o Maximum Operating Temperature: 60°C
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 NOVA-LX
may result in permanent damage to the NOVA-LX and severe injury to
the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the NOVA-LX. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the NOVA-LX, 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 NOVA-LX, place it on an
antic-static pad. This reduces the possibility of ESD damaging the NOVA-LX.
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 NOVA-LX 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 NOVA-LX 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
vendor you purchased the NOVA-LX from or contact an IEI sales
representative directly. To contact an IEI sales representative, please

5.1 Anti-static Precautions
WARNING:
Failure to take ESD precautions during the installation of the NOVA-LX
may result in permanent damage to the NOVA-LX and severe injury to
the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the NOVA-LX. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the NOVA-LX, or any other electrical component is handled, the
following anti-static precautions are strictly adhered to.
NOVA-LX 5.25” Motherboard
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 NOVA-LX, place it on an
antic-static pad. This reduces the possibility of ESD damaging the NOVA-LX.
Only handle the edges of the PCB:-: When handling the PCB, hold the PCB
by the edges.

5.2 Installation Considerations
NOTE:
The following installation notices and installation considerations should
be read and understood before the NOVA-LX is installed. All installation
notices pertaining to the installation of the NOVA-LX should be strictly
adhered to. Failing to adhere to these precautions may lead to severe
damage of the NOVA-LX 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 NOVA-LX, NOVA-LX
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 NOVA-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 NOVA-LX 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 NOVA-LX off:
Page 71
Page 92
o When working with the NOVA-LX, 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 NOVA-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
properly connected.
Allow screws to come in contact with the PCB circuit, connector pins, or its
components.

5.3 Unpacking
5.3.1 Unpacking Precautions
When the NOVA-LX is unpacked, please do the following:
Follow the anti-static precautions outlined in Section 5.1.
Make sure the packing box is facing upwards so the NOVA-LX does not fall
out of the box.
Make sure all the components in the checklist shown in Chapter 3 are
present.
NOTE:
If some of the components listed in the checklist in Chapter 3 are
missing, please do not proceed with the installation. Contact the IEI
reseller or vendor you purchased the NOVA-LX from or contact an IEI
sales representative directly. To contact an IEI sales representative,
please send an email to

5.4 CF Card Installation
NOTE:
The NOVA-LX 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 NOVA-LX, please follow the steps
below:
Step 1: Locate the CF card socket. Place the NOVA-LX on an anti-static pad with the
NOVA-LX 5.25” Motherboard
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 5-1. Step 0:

5.5 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 NOVA-LX is installed in the system, the jumpers must be set in accordance
with the desired configuration. The jumpers on the NOVA-LX are listed in
Table 5-1.
