Using the Hardware Diagnostic Utility

Internal Loopback Test (Windows NT)
The Tech Support tab in the GA620 Driver Properties window in Windows NT displays
information on how to contact NETGEAR technical support and provides access to the
Windows NT-based internal loopback diagnostic test for the card. Please refer back to
Chapter 3 "Windows NT Driver Software" for more details.
DDTP Internal/External Loopback Test (MS-DOS)
Development and Diagnostic Test Program (DDTP), a diagnostic utility based on
MS-DOS, is included on the Model GA620/GA620T 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:
1. Boot your system in MS-DOS mode.
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.
2. Insert the Model GA620/GA620T Gigabit Ethernet Card Driver and
Documentation CD into the CD-ROM drive.
3. At the MS-DOS prompt, enter the following command:
>dos4gw e:\diag\ddtp [-c card_number] [-l log_filename] [-e]
