Verification/Diagnostic Program
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
