Troubleshooting; Using The Hardware Diagnostic Utility - NETGEAR GA620 Reference Manual

This chapter provides information about troubleshooting the NETGEAR Model GA620 Gigabit
Ethernet Card.

Using the Hardware Diagnostic Utility

Development and Diagnostic Test Program (DDTP), a diagnostic utility based on MS-DOS, is
included on the Model GA620 Gigabit Ethernet Card Driver and Documentation CD. This utility
is used for verifying that the card hardware is functional. It performs internal and external
loopback tests and provides resulting pass/fail information. Perform the DDTP tests any time you
want to rule out or identify possible hardware problems.
To use the DDTP utility:
Boot your system in MS-DOS mode.
1.
Make sure that you do not have any plug-ins, add-ons, or resident programs installed.
If you want to run the external loopback test, connect a loopback cable between the RX port
and TX port on the network card.
Insert the Model GA620 Gigabit Ethernet Card Driver and Documentation CD into the
2.
CD-ROM drive.
At the MS-DOS prompt, enter the following command:
3.
> dos4gw e:\diag\ddtp [-c card_number] [-l log_filename] [-e]
In the command line:
• The letter e is the designation of the CD-ROM drive on your system.
• The optional -c parameter is used for specifying which card to test.
By default, DDTP tests only the first card detected in the system.
