Verifying NIC Functionality

The faceplate on the 10/100/1000Base-T NIC provides an RJ-45 connector for 
connecting the NIC to another network device.

The faceplate of the 10/100/1000Base-T NIC has four LEDs: one for each port 
speed option (10Mbps, 100Mbps, and 1Gbps), to indicate which link is active, 
and one LED for data transfer status. Until the driver software is properly 
installed, all four LEDs remain lit when the server is powered on.

Once the NIC hardware and its driver software have been properly installed on 
your system, the LEDs indicate the following NIC states:

If all four LEDs remain lit simultaneously, the NIC driver software is either 
missing or improperly installed.
