Chapter 1: Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the 5400 chipset, the X7DWA-N

motherboard provides the performance and feature set required for quad-core-

processor- or dual-core-processor-based high-end workstations with confi guration

options optimized for complex system platforms. The 5400 chipset supports single

or dual Intel Quad-Core/Dual-Core Xeon 5400/5300/5200/5100 Series processor

with front side bus speeds of up to 1.6 GHz. The chipset consists of the 5400

Memory Controller Hub (MCH) for the host bridge and the 631xESB/632xESB I/O

Controller Hub (Enterprise South Bridge 2-ESB2) for the I/O subsystem.

The Intel 5400 MCH (North Bridge)

The 5400 MCH (North Bridge) provides two FSB processing interfaces, four

fully buffered (FBD) DIMM memory channels, PCI-Express x4 bus interfaces

confi gurable to form x8 or x16 ports, an EB2 South Bridge Interface (ESI) and

SMBus Interfaces for system management, and DIMM Serial Presence Detect

(SPD). The PCI-Express x4 interfaces can be confi gured to form x8 or x16 ports

that can operate up to Gen-2 speeds in x16 confi guration for enhanced graphics

applications.

The Intel 631xESB/632x ESB I/O Controller Hub-ESB2 (South Bridge)

The 631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2) integrates

an Ultra ATA 100 Controller, six Serial ATA host controller ports, one EHCI host

controller, six USB 2.0 ports, an LPC interface controller, and a fl ash BIOS inter-

face controller. Additionally, the ESB 2 chip also contains a PCI interface controller,

Azalia/ '97 digital controller, integrated LAN controller, an ASF controller and an

ESI for communication with the MCH. The Intel ESB2 offers the data buffering

and interface arbitration capabilities required for a high-end system to constantly

operate effi ciently and maintain peak performance.

Compliant with the ACPI platform, the ESB2 supports the Full-On, Stop-Grant,

Suspend-to-RAM, Suspend-to-Disk, and Soft-Off power management states.

Combined with the functionality offered by the onboard LAN controller, the ESB2

also supports alert systems for remote management.

With the 5400 chipset built in, the X7DWA-N offers a superb solution for intense

computing and complex I/O environments, and is ideal for high-end server sys-

tems.

X7DWA-N User's Manual

1-3 Special Features

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 Advanced BIOS Setup section to change the setting. The

default setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X7DWA-N. All

have an onboard System Hardware Monitor chip that supports PC health moni-

toring.

Onboard Voltage Monitors for the CPU Cores, Chipset Voltage,
Memory Voltage, +1.8V, +3.3V, +5V, +12V, -12V, +3.3V Standby,
+5V Standby and Vbat

An onboard voltage monitor will scan these voltages continuously. Once a volt-

age becomes unstable, a warning is given or an error message is sent to the

Fan Status Monitor with Firmware Control

The PC health monitor can check the RPM status of the cooling fans. The onboard

CPU and chassis fans are controlled by Thermal Management via BIOS (under

Hardware Monitoring in the Advanced Setting).

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will

increase fan speed whenever the CPU temperature reaches a user-defi ned

threshold. The onboard chassis thermal circuitry can monitor the overall system

temperature and alert users when the chassis temperature is too high.

CPU Fan Auto-Off in Sleep Mode

When the power is turned on, the CPU fan becomes active. It stops to operate

when the system enters Standby mode. When in sleep mode, the CPU will not

run at full power, thereby generating less heat.

CPU Overheat LED

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

in the BIOS. This allows the user to defi ne an overheat temperature threshold.

When the CPU temperature reaches the user-predefi ned threshold, the warning

LED is activated.

Chapter 1: Introduction

System Resource Alert

This feature is available when used with Supero Doctor III in the Windows OS

environment or used with Supero Doctor II in Linux. Supero Doctor is used to

notify the user of certain system events. For example, if the system is running

low on virtual memory and there is insuffi cient hard drive space for saving the

data, you can be alerted of the potential problem. You can also confi gure Supero

Doctor to provide you with warnings when the system temperature goes beyond

a pre-defi ned range.

1-5 ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -

cation defi nes a fl exible and abstract hardware interface that provides a standard

to integrate power management features throughout a PC system, including its

hardware, operating system and application software. This enables the system

to automatically turn on and off peripherals such as CD-ROMs, network cards,

hard disk drives and printers. This also includes consumer devices connected to

the PC such as VCRs, TVs, telephones and stereos.

In addition to enabling operating system-directed power management, ACPI pro-

vides a generic system event mechanism for Plug and Play and an operating- sys-

tem-independent interface for confi guration control. ACPI leverages the Plug and

Play BIOS data structures while providing a processor architecture-independent

implementation that is compatible with Windows 2000, Windows XP, Windows

2003, Windows 2003 Servers and Windows Vista.

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 CPU is in the S1 mode,

the Power LED blinks every second. When in the S3 mode, the Power LED will

blink every 5-second. When the user presses any key, the CPU will wake-up and

the LED will automatically stop blinking and remain on.

Main Switch Override Mechanism

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

suspend button to make the system enter SoftOff state. The monitor will be sus-

pended 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

power button for 4 seconds. This option can be set in the Advanced Setup section

of the BIOS Setup routine.

1-11

X7DWA-N User's Manual

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem ringing

when the system is in the SoftOff state. Note that external modem ring-on can

only be used with an ATX 2.01 (or above) compliant power supply.

Wake-On-LAN (WOL)

Wake-On-LAN is defi ned as the ability of a management application to remotely

power up a computer that is powered off. Remote PC setup, up-dates and asset

tracking can occur after hours and on weekends so that daily LAN traffi c is kept

to a minimum and users are not interrupted. The motherboard has a 3-pin header

(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has

WOL capability. In addition, an onboard LAN controller can also support WOL

without any connection to the WOL header. The 3-pin WOL header is to be used

with a LAN add-on card only.

Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.

1-6 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.

The X7DWA-N can only accommodate 24-pin ATX power supplies. Although

most power supplies generally meet the specifi cations required by the CPU, some

are inadequate. You should use one that will supply at least 500W of power. In

addition, the 12V 4-pin power and the 12V 8-pin are also required for adequate

power supply to the system. Also your power supply must supply 1.5A for the

Ethernet ports.

It is strongly recommended that you use a high quality power supply that meets

ATX power supply Specifi cation 2.01 or above. It must also be SSI compliant

(Refer to the web site at http://www.ssiforum.org/ for more information). Addition-

ally, in areas where noisy power transmission is present, you may choose to install

a line fi lter to shield the computer from noise. It is recommended that you also

install a power surge protector to help avoid problems caused by power surges.

1-7 Super I/O

The disk drive adapter functions of the Super I/O chip include a fl oppy disk drive

controller that is compatible with industry standard 82077/765, a data separator,

write pre-compensation circuitry, decode logic, data rate selection, a clock genera-

tor, drive interface control logic and interrupt and DMA logic. The wide range of

functions integrated onto the Super I/O greatly reduces the number of components

1-12

Chapter 1: Introduction

required for interfacing with fl oppy disk drives. The Super I/O supports 360 K, 720

K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500

Kb/s or 1 Mb/s. It also provides two high-speed, 16550 compatible serial com-

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

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 support

higher speed modems.

The Super I/O supports one PC-compatible printer port (SPP), Bi-directional

Printer Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port

(ECP).

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

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

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

to reduce power consumption.

2-1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent

damage to your system board, it is important to handle it very carefully. The fol-

lowing procedures are generally suffi cient to protect your equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the board from the antistatic

bag.

• Handle the board by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the motherboard and peripherals back into their antistatic bags when not

in use.

• For grounding purposes, make sure your computer chassis provides excellent

conductivity between the power supply, the case, the mounting fasteners and

the motherboard.

• Use only the correct type of onboard CMOS battery as specifi ed by the

manufacturer. Do not install the onboard battery upside down to avoid possible

explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When

unpacking the board, make sure the person handling it is static protected.

2-2 Motherboard Installation

Note: Be sure to mount the motherboard into the chassis before you install the

CPU onto the motherboard.

All motherboards have standard mounting holes to fi t different types of chassis.

Make sure that the locations of all the mounting holes for both motherboard and

chassis match. Make sure that the metal standoffs click in or are screwed in tightly.

Then, use a screwdriver to secure the motherboard onto the motherboard tray.

Note: some components are very close to the mounting holes. Please take pre-

cautionary measures to prevent damage to these components when installing the

motherboard to the chassis.

2-4 Installing DIMMs

Note: Check the Supermicro web site for recommended memory modules.

CAUTION

Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage. Also Note that the

memory is interleaved to improve performance (see step 1).

DIMM Installation (See Figure 2-2)

1. Insert the desired number of DIMMs into the memory slots, starting with Bank

1. (Refer to the Memory Confi guration Table below for more details.)

2. Insert each DIMM module vertically into its slot. Pay attention to the notch along

the bottom of the module to prevent inserting the DIMM module incorrectly.

3. Gently press down on the DIMM module until it snaps into place in the slot.

Repeat for all modules (see step 1 above).

Memory Support

The X7DWA-N supports up to 64 GB fully buffered (FBD) ECC DDR2 800/667/533

in 8 DIMMs. Populating DIMM modules with a pair (or pairs) of memory modules

of the same type and same size will result in interleaved memory. For best per-

formance, please install (a) pair(s) of DIMM modules of the same type in both

Branch 0 and Branch 1.
