Ethrnet PLUS-16 (260-5507) Diagnostic Faxback Doc. # 5549 TP Adapter BEFORE INSTALLING THE PROGRAM A. Seat the board firmly into an expansion slot. B. Make sure the Ethernet board is on a properly terminated cable. There are three choices: 1. An AUI loopback connector. This cannot be used for the Initiate/Respond Test Messages. 2. A drop-cable connected to the AUI port with appropriate MAU transceivers and signal repeaters. 3. Connect to a properly functioning 10BaseT concentrator. B. Boot to a DOS prompt. NOTE: Network memory resident (TSR) programs and device drivers should not be loaded while the diagnostic program is active, so you may need to temporarily rename the CONFIG.SYS and AUTOEXEC.BAT files. Network software must not be loaded when running the diagnostic program. C. Screen Prompts Enter = Select: Press [Enter] to select the high- lighted option. ESC = Cancel: Pres [ESC] to back up to the previous screen. At the Main Menu, press [ESC] to exit the diagnostic program. F1 = Help: Displays additional information about any item on the menu. To return to the menu options press [ESC]. Arrow Keys: Use the arrow keys to move the cursor to the desired location. Several other function keys are used within specific menus. 1. STARTING DIAGNOSTICS A. Change to the directory with the diagnostic program - \DIAGNOSE on the software diskette. 1. Type: DIAGNOSE and press [Enter]. The Introduction Screen will appear. 2. Press [Enter] to access the Entry Menu. 3. Press [Enter] again. The "Choose a Board to Diagnose" option will be highlighted. 4. Press [Enter] to select this option. The Board Selection Menu appears with a list of available adapters displayed for your selection. B. If an error message appears, this indicates 1. An adapter board is not present, or 2. An adapter board is not responding properly. 3. If two or more adapters are installed, each should be listed in the Board Selection menu. 4. Check the I/O address for each board to verify a unique setting for each one. C. Use the arrow keys to highlight the board you want to diagnose and press [Enter] or simply type the list number to the left of the board (for instance, 1) to select the board. D. The current board parameters appear. Press [Enter] to access the Main Menu. If your adapter is configured with different parameters, the option to correct them can be accessed from this menu. 2. MAIN MENU OPTIONS A. Choose a Board to Diagnose - Used to select the adapter to be diagnosed. B. Set Configuration - Displays the configuration information received from the board. Temporary changes can be made. The permanent settings are not affected. 1. The network address and board type is at the top of the menu. 2. A list of the parameters and their current settings is shown in the middle. 3. Use the arrow keys to highlight the parameter(s) to be changed and press [Enter]. A list of optional settings will appear. Use the arrow keys to highlight the new setting and press [Enter]. The change will be displayed. A. The program will not stop a user from making an invalid selection. B. The RAM address selected here is only for the purpose of this program and has no effect on any other network software. 4. Press [F10] to save the changes or press [ESC] to exit without change. 5. Reset or turn off your computer after using Diagnose. C. Basic Adapter Test - Runs a diagnostic test on the selected adapter. 1. Used to verify the major functions of the adapter are operating properly, the program notifies you of any errors and suggests actions to take to solve the problem. 2. Tests are performed on I/O Port Accessibility, LAN Address ROM, On-board RAM, Network Controller Registers, On-Board ROM (if installed), Internal Loopback, Interrupt Generation. 3. The test has failed if: A. An error message displays at the bottom of the screen in a red box. B. The test hangs up at a certain blinking line and never completes. The blinking line is the test that failed. 4. If either an error message or blinking line occurs, write it down. Cycle power. Use the error message or blinking line to find the problem. Common problems include: A. Not terminating an Ethernet network, or B. Hardware or software conflicts with IRQ, Base I/O, or RAM Address. 5. If the board fails, recheck the board settings, try a different BNC "T" connector and terminator, or remove other boards from the PC. D. Initiate Test Messages - Used to send messages to another node running DIAGNOSE in Responder mode. E. Respond to Test Messages - Upon selection this option waits for a Test Message to be received from another node on the same network using DIAGNOSE and running "Initiate Test Messages." All Test Messages are echoed back to the Initiator. F. Initiate/Respond to Test Messages - Are used together to verify network cabling is properly set up to transmit and receive information. 1. In order to run this test, another node on the same network must be using DIAGNOSE and have "Respond To Test Messages" running. 2. The Responder echoes the messages back and the Initiator makes sure it receives the same messages it transmitted. 3. The best test environment is two computers directly cabled, but this test can be run with any computers on the network. A. At the chosen PC on the network, select "Respond to Test Messages" from the Main Menu. Press [Enter]. A prompt appears on the screen: "Waiting to Respond to Test Messages. Press any key to stop." This unit is the Responder. B. Using a different PC, select "Initiate Test Messages" from the Main Menu. Press [F2] and all active Responders are displayed with their network addresses. Use the arrow keys to select the Responder you want to test. C. Press [Enter] to begin the test. The test will perform 1000 iterations after finding the first available Responder if a specific one has not been selected. D. If you have more than one Responder on the network, press [F2] and all active Responders are displayed with their network addresses. Select the desired Responder by using the arrow keys. E. If the error message "No Responder Found" displays, the two computers cannot communicate across the network. A common reason for this is faulty cabling, "T" connectors, or terminators that are bad. 4. When the test is complete, press [F4] at either unit to see the test results. This screen provides you with statistics on both the Initiator and Responder terminals. 5. The Show Statistics screen shows whether the Initiator and Responder passed the test. It also provides a number of function key operations. A. To update data without clearing the counter setting, press [F4]. This automatically updates as the test continues. B. To repeat the test without clearing the counter setting, press [ESC]. C. To clear these statistics, press [F6]. D. To exit this test and return to the Respond Menu, press [ESC]. E. To change the test parameters, such as the number of iterations or the test pattern, press [F6] at either the Initiate or Respond menu. -- A screen with a list of all test parameters appears. For most of these parameters, use the arrow keys to highlight the one you want changed. -- Use the [Spacebar] to change the setting. Each time the [Spacebar] is depressed, the value will change. F. To change either the test pattern or destination address field, type in the value you require. Press [ESC] to return to the Respond Menu. G. For a definition of each parameter, press [F1] at the appropriate screen. H. Select the Exit option when all diagnostic procedures have been completed and you want to return to DOS. G. Exit to Operating System - Select this option to exit the diagnostic program and return to DOS. 3. Refer to the USER.DOC file located on the software diskette for more information on how to operate the diagnostic program. (SMM/jlc-03/28/94)
