Chapter 1: Introduction

1-3 Chipset Overview

Built upon the functionality and the capability of the 5400 chipset, the X7DWE

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

sor or dual-processor-based high-end systems with confi guration options opti-

mized for complex storage 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 bus interfaces confi gurable

to form x8 or x16 ports, an ESB2 South Bridge Interface (ESI) and SMBus Inter-

faces for system management, and DIMM Serial Presence Detect (SPD). The peak

bandwidth for each FBD channel is 8 GB/s for DDR2 800/667/533 FBD memory,

giving a total memory size of 32 GB.

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, seven external USB 2.0 ports, an LPC interface controller, and a fl ash

BIOS interface controller. Additionally, the ESB 2 chip also contains a PCI inter-

face controller, integrated LAN controller, and an ESI for communication with the

MCH. The Intel ESB2 offers the data buffering and interface arbitration capabili-

ties 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 X7DWE offers a superb solution for intense com-

puting and complex I/O environments, and is ideal for high-end server systems.

X7DWE User's Manual

1-4 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 Advanced BIOS

Setup section to change this setting. The default setting is Last State.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the X7DWE. All have

an onboard System Hardware Monitor chip that supports PC health monitoring. An

onboard voltage monitor will scan these onboard voltages continuously: CPU Core,

Chipset Voltage, Memory Voltage, +1.8V, +5V, +3.3V, +3.3V Standby, +5V Standby,

+12V, −12V and VBatt. Once a voltage becomes unstable, a warning is given or

an error message is sent to the screen. Users can adjust the voltage thresholds

to defi ne the sensitivity of the voltage monitor.

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 turn

on the thermal control fan whenever the CPU temperature exceeds a user-defi ned

threshold. The overheat circuitry runs independently from the CPU. Once it detects

that the CPU temperature is too high, it will automatically turn on the thermal fan

control to prevent any overheat damage to the CPU. The onboard chassis thermal

circuitry can monitor the overall system temperature and alert users when the chas-

sis temperature is too high.

CPU Fan Auto-Off in Sleep Mode

The CPU fan becomes active when the power is turned on. It continues to operate

when the system enters the Standby mode. When in the sleep mode, the CPU will

not run at full power, thereby generating less heat.

1-10

Chapter 1: Introduction

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning func-

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

the CPU temperature passes this threshold, both the overheat fan and the warning

LED are triggered.

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, you can also confi gure

Supero Doctor to provide you with warnings when the system temperature, CPU

temperatures, voltages and fan speeds go beyond a pre-defi ned range.

1-6 ACPI Features

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

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

way 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.

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

provides a generic system event mechanism for Plug and Play and an operating

system-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 both Windows 2000 and Windows 2003

Operating Systems.

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.

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 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

1-11

X7DWE User's Manual

the system malfunctions and you want to turn off the power, just press and hold

the power button for 4 seconds. This option can be set in the Power section of

the BIOS Setup routine.

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.

1-7 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 X7DWE can accommodate 24-pin ATX power supplies. Although most power

supplies generally meet the specifi cations required by the CPU, some are inad-

equate. In addition, the 12V 8-pin power connections are also required to ensure

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

for the Ethernet ports.

Note: The + 12V 8-pin CPU Power Connector (JPW2) is also required to

support Intel 64-bit CPUs. Failure to provide this extra power will result in

CPU PWR Failure. See Section 2-5 for details on connecting the power

supply.

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

power supply Specifi cation 2.02 or above. It must also be SSI compliant (For more

information, please refer to the website at http://www.ssiforum.org/). Additionally, in

areas where noisy power transmission is present, you may choose to install a line

1-12

Chapter 1: Introduction

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.

1-8 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

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 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

support higher speed modems.

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 dam-

age to your system board, it is important to handle it very carefully. The following

measures 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 Processor and Heatsink Installation

When handling the processor package, avoid placing direct pressure on

the label area of the fan.

Notes:

1.

Always connect the power cord last and always remove it before adding, re-

moving or changing any hardware components. Make sure that you install the

processor into the CPU socket before you install the CPU heatsink.

2.

Intel's boxed Xeon CPU package contains the CPU fan and heatsink assem-

bly. If you buy a CPU separately, make sure that you use only Intel-certifi ed

multi-directional heatsink and fan.

3.

Make sure to install the motherboard into the chassis before you install the

CPU heatsink and fan.)

4.

When purchasing an LGA 771 CPU or when receiving a motherboard with an

LGA 771 CPU pre-installed, make sure that the CPU plastic cap is in place,

and none of the CPU pins are bent; otherwise, contact the retailer immedi-

ately.

2-3 Memory Installation

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

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

1.

DIMM #1A. The memory scheme is interleaved, so you must install (a) pair(s)

of modules of the same type and same speed at a time, beginning with Bank

1, Bank 2 and so on. For optimal memory performance, please install two

modules at a time with the maximum of 4 modules as shown in the Table

below. (Refer to our website for additional memory information.)

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

2.

along the bottom of the module to prevent inserting the DIMM module incor-

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

slot. Repeat for all modules.

Explanation of
Jumpers

To modify the operation of the mother-

board, jumpers can be used to choose

between optional settings. Jumpers cre-

ate shorts between two pins to change

the function of the connector. Pin 1

is identifi ed with a square solder pad

on the printed circuit board. See the

motherboard layout pages for jumper

locations.

Note: On two pin jumpers,

"Closed" means the jumper

is on and "Open" means the

jumper is off the pins.

GLAN Enable/Disable

JPL1/JPL2 enable or disable the GLAN

Port1/GLAN Port2 on the mother-

board. See the table on the right for

jumper settings. The default setting is

Enabled.

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact

pads to prevent the accidental clearing of CMOS. To clear CMOS, use a metal

object such as a small screwdriver to touch both pads at the same time to short

the connection. Always remove the AC power cord from the system before clear-

ing CMOS.

Note: For an ATX power supply, you must completely shut down the sys-

tem, remove the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable

Watch Dog (JWD) is a system monitor that

can reboot the system when a software ap-

plication hangs. Close Pins 1-2 to reset the

system if an application hangs. Close Pins

2-3 to generate a non-maskable interrupt

signal for the application that hangs. See the

table on the right for jumper settings. Watch

Dog must also be enabled in the BIOS.

BIOS

4-1 Introduction

This chapter describes the Phoenix BIOS™ Setup utility for the X7DWE. The

Phoenix ROM BIOS is stored in a fl ash chip and can be easily upgraded using a

fl oppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been

added or deleted and might not yet be recorded in this manual. Please

refer to the Manual Download area of the Supermicro website <http://www.

supermicro.com> for any changes to the BIOS that may not be refl ected

in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and

®

PS/2

compatible computers. The Phoenix BIOS stores the system parameters,

types of disk drives, video displays, etc. in the CMOS. The CMOS memory requires

very little electrical power. When the computer is turned off, a backup battery pro-

vides power to the CMOS Logic, enabling it to retain system parameters. When the

computer is powered on, the computer is confi gured with the values stored in the

CMOS Logic by the system BIOS, which gains control at boot up.

How To Change the Confi guration Data

The CMOS information that determines the system parameters may be changed

by entering the BIOS Setup utility. This Setup utility can be accessed by pressing

the <Delete> key at the appropriate time during system boot. From the main menu,

you can access the other setup screens, such as the Security and Power menus.

Beginning with Section 4-3, detailed descriptions are given for each parameter

setting in the Setup utility.

Warning: Do not shut down or reset the system while updating BIOS to

prevent possible boot failure.
