Connectors

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

LEDs

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:
