2.7.1 System Monitoring
The IEM-LX-800 is capable of self-monitoring various aspects of its operating status
including:
CPU, chipset, and battery voltage, +3.3V, +5V, and +12V
RPM of cooling fans
CPU and board temperatures (by the corresponding embedded sensors)
2.7.2 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the IEM-LX-800 are listed below.
Minimum Operating Temperature: 0ºC (32°F)
Maximum Operating Temperature: 60°C (140°F)
A cooling fan and heat sink must be installed on the CPU. Thermal paste must be
smeared on the lower side of the heat sink before it is mounted on the CPU. Heat sinks
are also mounted on the Northbridge and Southbridge chipsets to ensure the operating
temperature of these chips remain low.

3.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the installation of the
IEM-LX-800 may result in permanent damage to the IEM-LX-800 and
severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the IEM-LX-800. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the IEM-LX-800, or any other electrical component is handled, the
following anti-static precautions are strictly adhered to.
IEM-LX-800 ETX CPU Module
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 IEM-LX-800, place it on an
antic-static pad. This reduces the possibility of ESD damaging the
IEM-LX-800.
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 IEM-LX-800 is unpacked, please do the following:
Follow the anti-static precautions outlined in Section 3.1.
Make sure the packing box is facing upwards so the IEM-LX-800 does not fall
out of the box.
Make sure all the components shown in Section 3.3 are present.

5.1 Installation Considerations
NOTE:
The following installation notices and installation considerations should be
read and understood before the CPU module is installed. All installation
notices pertaining to the installation of the CPU module should be strictly
adhered to. Failing to adhere to these precautions may lead to severe
damage of the CPU module and injury to the person installing the CPU
module.
5.1.1 Installation Notices
IEM-LX-800 ETX CPU Module
Before and during the installation of the IEM-LX, please do the following:
Read the user manual
o
The user manual provides a complete description of the IEM-LX,
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 CPU module on an antistatic pad
o
When installing or configuring the CPU module, place it on an antistatic
pad. This helps to prevent potential ESD damage.
Turn off all power to the IEM-LX
o
When working with the CPU module, 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 IEM-LX 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
Page 36
IEM
-LX-
properly connected.
allow screws to come in contact with the PCB circuit, connector pins, or its
components.
5.2 Unpacking
NOTE:
If any of the items listed below are missing when the IEM-LX is unpacked,
do not proceed with the installation and contact the IEM-LX reseller or
vendor.
5.2.1 Unpacking Precautions
Before installing the IEM-LX, unpack the CPU module. Some components on IEM-LX are
very sensitive to static electricity and can be damaged by a sudden rush of power. To
protect it from being damaged, follow these precautions:
The user should ground them self to remove any static charge before
touching the IEM-LX. To do so wear a grounded wrist strap at all times or
frequently touch any conducting materials that is connected to the ground.
Handle the IEM-LX by its edges. Do not touch the IC chips, leads or circuitry if
not necessary.
Do not place a PCB on top of an anti-static bag. Only the inside of the bag is safe from
static discharge.
5.2.2 Checklist
When unpacking the IEM-LX, please make sure that the package contains the following
items.
1 x IEM-LX embedded module
1 x Mini jumper pack
Page 37
Please note that the installation instructions described in this manual should
static
1 x Utility CD
1 x QIG
If one or more of these items are missing, please contact the reseller or vendor the
IEM-LX was purchased from and do not proceed any further with the installation.

5.3 IEM-LX Embedded Module Installation
WARNING!
Never run the embedded module without an appropriate heat sink.
WARNING!
be carefully followed in order to avoid damage to the CPU module
components and injury to the user.
WARNING!
When installing electronic components onto the embedded module or
installing the embedded module onto the baseboard, always take anti-
precautions in order to prevent ESD damage to the CPU module and other
electronic components like the CPU and SO-DIMM module.
The following components must be installed onto the CPU module or connected to the
CPU module during the installation process.

5.3.1 SO-DIMM Installation
WARNING:
Using incorrectly specified SO-DIMM may cause permanently damage
the IEM-LX-800. Please make sure the purchased SO-DIMM complies
with the memory specifications of the IEM-LX-800. SO-DIMM
specifications compliant with the IEM-LX-800 are listed in Chapter 2.
To install a SO-DIMM into a SO-DIMM socket, please follow the steps below and refer to
Figure 5-1.
Figure 5-1: SO-DIMM Installation
Step 1: Locate the SO-DIMM socket. Place the IEM-LX-800 on an anti-static pad.
Step 2: Align the SO-DIMM with the socket. The SO-DIMM must be oriented in such a
way that the notch in the middle of the SO-DIMM must be aligned with the
plastic bridge in the socket.
Step 3: Insert the SO-DIMM. Push the SO-DIMM chip into the socket at an angle. (See
Figure 5-1)
Step 4: Open the SO-DIMM socket arms. Gently pull the arms of the SO-DIMM socket
Page 39
out and push the rear of the SO-DIMM down. (See Figure 5-1)
Step 5: Secure the SO-DIMM. Release the arms on the SO-DIMM socket. They clip into
place and secure the SO-DIMM in the socket.Step 0:
5.3.2 Mounting the IEM-LX Embedded Module
The IEM-LX embedded module has four standard ETX connectors on the reverse side.
Align these ETX connectors (ETX-X1, ETX-X2, ETX-X3 and ETX-X4) with the
corresponding connectors on a compatible baseboard. Gently push the embedded
module down to ensure the connectors are properly connected.
Baseboard can be designed by the end user, customized by IEI, or purchased from IEI.
For more information visit the IEI webstie (www.ieiworld.com) or contact an IEI sales
representative.

6.1 Introduction
A licensed copy of Phoenix Award BIOS is preprogrammed into the ROM BIOS. The BIOS
setup program allows users to modify the basic system configuration. This chapter
describes how to access the BIOS setup program and the configuration options that may
be changed.
6.1.1 Starting Setup
The Phoenix Award BIOS is activated when the computer is turned on. The setup program
can be activated in one of two ways.
