Introduction

1-2 Chipset Overview

Built upon the functionality and the capability of the E7525 Tumwater
chipset, the X6DAL-B2/X6DAL-TB2 motherboard provides the performance
and feature set required for dual processor-based servers, with configura­tion options optimized for communications, presentation, storage, computa­tion or database applications. The Intel E7525 Tumwater chipset consists
of the following components: the E7525 Tumwater Memory Controller Hub
(MCH), and the 6300ESB (Hance Rapids) I/O Controller Hub (Hance Rapids
ICH).

The E7525 Tumwater MCH supports single or dual Xeon EM64T (Nocona)
processors with Front Side Bus speeds of 800 MHz. Its memory controller
provides direct connection to two channels of registered DDRII 400 with a
marched system bus address and data bandwidths of up to 2.67 GB/s per
channel. The E7525 Tumwater also supports the new PCI Express high
speed serial I/O interface for superior I/O bandwidth. These interfaces
support connection of the MCH to a variety of other bridges that are com­pliant with the PCI Express Interface Specification. The MCH interfaces
with the 6300ESB (Hance Rapids) ICH I/O Controller Hub via HI 1.5 Hub
Interface. The 6300ESB provides two PCI bus interfaces that can be con­figured for standard PCI 2.2 protocol, as well as the enhanced high-fre­quency PCI-X protocol.

6300ESB (Hance Rapids) ICH System Features

In addition to providing the I/O subsystem with access to the rest of the
system, the Hance Rapids ICH I/O Controller Hub integrates many I/O
functions.

The Hance Rapids ICH I/O Controller Hub integrates: 2-channel Ultra ATA/
100 Bus Master IDE Controller, two Serial ATA (SATA) Host Controllers,
SMBus 2.0 Controller, LPC/Flash BIOS Interface, PCI-X (66MHz)/PCI-Express
(x16 at 4GB/s) Interface, PCI 2.2 Interface and System Management Con­troller.

Introduction

X6DAL-B2/X6DAL-TB2 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 power­on state. See the Power Lost Control setting in the Advanced BIOS Setup
section to change this setting. The default setting is Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the X6DAL-B2/
X6DAL-TB2. All have an onboard System Hardware Monitor chip that sup­ports PC health monitoring.

Onboard Voltage Monitors for the CPU Cores, Chipset
Voltage, +3.3V, +5V, +12V, -12v, +3.3V Standby, +1.8V (for
DRAM), +1.5V Standby, +1.2V

An onboard voltage monitor will scan these voltages continuously. Once a
voltage becomes unstable, a warning is given or an error message is sent
to the screen (only when SuperDoctorIII is installed and configured). Users
can adjust the voltage thresholds in SuperDoctorIII.

Environmental Temperature Control via Supero DoctorIII

The thermal control sensor monitors the CPU temperature in real time and
will increase the speed of the thermal control fan whenever the CPU tem­perature exceeds a user-defined threshold. The overheat circuitry runs
independently from the CPU. It can continue to monitor for overheat condi­tions even when the CPU is in sleep mode. Once it detects that the CPU
temperature is too high, it will automatically increase the speed of the ther­mal control fan to prevent any overheat damage to the CPU. The onboard
chassis thermal circuitry can monitor the overall system temperature and
alert users when the chassis temperature is too high.

Chapter 1: Introduction

1-11

Introduction

TM2/CPU VRM Overheat

When the CPU reaches 700 C and above (Overheating), the CPU will slow
down and CPU Voltage will decrease to reduce CPU power consumption
and CPU VRM heat dissipation.

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 define an overheat tempera­ture. When the temperature goes beyond the predefined threshold, the
warning LED is triggered and the fans will speed up.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to
120W current and auto-sense voltage IDs ranging from .8375V to 1.6V.
This will allow the regulator to run cooler, and thus make the system more
stable.

1-5 ACPI Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible 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. This also
includes consumer devices connected to the PC such as VCRs, TVs, tele­phones and stereos.

In addition to enabling the operating system-directed power management,
ACPI provides a generic system event mechanism for Plug and Play and an
operating system-independent interface for configuration control. ACPI le­verages the Plug and Play BIOS data structures, while providing a proces­sor architecture-independent implementation that is compatible with the Win­dows 2000, Windows XP and Windows 2003 operating systems.

Introduction

X6DAL-B2/X6DAL-TB2 User's Manual

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 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 (WOR)

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 2.02 (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 X6DAL-B2/X6DAL-TB2 accommodates ATX power supplies. Although
most power supplies generally meet the specifications required by the CPU,
some are inadequate. You should use one that will supply at least 420 W of
power. In addition, a +12V, 8-pin CPU power supply and a +12V, 4-pin Aux.
power supply are also required for high-load configurations. Also your
power supply must supply 1.5A for the Ethernet ports.

NOTE: In addition to the 24-pin main power, a 12V 8-pin power con­nector (PW2) is required to support Intel Xeon CPUs, and a 12V 4­pin power connector (Aux. PWR) is also required for system power

consumption. Failure to provide this extra power will result in in­stability of the CPU after only a few minutes of operation. 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 Specification 2.02 or above. It must also be SSI
compliant (Refer to the website at http://www.ssiforum.org/ for more de­tails). Additionally, in areas where noisy power transmission is present,
you may choose to install a line filter 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 floppy 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 generator, 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 floppy 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 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 Con­figuration and Power Interface), which includes support of legacy and ACPI
power management through an SMI or SCI function pin. It also features auto
power management to reduce power consumption.

2-1 Static-Sensitive Devices

Electric-Static-Discharge (ESD) can damage electronic components. To pre­vent damage to your system board, it is important to handle it very carefully.
The following measures are generally sufficient 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 specified 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

X6DAL-B2/X6DAL-TB2 User's Manual

IMPORTANT: Always connect the power cord last and always remove it
before adding, removing or changing any hardware components. Make
sure that you install the processor into the CPU socket before you install
the CPU heatsink. Note that for the X6DAL-B2/X6DAL-TB2 you need to
install the Xeon mounting plate under the board.

2-2 Xeon EM64T Processor and Heatsink Installation

When handling the processor package, avoid placing direct
pressure on the label area of the fan. Also, do not place the
motherboard on a conductive surface, which can damage the
BIOS battery and prevent the system from booting up.

!

CPU Installation

1. Lift the lever on the CPU socket:

lift the lever completely as shown
on the picture on the right;
otherwise, you will damage the
CPU socket when power is
applied. (Install CPU1 first.)

2. Insert the CPU in the socket,

making sure that pin 1 of the CPU
aligns with pin 1 of the socket
(both corners are marked with a
triangle). When using only one
CPU, install it into CPU socket #1
(Socket #2 is automatically disabled
if only one CPU is used).

3. Press the lever down until

you hear the *click* so you
can be sure that the CPU is
securely installed in the CPU
socket.

2. Place the heatsink on top of the

CPU so that the four mounting holes
are aligned with those on the retention
mechanism.

3. Screw in two diagonal screws (ie

the #1 and the #2 screws) until just
snug (-do not fully tighten the screws
to avoid possible damage to the CPU.)

4. Finish the installation by fully

tightening all four screws.

2-3 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

DIMM #1A. The memory scheme is interleaved so you must install two
modules at a time, beginning with DIMM #1A, then DIMM #1B, and so on.

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 X6DAL-B2/X6DAL-TB2 supports up to 12GB of Reg. ECC DDRII 400
memory.

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of
chassis. Make sure that the locations of all the mounting holes for both the
motherboard and the chassis match. Although a chassis may have both
plastic and metal mounting fasteners, metal ones are highly recommended
because they ground the motherboard to the chassis. Make sure the metal
standoffs click in or are screwed in tightly. Then use a screwdriver to
secure the motherboard onto the motherboard tray.
