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	Description
Data	Blinking	Brief bursts of data detected on the port.
	On	Streams of data detected on the port.
	Off	No data detected on the port.
1000	On	Good 1000 Mbps (Gigabit) Ethernet link.
	Off	No 1000 Mbps link; possible link at different speed, possible
		bad cable, bad connector, or configuration mismatch.
100	On	Good 100 Mbps Fast Ethernet link.
	Off	No 100 Mbps link; possible link at different speed, possible
		bad cable, bad connector, or configuration mismatch.
10	On	Good 10 Mbps Ethernet link
	Off	No 10 Mbps link; possible link at different speed, possible bad
		cable, bad connector, or configuration mismatch.

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