Intel® Server Boards S5000PSL and S5000XSL TPS Functional Architecture

Revision 1.7

Intel order number: D41763-008

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.

3.5.2 MAC Address Definition

Each Intel

Server Board S5000PSL/S5000XSL 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 alphanumeric 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

stack to enable IPMI remote management over LAN. BMC LAN Channel 1 is assigned the NIC1

MAC address + 2, and BMC LAN Channel 2 is assigned the NIC2 MAC address + 2

3.6 Super I/O

Legacy I/O support is provided by using a National Semiconductor* PC87427 Super I/O device.

This chip contains all of the necessary circuitry to support the following functions:

 GPIOs

 Two serial ports

 Keyboard and mouse support

 Wake-up control

 System health support

3.6.1 Serial Ports

The server board provides two serial ports: an external DB9 serial port and an internal DH10

serial header. The rear DB9 serial A port is a fully-functional serial port that can support any

standard serial device.

Serial B is an optional port that is accessed through a 9-pin internal DH-10 header. A standard

DH10 to DB9 cable can be used to direct serial B to the rear of a chassis. The serial B interface

follows the standard RS232 pin-out as defined in the following table:
