ROUBLESHOOTING
Diagnostic tests are divided into three groups:
■
The Group 1 tests check the physical components, connectors,
and circuitry on the NIC.
■
The Group 2 Network Loopback Test (for the 3C509B-TPC and
COMBO NICs only) checks to see if the NIC can transmit and
receive data through the coaxial transceiver.
■
The Group 3 test (the Echo Exchange Test) tests to see if the
NIC can transmit and receive data while on the network.
If the NIC passes the group tests successfully, the NIC is
functioning correctly. If the problem remains, look at cabling,
software, driver configuration, and issues that can affect
network functionality.
