Introduction
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 PC.
!
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 PC.
Incorrect replacement of the lithium battery may lead to a risk of explosion. It is therefore
essential to observe the instructions in the chapter "Add-on modules“-"Replacing the
lithium battery“.
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.
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!
!
The warranty expires if the device is damaged during the installation or replacement of
system expansions. Information on which system expansions you can use is available
i
from your sales office or the customer service.

Introduction
Boards with electrostatic sensitive devices (ESD) may be identified by labels.
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.

Add-on modules
Upgrading main memory
Two locations (bank 1 and bank 2) are available on the system board for installing memory
modules. DIMM modules (dual inline memory module) are used.
A maximum of 256 Mbytes of SDRAM memory modules may be installed. SDRAM memory
modules can be mixed.
You may only use unbuffered 3.3V modules. Buffered modules are not permitted.
!
You can only use 66 MHz or faster SDRAM memory modules!
Installing memory modules
Ê Flip the retainers to the left and right of the location outward.
Ê Insert the memory module into the appropriate location.
Ê Press the lateral holders until they snap in place.
Ê Press the lateral holders firmly against the location.
Removing a memory module
Ê Flip the holders to the right and left of the location outwards.
Ê Pull the memory module out of its location.

Upgrading the Second-level cache
The system board has a socket for second-level cache. You can install a Pipelined-Burst secondlevel cache module with 128 Kbytes, 256 Kbytes or 512 Kbytes.
To avoid damage to the system board only cache modules released by Siemens should
be used.

Ê Insert the new second-level cache module into the mounting location, making sure it snaps into
place (1).
To be able to use the second-level cache, you must set the Cache field in the Advanced /
Cache Memory menu of the BIOS Setup to Intern and Extern. You can enhance the
i
performance by setting the Cache System BIOS Area and Cache Video BIOS Area fields in the
same menu to Enabled and copying ROM sections with Cache memory regions to the cache.

Check that the memory extension is correctly aligned before you press it into the base on
the system board. The pins on the connector strip must fit exactly into the openings of the
