the PCI slot containing the adapter is activated. PCI computers allow PCI slots to be activated or deactivated through the computer‘s BIOS setup, or in some cases, with a special PCI utility. Refer to your computer documentation for information about activating PCI slots. In addition, bus mastering is not supported on all PCI slots in all computers. The Fast EtherLink PCI adapter provides better performance in a bus master slot, but will work in a non-bus master slot. Refer to your computer documentation. The original slot may be defective. ¦ Make sure that you booted your computer under DOS version 3.1 or later, and that no device drivers or memory managers are loaded. 4-8 CHAPTER 4: PERFORMING TROUBLESHOOTING AND DIAGNOSTIC TESTS ¦ If you are running the Group 3 test, make sure that the adapter is connected to a properly cabled and inactive network and that an echo server is set up on the network. ¦ Replace the failed adapter with a working adapter and run the diagnostic tests again. If the working adapter passes all tests, the original adapter is probably defective. For information on returning products for repair, refer to Appendix D,“Technical Support.” ¦ Install the adapter in another functioning PCI computer and run the tests again. Your computer may be defective. If the adapter passes the tests in the second computer, contact the reseller or manufacturer of the original computer. ¦ Replace all other PCI adapters from the computer and run the tests again. If the tests pass, the other PCI adapters may be causing contention. ¦ If you experience problems that occur only when using the AutoLink program, display or print the AUTOLINK.LOG file as follows: ¦ To display the file, type: type autolink.log | mor...
