10/100/1000Base-T NIC

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:
10/100/1000Base-T Port LED Activity
LED State
Data Blinking
On
Off
1000 On
Off
100 On
Off
10 On
Off
If all four LEDs remain lit simultaneously, the NIC driver software is either
missing or improperly installed.
