3.6 Network Interface Controller (NIC)
Network interface support is provided from the built-in dual GbE MAC features of the Intel
®
6321ESB I/O Controller Hub in conjunction with the Intel
®
82563EB compact Physical Layer
Transceiver (PHY). Together, they provide the server board with support for dual LAN ports
designed for 10/100/1000 Mbps operation.
The 82563EB device is based upon proven PHY technology integrated into the Intel
®
Gigabit
Ethernet Controllers. The physical layer circuitry provides a standard IEEE 802.3 Ethernet
interface for 1000BASE-T, 100BASE-TX, and 10BASE-T applications (802.3, 802.3u, and
802.3ab). The 82563EB device is capable of transmitting and receiving data at rates of 1000
Mbps, 100 Mbps, or 10 Mbps.
Each Network Interface Controller (NIC) drives two LEDs located on each network interface
connector. The link/activity LED (to the right of the connector) indicates network connection
when on, and transmit/receive activity when blinking. The speed LED (to 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.

3.6.1 Intel
®
I/O Acceleration Technology
Intel
®
I/O Acceleration Technology moves network data more efficiently through Intel
®
Xeon
®
processor 5000 sequence-based servers for improved application responsiveness across
diverse operating systems and virtualized environments. Intel
®
I/OAT improves network
application responsiveness by unleashing the power of Intel
®
Xeon
®
processors 5000 sequence
through more efficient network data movement and reduced system overhead. Intel multi-port
network adapters with Intel
®
I/OAT provide high-performance I/O for server consolidation and
virtualization via stateless network acceleration that seamlessly scales across multiple ports and
virtual machines. Intel
®
I/OAT provides safe and flexible network acceleration through tight
integration into popular operating systems and virtual machine monitors, avoiding the support
risks of third-party network stacks and preserving existing network requirements such as
teaming and failover.
3.6.2 MAC Address Definition
Each Intel
®
Server Board S5400SF has four MAC addresses assigned to it at the Intel factory.
During the manufacturing process, each server board has a white MAC address sticker placed
on the board. The sticker displays the MAC address in both bar code and alpha numeric formats.
The printed MAC address is assigned to NIC 1 on the server board. NIC 2 is assigned the NIC 1
MAC address + 1.
