2.7 Environmental and Power Specifications
2.7.1 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the WAFER-LX3 are listed below.
WAFER-LX3-800 (board revision 1): Operates in a normal range of ambient
temperatures between 0°C ~ +60°C
WAFER-LX3-800W (board revision 1): Operates in a wide range of
ambient temperatures between -20°C ~ +80°C
WAFER-LX3-800 (board revision 2): Operates in a normal range of ambient
temperatures between 0°C ~ +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.
2.7.2 Power Consumption
Table 2-3 shows the power consumption parameters for the WAFER-LX3 running with an
AMD Geode™ LX 800 CPU with 256 MB of onboard memory.

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.
WAFER-LX3 3.5” 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 WAFER-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 3.1.
Page 38
Make sure the packing box is facing upward s so the W A FER-LX3 does not fall
out of the box.
Make sure all the components shown in Section 3.3 are present.
