Intel

Server Board S5000PAL/S5000XAL TPS Functional Architecture

Revision 2.0

Intel order number: D31979-011

3.4 Network Interface Controller (NIC)

Network interface support is provided from the built in Dual GbE MAC features of the ESB-2 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 table below provides an overview of the LEDs.

3.4.1 Intel

I/O Acceleration Technology

Intel

I/O Acceleration Technology moves network data more efficiently through Dual-Core

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 Dual-Core 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 & virtual machine monitors, avoiding the

support risks of 3rd-party network stacks and preserving existing network requirements such as

teaming and failover.

3.4.2 MAC Address Definition

Each Intel

Server Board S5000PAL/S5000XAL has four MAC addresses assigned to it at the

Intel factory. During the manufacturing process, each server board will have a white MAC

address sticker placed on the board.

The sticker will display 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.

Two additional MAC addresses are assigned to the Baseboard Management Controller (BMC)

embedded in the ESB-2. These MAC addresses are used by the BMC’s embedded network
