Click on the Diagnostics tab to display the 3Com diagnostic program options, as shown
in the following figure.
• NIC Diagnostics—tests the functionality of the NIC. You can run tests on the NIC,
configure NIC settings, or register the NIC using this utility.
• Connection Assistant—helps diagnose general installation or operation failures
you may experience. It provides you with knowledgebase articles and information
that may assist in troubleshooting, even without network connectivity.
• VCT (Virtual Cable Tester)—helps track down a potential open (break) in the
network cabling.
NOTE: The programs listed above launch only if the corresponding application
is installed. The installations do not occur automatically. Review Chapter 10,
“Installing and Using the 3Com Connection Assistant” and
Chapter 11, “Using the Virtual Cable Tester” for installation instructions.
