Mainboard D1691
Your mainboard is available in different configuration levels. Depending on the configuration chosen,
some of the hardware components described may not be available on your mainboard.
You have purchased one of the most powerful Intel Xeon®-based workstation solutions in a standard
SSI EEB v3.5 form factor.
Based on the Intel E7525 chipset, the D1691 features some state-of-the-art technologies such as
dual/single 800 MHz FSB Xeon® processor support, multiple PCI-Express buses, dual channel
DDR-II memory design, onboard PCI-Express Gigabit Ethernet port, Serial-ATA IDE ports, and
multiple USB2.0 (Universal Serial Bus) ports.
By doubling the capability of existing AGP8x designs with transfer rates of 4.0 Gigabytes per second
in each direction over a x16 PCI Express lane for graphics controllers, the onboard x16 PCI-Express
slot supports a high performance graphics infrastructure for high-end gaming or multimedia.

Important notes
With the mainboard installed you must open the system to access the mainboard. How to dismantle
and reassemble the system is described in the operating manual accompanying the system.
Connecting cables for peripherals must be adequately shielded to avoid interference.
!
Observe the safety notes in the operating manual of your system.
Incorrect replacement of the lithium battery may lead to a risk of explosion.
Components can become very hot during operation. Ensure you do not touch components
when making extensions to the mainboard. There is a danger of burns!
The shipped version of this board complies with the requirements of the EEC directive
89/336/EEC "Electromagnetic compatibility".
Compliance was tested in a typical PC configuration.
When installing the board, refer to the specific installation information in the manual for
the receiving device.
i
The warranty is invalidated if the system is damaged during the installation or replacement
of expansions. Information on which expansions you can use is available from your sales
outlet or the customer service centre.
Information about boards
To prevent damage to the mainboard, the components and conductors on it, please take great care
when you insert or remove boards. Take great care to ensure that extension boards are slotted in
straight, without damaging components or conductors on the mainboard, or any other components,
for example EMI spring contacts.
Remove the plug from the mains outlet so that system and mainboard are totally disconnected from
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.
●Never touch pins or conductors on boards fitted with ESDs.

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
D1691 supports Intel Xeon® processors in 604-pin Pin Grid Array package.
●Front Side Bus (FSB)
The processor host bus, or called Front Side Bus (FSB), always operates at 800 MHz. Choose
Intel Xeon® 800 MHz FSB processors for D1691.
The system will not be operational when installing Intel Xeon® 533 or 400 MHz FSB
processors.
●Single/Dual Processor System
D1691 board supports single or dual Intel Xeon® processors.
Single Processor System:
When only install a single processor on D1691, the processor must be installed on the CPU0
ZIF (Zero-Insertion-Force) socket.
Dual Processor System:
D1691 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
D1691 supports up to eight 240-pin 1.8-Volt DDR-II 400 Registered ECC DIMM modules. The
DDR2-400 memory modules can be using 256Mb, 512Mb and 1Mb memory chips.
DDR-I or Unbuffered DDR memory modules are not supported by D1691 design.
●Memory Installation
D1691 is based on Intel’s E7525 Tumwater chipset, which supports 144-bit wide dual memory
channels in memory interleaved scheme. System requires minimum two memory modules, as
a pair, to boot up the system.
For further information see "Installing the Memory" chapter.

A26361-D1691-Z120-1-7619, edition 5 7
Power Supply Considerations
●Power connectors
D1691 supports EPS/12V power supply unit (PSU) with two power connectors listed below.
EPS/12V Power Connectors

+12V_CPU0
+12V_CPU1
+12V_CPU1 GND
GND

GND
24-pin system power connector 8-pin CPU power connector
(split CPU power planes)
●Split processor power planes
D1691 supports dual Intel’s 800 MHz FSB Xeon® processors, which could reach up to 140
Watts per processor. (Check Intel’s web for the processor specifications.) By following SSI EEB
v3.51 specifications, D1691 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.
●Power requirements
Check your power supply specifications to ensure sufficient power currents for each power rail
based on your system configuration.
The major system components/parts power sources are listed below as reference:
Components/Parts Main Power Source Power Connectors
CPU0 +12V_CPU0 8-pin CPU power connector
