Introduction
This manual describes the features of the system board as well as the setting options and the
extensions that you can make to the system board.
i
This system board is available in different configuration levels. Depending on the
hardware configuration of your device, it may be that you cannot find several options in
the system board, even though they are described.
You can find more detailed information in the Operating Manual of the device or in the description
"BIOS Setup".
Further information on drivers is provided in the readme files on hard disk or on the supplied drivers
diskettes or on the "Drivers & Utility" CD.

Important notes
Store this manual close to the device. If you pass on the device to third parties, you should also
pass on this manual.
!Be sure to read this page carefully and note the information before you open the device.
You cannot access the components of the system board without first opening the device.
How to dismantle and reassemble the device is described in the Operating Manual
accompanying the device.
Please note the information provided in the chapter "Safety" in the Operating Manual of
the device.
Incorrect replacement of the lithium battery may lead to a risk of explosion. It is therefore
essential to observe the instructions in the section "Replacing the lithium battery“.
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
Operating Manual or Technical Manual of the receiving device.
Connecting cables for peripherals must be adequately insulated to avoid interference.
!Components can become very hot during operation. Make sure you do not touch
components when making extensions to the system board. There is a danger of burns!
i
The warranty is invalidated if the device is damaged during the installation or
replacement of system expansions. Information on which system expansions you can
use is available from your sales outlet or the customer service center.

Information on boards
To prevent damage to the system board or the components and conductors on it, please take great
care when you insert or remove boards. Take care above all to ensure that extension boards are
slotted in straight without damaging components or conductors on the system board, or any other
components, for example EMI spring contacts.
Be especially careful with the locking mechanisms (catches, centering pins etc.) when you replace
the system board 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 observe the following
points under all circumstances:
• You must always discharge yourself (e.g. by touching a grounded
object) before working.
• The equipment and tools you use must be free of static charges.
• Pull out the power plug before inserting or pulling out boards containing
ESDs.
• Always hold boards with ESDs by their edges.
• Never touch pins or conductors on boards fitted with ESDs.

Upgrading main memory
A26361-K522-Z122-3-7419 English - 9
Upgrading main memory
The system board is equipped with two 168 pin sockets with which the main memory can be
upgraded to a maximum of 256 Mbyte. These slots are suitable for 16, 32, 8, 64 and 128 Mbyte
SDRAM memory modules of the DIMM format. Memory modules with different memory capacities
can be combined.
DIMM = Dual Inline Memory Module
SDRAM = Synchronous Dynamic Random Access Memory
!Depending on the processor type SDRAM memory modules must be designed for a
clock frequency of 66 MHz or 100 MHz or higher (meets PC100 specification).
Installing memory modules

Ê Flip the holders on each side of the relevant location outwards.
Ê Insert the memory module into the location (1).
Ê At the same time flip the lateral holders upwards until the memory module snaps in place (2).
!If you use ECC memory modules, in the Memory
/
Cache Options menu in BIOS Setup set
the Memory Parity Mode field to ECC (see section "Memory Test"). Otherwise set the
Memory Parity Mode field to Disabled.

connectors and switch blocks").

Replacing the lithium battery
A26361-K522-Z122-3-7419 English - 11
Replacing the lithium battery
!Once you have installed the system board, you should remove the battery protection (i.e.
the thin plastic plate between battery and contact spring).
Incorrect replacement of the lithium battery may lead to a risk of explosion.
The lithium battery must be replaced with an identical battery or a battery type
recommended by the manufacturer (CR2032).
Do not throw lithium batteries into the trashcan. It 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!
Ê Press the contact on the side of the battery socket outwards for about one millimeter and
remove the battery from its socket (2).
Ê Press the new lithium battery of the same type in the socket until the contact on the side
engages.
