Using the 3Com DOS Diagnostics Program
The DOS Configuration and Diagnostics Program includes
the diagnostic tests summarized in
Table 6
. If the NIC
passes the Group 1 and Group 3 tests, hardware failure
is ruled out. If a problem remains, look at cabling, the
connected switch, software, and other issues that affect
network functionality.
You can run the DOS diagnostics program after installing
the NIC, any time you suspect a fault.
Table 6
DOS Diagnostic Tests
Test
Description
Group 1
These tests check the physical components, circuitry,
and connectors on the NIC.
Group 2
These tests check the integrity of the on-board circuitry
and the on-board transceiver and cable connectors.
Group 3
The Group 3 tests verify the ability of the NIC to send
and receive data on the network. To run these tests,
you need two PCs with NICs installed.
