LNE390A/B DIAGNOSTICS A diagnostic utility is provided to aid in installation and configuration of your Mylex LAN adapter. For the LNE390A the program file is TESTLNE.EXE For the LNE390B the program file is TESTLNEB.EXE LNE390A : Configure the board according to the users manual for a thin ethernet ( also known as 10 Base 2 ) . Make up a thin ethernet cable such as Belden RG-58/U (at least 15 feet or 5 meters in length) with a BNC tee at each end and a 50 ohm terminator on one port of each tee. Attach one tee to the LAN adapter to be tested, leaving the other end free and run the above program . This diagnostic will check the adapter base address and interrupt request line against the configuration, test the dual ported RAM and run a loop-back test with the cable and terminators attached. The test may also be conducted by selecting the AUI or the thick ethernet port. In case of thick ethernet port , a thick ethernet transceiver needs to be attached to the AUI port on the card. Also the trasceiver needs to be cabled with a thick ethernet cable and terminated at both ends of the cable for the test. Now run the test. LNE390B : Configure the board using the EISA configuration for thin ethernet ( also known as 10 Base 2 ) . Make up a thin ethernet cable such as Belden RG-58/U (at least 15 feet or 5 meters in length) with a BNC tee at each end and a 50 ohm terminator on one port of each tee. Attach one tee to the LAN adapter to be tested, leaving the other end free and run the program above. This diagnostic will check the adapter base address and interrupt request line against the configuration, test the dual ported RAM and run a loop-back test with the cable and terminators attached. The test may also be conducted by selecting the AUI or the thick ethernet port. Select Thick Ethernet port through EISA configuration . Connect a thick ethernet transceiver to the AUI port on the card. Also the trasceiver needs to be cabled with a thick ethernet cable and terminated at both ends of the cable for the test. Now run the test . In order to test out the 10 base T port , select the 10 Base T port in EISA configuraton. Connect the 10 Base T port to a 10 Base T concentrator and run the test.
