Conventions
This guide uses several types of notice: Note, Caution, ESD.
Note: this notice calls attention to important features or instructions.
Caution: this notice alert you to system damage, loss of data, or risk of personal injury.
ESD: This banner indicates an Electrostatic Sensitive Device.
All numbers are expressed in decimal, except addresses and memory or register data, which are expressed in
hexadecimal. The prefix `0x' shows a hexadecimal number, following the `C' programming language convention.
The multipliers `k', `M' and `G' have their conventional scientific and engineering meanings of *103, *106and *109
respectively. The only exception to this is in the description of the size of memory areas, when `K', `M' and `G'
mean *210, *220 and *230 respectively.
When describing transfer rates, `k' `M' and `G' mean *103, *106and *109not *210 *220 and *230.
In PowerPC terminology, multiple bit fields are numbered from 0 to n, where 0 is the MSB and n is the LSB. PCI
and CompactPCI terminology follows the more familiar convention that bit 0 is the LSB and n is the MSB.
Signal names ending with an asterisk (*) or a hash (#) denote active low signals; all other signals are active high.
Signal names follow the PICMG 2.0 R3.0 CompactPCI Specification and the PCI Local Bus 2.3 Specification.
For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
Warning!
All operations on this device must be carried out by sufficiently skilled personnel only.
Caution, Electric Shock!
Before installing a not hot-swappable Kontron product into a system always ensure that your mains power
is switched off. This applies also to the installation of piggybacks. Serious electrical shock hazards can
exist during all installation, repair and maintenance operations with this product. Therefore, always unplug
the power cable and any other cables which provide external voltages before performing work.

Special Handling and Unpacking Instructions
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care must be taken
during all handling operations and inspections of this product, in order to ensure product integrity at all
times
Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it
is otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station
is not guaranteed, it is important for the user to be electrically discharged before touching the product with his/her
hands or tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,
jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the board is not
placed on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and
damage the batteries or conductive circuits on the board.
General Instructions on Usage
In order to maintain Kontron’s product warranty, this product must not be altered or modified in any way. Changes
or modifications to the device, which are not explicitly approved by Kontron and described in this manual or
received from Kontron’s Technical Support as a special handling instruction, will void your warranty.
This device should only be installed in or connected to systems that fulfill all necessary technical and specific
environmental requirements. This applies also to the operational temperature range of the specific board
version, which must not be exceeded. If batteries are present, their temperature restrictions must be taken into
account.
In performing all necessary installation and application operations, please follow only the instructions supplied
by the present manual.
Keep all the original packaging material for future storage or warranty shipments. If it is necessary to store or
ship the board, please re-pack it as nearly as possible in the manner in which it was delivered.
Special care is necessary when handling or unpacking the product. Please consult the special handling and
unpacking instruction on the previous page of this manual.

Chapter 2 - Installation
The VX3910 has been designed for easy installation. However, the following standard precautions, installations
procedures, and general information must be observed to ensure proper installation and to preclude damage
to the board, other system components, or injury to personnel.
2.1 Safety Requirements
The following safety precautions must be observed when installing or operating the VX3910. Kontron assumes
no responsibility for any damage resulting from
Due care should be exercised when handling the board due to the fact that the heat sink can get very hot.
Do not touch the heat sink when installing or removing the board.
In addition, the board should not be placed on any surface or in any form of storage container until such
time as the board and heat sink have cooled down to room temperature.
Be careful when inserting or removing the VX3910. The SFP cages have sharp edges which might lead to
injuries.
ESD Equipment!
This VPX board contains electrostatically sensitive devices. Please observe the necessary precautions to
avoid damage to your board:
- Discharge your clothing before touching the assembly. Tools must be discharged before use.
- When unpacking a static-sensitive component from its shipping carton, do not remove the component's
antistatic packing material until you are ready to install the component in a computer. Just before
unwrapping the antistatic packaging, be sure you are at an ESD workstation or grounded. This will
discharge any static electricity that may have built up in your body.
- When transporting a sensitive component, first place it in an antistatic container or packaging.
- Handle all sensitive components at an ESD workstation. If possible, use antistatic floor pads and
workbench pads.
- Handle components and boards with care. Don't touch the components or contacts on a board. Hold a
board by its edges or by its metal mounting bracket.
- Do not handle or store system boards near strong electrostatic, electromagnetic, magnetic, or
radioactive fields.
