the mains voltage.

Be careful with the locking mechanisms (catches, centring pins etc.) when you replace the

mainboard or components on it, for example memory modules or processors.

Never use sharp objects (screwdrivers) for leverage.

Boards with electrostatic sensitive devices (ESD) are identifiable by the label shown.

When you handle boards fitted with ESDs, you must, under all circumstances,

observe the following:

● You must always discharge static build up (e.g. by touching a grounded object)

before working.

● The equipment and tools you use must be free of static charges.

● Remove the power plug from the mains supply before inserting or removing

boards containing ESDs.

● Always hold boards with ESDs by their edges.

Choose Proper Parts for Your System

Choose Proper Parts for Your System

Before you installing a system with this motherboard, make sure your major system parts meet the

following basic guidelines and requirements:

Central Processor Unit (CPU) Considerations

● Process Type and Package

D2568 supports Dual-Core Intel® Xeon® Processors 5200 Series as well as Quad-Core Intel®

Xeon® Processors 5400 Series in FC-LGA6 package for LGA771 socket.

● Front Side Bus (FSB)

The processor host bus, or called Front Side Bus (FSB), auto-operates at 1333 MHz. Choose

Dual-Core Intel® Xeon® Processors 5200 Series or Quad-Core Intel® Xeon® Processors

5400 Series with 1333 MHz FSB for D2568.

● Single/Dual Processor System

D2568 board supports one or two Dual-Core or Quad-Core Intel® Xeon® Processors.

Single Processor System:

When only install a single processor on D2568, the processor must be installed in the CPU0

socket.

Dual Processor System:

D2568 supports dual processor configurations only in which both processors operate with the

same FSB frequency, core frequency, and have the same internal cache sizes. Mixing

processors operating at different FSB frequency, core frequency, or cache sizes may cause

system non-operation or damages on processors and/or the motherboard.

Memory Considerations

● Memory Type

D2568 supports up to eight 240-pin 1.8-Volt DDR2-667 ECC FB-DIMM modules.

● Memory Installation

D2568 is based on Intel®’s 5400 Seaburg chipset, which supports 144-bit wide quad memory

channels in memory interleaved scheme. System requires minimum one memory to boot up

the system.

For further information see "Installing the Memory" chapter.

A26361-D2568-Z120-1-7619, edition 1 9


Choose Proper Parts for Your System

Power Supply Considerations

● Power connectors

D2568 is powered by a split plane PSU with six +12V-rails and 1000W continuous power. One rail is

for each processor, one for systemboard and three for peripherals (e.g. HHDs, add. 6-pin graphics

connector). There are three power connectors on this motherboard as listed below.

+12 GND

10-pin additional baseboard power connector

By following SSI EEB v3.51 specifications, D2568 is designed with two separate voltage

regulator circuits to provide the power for both onboard processors in separate power rail.

Using a power supply with a combined CPU power plane from the CPU power connector is not

allowed and may cause the system to fail to power up or damage to the power supply.

Installing the Memory

Board Installation

Before attempting to install any memory, make sure that the memory you have is compatible with the

motherboard as well as the processor. The D2568 board supports up to eight 240-pin 1.8-Volt

DDR2-667 ECC FB-DIMM modules.

Here are a few key points to note before installing memory into your D2568:

● 256MB, 512MB, 1GB, 2GB, 4GB and 8GB ECC FB-DIMM memory modules are supported

● All installed memory will be automatically detected - no need to set any jumpers

● The D2568 supports up to 64 GB of memory

● Memory modules are organized in pairs. Both modules of a pair must be of same type and

density, otherwise the memory may not be detected correctly or system instability may be

caused.

● For debug mode, one FB-DIMM module can be used plugged into DIMM1 socket

Please refer to the following table memory configuration:

Board Installation

Memory Installation Procedure

When installing memory modules, make sure the modules align properly with the memory socket.

There should be keys (small indents) on your memory modules that fit according to the keys in the

memory socket. DDR modules and sockets have only one key, which is slightly near the center of

the module/socket. The method of installing memory modules is detailed in the following diagrams.

Installing a memory module

2

► Push the holders on each side of the memory slot outwards.

► Insert the memory module into the location (1).

► At the same time flip the lateral holders upwards until the memory module snaps in place (2).

Board Installation

When installing memory, a module may require a considerable amount of force to seat

properly, although this is very rare. To avoid bending and damaging your motherboard,

place it on its anti-static bag and onto a flat surface, and then proceed with memory

installation.

You must unplug the power connector to the motherboard before performing system

hardware changes, to avoid damaging the board or expansion device.

A26361-D2568-Z120-1-7619, edition 1 17

Installing the Processor and Heatsink

Installing the processor

!

The processor socket ist covered with a protective cap to protect the spring contacts

In a warranty case the mainboard can only be taken back by Fujitsu Siemens Computers

with the protective cap secured!

Never touch the underside of the processor. Even minor soiling such as grease from the

skin can impair the processor's operation or destroy the processor.

Place the processor in the socket with extreme care, as the spring contacts of the socket

are very delicate and must not be bent.

► Remove the heat sink.

► Remove the old processor (3) from the socket.

Mounting heat sink

i

Use only the heat sink supplied with your system!

Be sure to use heat conducting material between the processor and the heat sink. If a heat

conducting pad (rubber-like foil) is already applied to the heat sink, then use it. Otherwise you must

apply a very thin layer of heat conducting paste.

Heat conducting pads can only be used once. If you remove the heat sink, you must clean it and

apply new heat conducting paste before you remount it.

► Depending on the configuration variant, you

must pull a protective foil off the heat sink or

coat the heat sink with heat conducting

paste before fitting it.

► Secure the heat sink - depending on the

model - with four screws or push it into the

mounts.

Installing Add-In Cards

Board Installation

Before installing add-in cards, please check if they are fully compatible with your motherboard.

PCI-E X16 (x16)

PCI-E X8 (x8)

PCI-E X16 (x16)

PCI-X 133

PCI-X 133

PCI32

Simply find the appropriate slot for your add-in card and insert the card firmly. Do not force any addin

cards (or anything else) into any slots if they won’t seat in place. It’s better to try another slot or

return the faulty card rather than damaging both the motherboard and the add-in card.

i

!

It’s a good practice to install add-in cards in a staggered manner, rather than directly

adjacent to each other. This allows air to more easily circulate within the chassis, providing

improved cooling for all installed devices.

You must unplug the power connector to the motherboard before performing system

hardware changes, to avoid damaging the board or expansion device.

Connecting External Devices

Connecting external devices to the motherboard is an easy task. The standard devices you should

expect to plug into the motherboard are keyboards, mouse, and printer cables. The following

diagram will detail the ATX port stack for the following board:

While the ports have been created to accept connectors in only one direction, make sure

to be careful when inserting connectors. At times, attaching connectors in the incorrect

orientation can damage, bend and or break the pins.

Installing the Power Supply

There are three power connectors on this motherboard:

● 24-pin P1 baseboard power connector (according SSI 3.51 spec)

● 8-pin processor power connector (according SSI 3.51 spec)

● 10-pin additional baseboard power connector (5xGND, 5x+12V)

Board Installation

The used power supply is a split plane PSU with six +12V-rails and delivers 1000W continuous

power. One rail is for each processor, one for systemboard and three for peripherals (e.g. HHDs,

add. 6-pin graphics connector).

The power supply has:

● one 24-pin molex-type connector for the baseboard (P1)

● one 8-pin molex-type connector for the processor power (P17)

● one 10-pin molex-type additional baseboard power connector (P18) – two yellow wires and two

black wires (only for use with this workstation)

● four 6-pin connectors for graphic adapters (P12, P13, P15, P16)

● two 8-pin connectors for graphic adapters (P11, P14)

● several HDD-, floppy- and SATA power connectors

Two onboard switching voltage regulators that are sourced by separate +12V power rails provide

each CPU’s power. This +12V CPU power source is from the onboard 8-pin square connector. The

+12V power on the 24-pin baseboard power connector and on the 10-pin additional baseboard

power connector is for system board and separated from CPU +12V regulator power source.

Therefore, the CPU will not be powered if you do not connect the 8-pin square 12V power

connector.

!

You must unplug the power supply before plugging in the power cables to motherboard

connectors.

Board Installation

Replacing lithium battery

In order to permanently save the system information, a lithium battery is installed to provide the

CMOS-memory with a current. A corresponding error message notifies the user when the charge is

too low or the battery is empty. The lithium battery must then be replaced.

!

Incorrect replacement of the lithium battery may lead to a risk of explosion!

The lithium battery may be replaced only with an identical battery or with a type

recommended by the manufacturer.

Do not throw lithium batteries into the household waste. They must be disposed of in

accordance with local regulations concerning special waste.

Make sure that you insert the battery the right way round. The plus pole must be on the

top!

The lithium battery holder exists in different designs that function in the same way.

BIOS update

When should a BIOS update be carried out?

Board Installation

Fujitsu Siemens Computers makes new BIOS versions available to ensure compatibility to new

operating systems, new software or new hardware. In addition, new BIOS functions can also be

integrated.

A BIOS update should always also be carried out when a problem exists that cannot be solved with

new drivers or new software.

How does a BIOS update work?

1. BIOS update under DOS with BIOS Flash Update bootable floppy disk

► Download the update file from our website to your PC.

► Insert an empty floppy disk (1.44 MB).

► Run the update file (e.g. 2568102.EXE).

► A bootable update floppy disk is created. Leave this floppy disk in the drive.

► Restart the PC.

► Follow the instructions on screen.

2. BIOS update under Windows with DeskFlash utility

A BIOS update can also be carried out directly under Windows with the DeskFlash utility. DeskFlash

is contained on the “Drivers & Utilites” CD (under DeskUpdate).
