EtherDisk Diskette for the EtherLink II Adapters
Diagnostic Program Instructions Summary
Overview
--------
The diagnostic program tests the EtherLink II adapter to make sure that it
is installed correctly and functioning properly in your computer.
- The Group 1 tests check the physical components, connectors, and
circuitry of the adapter. They require only that the adapter be
installed in the computer.
- The Group 2 tests check the adapter's ability to transmit data on the
network. They require that the adapter be connected to a loopback plug
(coax version only) or to a network.
- The Group 3 tests check the adapter's ability to correctly transmit and
receive data over the network. They require that the adapter be
connected to a network on which an echo server has been set up.
Starting the Diagnostic Program
-------------------------------
The computer containing the EtherLink II adapter to be tested must be
running DOS with no network drivers or memory managers loaded.
NOTE: If this computer is an operating server, notify all users of the
server to save their work and log out from the network. The
diagnostic program disrupts the normal operation of server and
workstations, so work that is not saved may be lost.
There are two ways to start the diagnostic program:
1. Insert the EtherDisk diskette and type MENU at the prompt. Select
the option "Diagnostic and Troubleshooting Information" from the main
menu. Use the appropriate program for either the coax or the
twisted-pair version of the adapter.
If only one diagnostic program is listed, use it for either version of
the adapter. For example, the EtherLink II and EtherLink II TP adapters
use the same diagnostic program.
2. Type the following command from the root directory of the EtherDisk
diskette:
3C503 [/B:I/O BASE ADDRESS] [/S]
The brackets indicate that the /B and /S switches are optional.
If the /B switch is omitted, the diagnostic program will search through
the possible I/O base addresses to find an EtherLink II adapter to test.
Use the /B switch to specify a particular EtherLink II adapter to be
tested in a computer with multiple EtherLink II adapters installed.
Use the I/O base address of the adapter to be tested for the I/O BASE
ADDRESS.
If the /S switch is specified, the diagnostic program will test DMA
transfers using the single-byte mode. If the switch is omitted, DMA
demand mode is used.
Using the Diagnostic Program
----------------------------
When you use the diagnostic program, you will be asked to specify a DMA
channel, interrupt level, and transceiver type. Select a DMA channel and
interrupt level that do not conflict with those of any other peripherals
installed in the computer. See the SYSRESRC.TXT file in the \README
directory on the EtherDisk diskette for a list of system resources used by
other common peripherals. The ON-BOARD transceiver (BNC or RJ-45 connector) is the
default setting. EXTERNAL should be selected if an external transceiver
(AUI connector) is being used.
The menus and forms that make up the diagnostic program will guide you
through testing your EtherLink II adapter. The following keys can be used:
Key Function
--- --------
[Up-arrow] Moves highlight within menus and forms
[Down-arrow]
[Enter] Selects highlighted item
[Return]
[F1] Gives help information about the highlighted item
[Esc] Returns to previous menu or form
Stops a test
Stops echo server operation
If the adapter fails the diagnostic program, see the TROUBLE.TXT file in the
\DIAG directory on the EtherDisk diskette for troubleshooting procedures.
Further Information
-------------------
For more information about the diagnostic program and how to use it,
refer to the appropriate adapter guide. The SUPPORT.TXT file in the
\README subdirectory on the EtherDisk diskette provides information about
obtaining product support for the EtherLink II adapter. For more
information about jumper settings for the twisted-pair adapters, refer to
the TPOPTS.TXT file in the \README subdirectory.
The TROUBLE.TXT, SUPPORT.TXT, and TPOPTS.TXT files can be automatically
displayed and printed from the Menu Program.
