3.1 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the installation of the
WAFER-LX2 may result in permanent damage to the WAFER-LX2 and
severe injury to the user.

Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the WAFER-LX2. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the WAFER-LX2, 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

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 WAFER-LX2, place it on an

antic-static pad. This reduces the possibility of ESD damaging the
WAFER-LX2.

 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-LX2 is unpacked, please do the following:

 Follow the anti-static precautions outlined in Section 3.1.
 Make sure the packing box is facing upward s so the W A FER-LX2 does not fall

out of the box.

 Make sure all the components shown in Section 3.3 are present.

3.3 Unpacking Checklist

NOTE:

If some of the components listed in the checklist below are missing,
please do not proceed with the installation. Contact the IEI reseller or

5.1 Anti-static Precautions

WARNING:

Failure to take ESD precautions during the installation of the
WAFER-LX2 may result in permanent damage to the WAFER-LX2 and
severe injury to the user.

Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the WAFER-LX2. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the WAFER-LX2, or any other electrical component is handled, the
following anti-static precautions are strictly adhered to.

WAFER-LX2 3.5” Embedded SBC

 Wear an anti-static wristband: - Wearing a simple anti-static wristband can

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 WAFER-LX2, place it on an

antic-static pad. This reduces the possibility of ESD damaging the
WAFER-LX2.

 Only handle the edges of the PCB:-: When handling the PCB, hold the PCB

by the edges.

Page 56

WAFER-LX2 3.5” Embedded SBC

5.2 Installation Considerations

NOTE:

The following installation notices and installation considerations should
be read and understood before the WAFER-LX2 is installed. All
installation notices pertaining to the installation of the WAFER-LX2
should be strictly adhered to. Failing to adhere to these precautions
may lead to severe damage of the WAFER-LX2 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-LX2, WAFER-LX2
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-LX2

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-LX2 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-LX2 off:

Page 57

o When working with the WAFER-LX2, make sure that it is disconnected

from all power supplies and that no electricity is being fed into the system.

Before and during the installation of the WAFER-LX2 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-LX2 is properly installed.

WAFER-LX2 3.5” Embedded SBC

 All the items in the packing list are present (see Chapter 4)
 A compatible memory module is properly inserted into the slot (see Chapter

2)

 The CF Type I or CF Type II card is pro perly installed into the CF socket
 The jumpers have been properly configured
 The WAFER-LX2 is installed into a chassis with adequate ventilation
 The correct power supply is being used
 The following devices are properly connected

o Audio kit
o Power supply
o Serial port cables

 The following external peripheral devices are properly connected to the

chassis:

o VGA screen
o RS-232 serial communications device
o USB devices

5.3 SODIMM Installation and CF Card Installation

5.3.1 SODIMM Installation

WARNING:

Using an incorrectly specified SODIMM may cause permanent damage
to the WAFER-LX2. Please make sure the purchased SODIMM
complies with the memory specifications of the WAFER-LX2. SODIMM
specifications compliant with the WAFER-LX2 are listed in Chapter 2.

To install a SODIMM into a SODIMM socket, please follow the steps below and refer
Figure 5-1.

Figure 5-1: SODIMM Installation

Step 1: Locate the SODIMM socket. Place the WAFER-LX2 on an anti-static pad with

the solder side facing up.

Step 2: Align the SODIMM with the socket. The SODIMM must be oriented in such a

way that the notch in the middle of the SODIMM must be aligned with the plastic
bridge in the socket.

Page 59

Step 3: Insert the SODIMM. Push the SODIMM chip into the socket at an angle. (See

Figure 5-1)

Step 4: Open the SODIMM socket arms. Gently pull the arms of the SODIMM socket

WAFER-LX2 3.5” Embedded SBC

out and push the rear of the SODIMM down. (See

Step 5: Secure the SODIMM. Release the arms on the SODIMM socket. They clip into

place and secure the SODIMM in the socket.Step 0:

Figure 5-1)

5.3.2 CF Card Installation

Note:

The WAFER-LX2 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-LX2, please follow the steps
below:

Page 60

Step 1: Locate the CF card socket. Place the WAFER-LX2 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.

Step 3: Insert the CF card. Gently insert the CF card into the socket making sure the

socket pins are properly inserted into the socket. See

Figure 5-2.

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

jumper.

Before the WAFER-LX2 is installed in the system, the jumpers must be set in accordance
with the desired configuration. The jumpers on the WAFER-LX2 are listed in

Table 5-1.

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-LX2 must have air
vents to allow cool air to move into the system and hot air to move out.

The WAFER-LX2 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
through the board surface.
