Verification/Diagnostic Program

DFE-500TX Ethernet PC Card User's Guide

This test program verifies configuration of the DFE-500TX as set by the installation procedure, and assists with isolation of any faults in operation. Verification and testing procedures are optional, and will only be useful in the unusual event that there is a fault, such as an interrupt number conflict among your computer’s expansion cards. If your installation provides normal operation, you might choose to skip these procedures.

The Verification/Diagnostic Program provides two levels of testing: adapter function testing and network operation testing. Adapter testing includes three separate procedures:

a.Serial ROM Verification

b.Controller Internal Loopback test

c.Twister Layer Loopback test

Adapter testing does not require substitution of a loopback cable. All three parts of the Adapter test may be carried out with the network cable connection in place.

For the network operation test, the cable connecting your station with its supporting hub must be in place. Network test involves “broadcast” transmission of test packets from the primary station. The test cannot be fully implemented unless a second station on the LAN is available to the network operation test, in order to return the test packets to the primary station.

To run the Verification/Diagnostic Program, proceed with these steps:

Adapter Function Test

1.Insert the DFE-500TX Software Diskette in an available drive (here shown as drive A). At the DOS prompt (here shown as >), key in:

>A: \DIAG\DIAG500.EXE

and <RETURN>. The opening screen of the Verification/ Diagnostic program will appear.
