Preface

About This Manual

This m a n u al is written f o r s y s t em integrato r s , P C t e c hnicians a n d

knowledgeable PC users. It provides information for the installation and use of the

X7SPT-DF-D525 motherboard. This product is intended to be profession-

ally installed and serviced by a technician.

About This Motherboard

The X7SPT-DF-D525 motherboard is a uni-processor twin motherboard. Featuring

two nodes on the same board, it is a great choice for system builders who need more

computing power in the same space required for most single node solutions.

Each node of the X7SPT-DF-D525 is equipped with the Intel ATOM D525 (Dual

Core, 1.8GHz, 13W) processor and offer several conguration choices, including

memory up to 4GB (non-ECC SO-DIMM), up to 3 SATA ports, an on-board VGA,

and up to 4 USB 2.0 ports.

Manual Organization

Chapter 1 describes the features, specications and performance of the mainboard

and provides detailed information about the chipset.

Chapter 2 provides hardware installation instructions. Read this chapter when in-

stalling the processor, memory modules and other hardware components into the

system. If you encounter any problems, see Chapter 3, which describes trouble-

shooting procedures for video, memory and system setup stored in the CMOS.

Chapter 4 includes an introduction to the BIOS and provides detailed information

on running the CMOS Setup utility.

Appendix A provides BIOS Error Beep Codes.

Appendix B lists Driver Installation Instructions.

1-2 Chipset Overview

I/O Controller Hub: ICH9R

The I/O Controller ICH9R provides the data buffering and interface arbitration re-

quired for the system to operate efciently. It also provides the bandwidth needed

for the system to maintain its peak performance. The Direct Media Interface (DMI)

provides the connection between the MCH and the ICH9R. The ICH9R supports

up to six PCI-Express lanes, six Serial ATA (SATA) ports and twelve USB 2.0 ports.

In addition, the ICH9R offers the Intel Matrix Storage Technology which provides

various RAID options for data protection and rapid data access. It also supports the

next generation of client management through the use of PROActive technology in

conjunction with Intel's next generation Gigabit Ethernet controller.

Intel ICH9R System Features

The I/O Controller Hub provides the I/O subsystem with access to the rest of the

system. Functions and capabilities include:

Advanced Power Management•

SMBus 2.0 (I•

C)

SST/PECI Fan Speed Control•

SPI Flash•

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the X7SPT-DF-D525.

The motherboard has an onboard System Hardware Monitor chip that supports PC

health monitoring.

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when

AC power is lost and then restored to the system. You can choose for the system

to remain powered off (in which case you must hit the power switch to turn it back

on) or for it to automatically return to a power on state. See the Power Lost Control

setting in the BIOS chapter of this manual to change this setting. The default set-

ting is Last State.

Onboard Voltage Monitoring

The onboard voltage monitor will scan the following voltages continuously: CPU

Cores, Chipset Voltage, Memory Voltage (+1.8V), +3.3V, +3.3V standby, +5V, +12V,

and Vbat. Once a voltage becomes unstable, it will give a warning or send an error

message to the screen. The User can adjust the voltage thresholds to dene the

sensitivity of the voltage monitor by using SD III.

Fan Status Monitor with Software

The PC health monitor can check the RPM status of the cooling fans via Supero

Doctor III.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning function

in the BIOS. This allows the user to dene an overheat temperature. When this

temperature reaches the pre-dened threshold, the CPU thermal trip feature will be

activated and it will send a signal to the Speaker LED and, at the same time, the

CPU speed will be decreased.

1-4 PowerCongurationSettings

This section describes features of your motherboard that deal with power and

power settings.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will wake up and the LED will automatically stop blinking and remain on.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, it will function like a normal

keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button. When the user presses the power button, the system will enter

a SoftOff state. The monitor will be suspended and the hard drive will spin down.

Pressing the power button again will cause the whole system to wake up. During the

SoftOff state, the ATX power supply provides power to keep the required circuitry

in the system "alive." In case the system malfunctions and you want to turn off the

power, just press and hold the power button for 4 seconds. The power will turn off

and no power will be provided to the motherboard.

1-5 Power Supply

As with all computer products, a stable power source is necessary for proper and

reliable operation. It is even more important for processors that have high CPU

clock rates of 1 GHz and faster.

The X7SPT-DF-D525 accommodates 12V power through its Hot-Plug

port.

1-6 Super I/O

The Super I/O provides two high-speed, 16550 compatible serial communication

ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable

baud rate generator, complete modem control capability and a processor interrupt

system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as

well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which sup-

port higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Conguration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through a SMI or SCI function pin. It also features auto power management

to reduce power consumption.

1-7 Overview of the Nuvoton BMC Controller

The NuvotonSM Baseboard Management Controller (BMC), supports the 2D/VGA-

compatible Graphics Core with the PCI interface, Virtual Media, and Keyboard/

Video/Mouse (KVM) Redirection modules.

The Nuvoton BMC interfaces with the host system via a PCI interface to commu-

nicate with the graphics core. It supports USB 2.0 and 1.1 for remote keyboard/

mouse/virtual media emulation. It also provides LPC interface to control Super I/O

functions and is connected to the network via an external Ethernet PHY module. It

also communicates with onboard components via six SMBus interfaces, fan control,

Platform Environment Control Interface (PECI) buses, and General Purpose I/O

(T-SGPIO) ports.

The Nuvoton WPCM450 (Manufacturer P/N WPCM450RA0BX) has all the features

as described above plus IPMI 2.0 support. This particular chip is installed on the

X7SPT-DF-D525 motherboard model.

Note: Please refer to the Embedded IPMI User's Guide posted on our

website at http://www.supermicro.com/support/manuals/. You may also

1-8 Node Hot-Swapping

The X7SPT-DF-D525 supports cable-free node hot-swapping when installed in a

Supermicro 2U Twin2 Server chassis together with the cable-free hot-swap adapter

(both sold separately). Node hot-swapping enables the user to replace a mother-

board in a multi-node server without powering down the entire system. However,

cable-free node hot-swapping allows node hot-swapping without the tedious task

of unplugging and plugging back all the supporting cables between the chassis and

motherboard. This is done by mounting the motherboard on a tray and attaching

the tray's adapter to the motherboard. The adapter has a connector on its end

that plugs into the server's backplane. This serves as the connection between the

motherboard and all the components mounted in the chassis. Thus the term 'cable-

free'. It also enables the motherboard to easily slide in and out of the chassis for

easy maintenance. See the gure below for more information.
