Checking Port LEDs on the Adapter
The adapter has two LEDs, one LED for each port and indicates network
link and network activity. Before the port LEDs can provide
troubleshooting information, the adapter must be connected to the
network and the network drivers for your particular operating system must
be installed.
1. Verify that the adapter driver software has been installed and that the
adapter is connected to a network.
2. Check to see that the LEDs operate as described in Table 4.
