Loopback diagnostic tests are available for testing the adapter hardware under Windows. These tests provide access to the adapter's internal/external diagnostics, where packet information is transmitted across the physical link (see "Diagnostics" in "Broadcom Advanced Control Suite").
The adapter has three LEDs, one for each
port speed option (10 Mbps and 100 Mbps) and one for Activity. The two-port
speed LEDs indicate active links, and the Activity LED indicates data transfer
status. Once the driver is loaded and the cables are connected properly, the
appropriate speed LED is lit and the data LED is on if data traffic is present. Before the port LEDs can provide troubleshooting information, the adapter must
be connected to the network (see "Installing the Hardware"),
and the network drivers for your particular operating system must be installed.
