3.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the installation of the
WAFER-LX3 may result in permanent damage to the WAFER-LX3 and
severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the WAFER-LX3. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the WAFER-LX3, or any other electrical component is handled, the
following anti-static precautions are strictly adhered to.
Wear an anti-static wristband: - Wearing a simple anti-static wristband can
WAFER-LX3 3.5" Motherboard
help to prevent ESD from damaging the board.
Self-grounding:- Before handling the board touch any grounded conducting
material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.
Use an anti-static pad: When configuring the WA FER-LX3, place it on an
antic-static pad. This reduces the possibility of ESD damaging the
WAFER-LX3.
Only handle the edges of the PCB:-: When handling the PCB, hold the PCB
by the edges.
3.2 Unpacking
3.2.1 Unpacking Precautions
When the WAFER-LX3 is unpacked, please do the following:
Follow the anti-static precautions outlined in Section
Make sure the packing box is facing upwards so the WAFER-LX3 does not fall

5.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the installation of the
WAFER-LX3 may result in permanent damage to the WAFER-LX3 and
severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the WAFER-LX3. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the WAFER-LX3, or any other electrical component is handled, the
following anti-static precautions are strictly adhered to.
Wear an anti-static wristband: - Wearing a simple anti-static wristband can
WAFER-LX3 3.5" Motherboard
help to prevent ESD from damaging the board.
Self-grounding:- Before handling the board touch any grounded conducting
material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.
Use an anti-static pad: When configuring the WA FER-LX3, place it on an
antic-static pad. This reduces the possibility of ESD damaging the
WAFER-LX3.
Only handle the edges of the PCB:-: When handling the PCB, hold the PCB
by the edges.

WAFER-LX3 3.5" Motherboard
5.2 Installation Considerations
NOTE:
The following installation notices and installation considerations should
be read and understood before the WAFER-LX3 is installed. All
installation notices pertaining to the installation of the WAFER-LX3
should be strictly adhered to. Failing to adhere to these precautions
may lead to severe damage of the WAFER-LX3 and injury to the
person installing the motherboard.
5.2.1 Installation Notices
WARNING:
The installation instructions described in this manual should be
carefully followed in order to prevent damage to the WAFER-LX3,
WAFER-LX3 components and injury to the user.
Before and during the installation please DO the following:
Read the user manual:
o The user manual provides a complete description of the WAFER-LX3
installation instructions and configuration options.
Wear an electrostatic discharge cuff (ESD):
o Electronic components are easily damaged by ESD. Wearing an ESD cuff
removes ESD from the body and helps prevent ESD damage.
Place the WAFER-LX3 on an antistatic pad:
o When installing or configuring the motherboard, place it on an antistatic
pad. This helps to prevent potential ESD damage.
Turn all power to the WAFER-LX3 off:
o When working with the WAFER-LX3, make sure that it is disconnected
from all power supplies and that no electricity is being fed into the system.
Page 59
Page 78
Before and during the installation of the WAFER-LX3 DO NOT:
Remove any of the stickers on the PCB board. These stickers are required for
warranty validation.
Use the product before verifying all the cables and power connectors are
properly connected.
Allow screws to come in contact with the PCB circuit, connector pins, or its
components.
5.2.2 Installation Checklist
The following checklist is provided to ensure the WAFER-LX3 is properly installed.

5.3 Unpacking
5.3.1 Unpacking Precautions
When the WAFER-LX3 is unpacked, please do the following:
Follow the anti-static precautions outlined in Section
Make sure the packing box is facing upwards so the WAFER-LX3 does not fall
out of the box.
Make sure all the packing list parts are present
NOTE:
If any packing list components are missing, please do not proceed with
the installation. Contact the IEI reseller or vendor you purchased the
WAFER-LX3 from or contact an IEI sales representative directly. To
contact an IEI sales representative, please send an email to
sales@iei.com.tw.
5.3.2 CF Card Installation
NOTE:
5.1.
The WAFER-LX3 can support both CF Type I cards and CF Type II
cards. For the complete specifications of the supported CF cards
please refer to Chapter 2.
To install the a CF card (Type 1 or Type 2) onto the WAFER-LX3, please follow the steps
below:
Step 1: Locate the CF card socket. Place the WAFER-LX3 on an anti-static pad with
the solder side facing up. Locate the CF card.
Step 2: Align the CF card. Make sure the CF card is properly aligned with the CF
socket.
Page 61
Page 80
Step 3: Insert the CF card. Gently insert the CF card into the socket making sure the
WAFER-LX3 3.5" Motherboard
socket pins are properly inserted into the socket. See

5.4 Jumper Settings
NOTE:
A jumper is a metal bridge that is
used to close an electrical circuit. It
consists of two metal pins and a small
metal clip (often protected by a plastic
cover) that slides over the pins to
connect them. To CLOSE/SHORT a
jumper means connecting the pins of
the jumper with the plastic clip and to
OPEN a jumper means removing the plastic clip from a jumper.
Before the WAFER-LX3 is installed in the system, the jumpers must be set in accordance
with the desired configuration. The jumpers on the WAFER-LX3 are listed in

5.5 Chassis Installation
5.5.1 Airflow
WARNING:
Airflow is critical to the cooling of the CPU and other onboard
components. The chassis in which the WAFER-LX3 must have air
vents to allow cool air to move into the system and hot air to move out.
The WAFER-LX3 must be installed in a chassis with ventilation holes on the sides
allowing airflow to travel through the heat sink surface. In a system with an individual
power supply unit, the cooling fan of a power supply can also help generate airflow
Page 70
through the board surface.
