           EtherDisk Diskette for the EtherLink/MC Adapters
               Diagnostic Program Instructions Summary



Overview
--------

The diagnostic program for the EtherLink/MC adapter is designed to make sure
that the adapter is installed correctly and functioning properly in your
computer.  Three groups of diagnostic tests are available:

-  The Group 1 tests check the physical components, connectors, and circuitry
   of the adapter and 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 and 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 and require that the adapter be connected to 
   a network where an echo server has been set up.  

   NOTE:  If Group 3 tests are running while the computer is connected to an
          active network, intermittent packet exchange failures may occur 
          before the tests are done.  These failures can be avoided by
          running Group 3 tests on an inactive network in which only the 
          computer being tested and the echo server are connected.


Starting the Diagnostic Program
-------------------------------

The computer containing the EtherLink/MC adapter to be tested must be running
DOS.  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 the server, and work that is not saved may
be lost.  The diagnostic tests do not function properly if you run them
after booting your system with NetBIOS installed. Please start your computer
with a standard boot diskette that does not contain a network driver.

The diagnostic program can be found in the root directory on the EtherDisk
diskette.  Start the diagnostic program by issuing the following command:

     3C523 [/C] [/S]


Switches inside the brackets are optional parameters.  Input any switches 
specific to your adapter.  For example:

    - Use /C for continuous testing

    - Use /S for testing a second EtherLink/MC adapter
   
    Examples:  3C523TP
    	       3C523TP /C
               3C523TP /S
               3C523TP /S /C


Help Menu
---------

If you need help while running the diagnostic program, press [F1].


Using the Diagnostic Program
----------------------------

The menus and forms that make up the diagnostic program will guide you
through testing your EtherLink/MC adapter.  The following keys can be used
during diagnostic program execution:


     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, return to the Diagnostic 
information menu and select "Troubleshooting" for troubleshooting
procedures.


Further Information
-------------------

For more information about the diagnostic program and how it should be used,
refer to the EtherLink/MC Adapter Guide or the EtherLink/MC TP Adapter
Guide, or select "Additional Adapter Information" from the main menu.
