Network Interface Controller (NIC)

Network interface support is provided from the onboard Intel
compact component with two fully integrated GbE Media Access Control (MAC) and Physical
Layer (PHY) ports. The Intel
ports designed for 10/100/1000 Mbps operation. Refer to the Intel
Controller Datasheet (Document#: 82576) for full details of the NIC feature set.
The NIC device provides a standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE-
TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab) and is capable of transmitting
and receiving data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps.

The Intel 82576 NIC is powered off the main standby voltage rail via DC to DC Voltage
regulators for efficiency purposes. It is on standby power so the BMC can send out-of-band
management traffic over the RMII bus to the network during sleep state S5.
The NIC supports the normal RJ-45 LINK/Activity speed LEDs as well as the Proset ID function.
These LEDs are powered from a Standby voltage rail.
The link / activity LED (at the right of the connector) indicates network connection when on, and
transmit / receive activity when blinking. The speed LED (at the left of the connector) indicates
1000-Mbps operation when amber, 100-Mbps operation when green, and 10-Mbps when off.
The following table provides an overview of the LEDs.
