ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

2.3 Installing Thermal Solution
For thermal dissipation, a thermal solution enables the CEM310/311’s components to dissipate
heat efficiently. All heat generating components are thermally conducted to the heatspreader in
order to avoid hot spots. Below images illustrate how to install the thermal solution on
CEM310/311.
1. There is a protective plastic covering on the thermal pads. This must be removed before
the heatspreader can be mounted.
2. Each thermal solution is designed for a specific CEM module. The thermal pads on the
heatspreader are designed to make contact with the necessary components on the CEM
module. When mounting the heatspreader you must make sure that the thermal pads on
the heatspreader make complete contact (no space between thermal pad and
component) with the corresponding components on the CEM module. This is especially
critical for CEM modules that have higher CPU speeds (for example 1.46GHz or more) to
ensure that the heatspreader acts as a proper thermal interface for cooling solutions.
3. Before installing the heatspreader to the CPU module, please apply thermal grease on
the CPU die. This CPU module has four assembly holes for installing heatspreader plate.
Use the four screws to secure the heatspreader plate to the CEM310/311. Be careful not
to over-tighten the screws. Then, apply thermal grease at the bottom of heatsink and
secure the heatsink on the heatspreader by another four screws.

you can find a summary table of switch and onboard default setting.
Note
Once the default switch setting needs to be changed, please do it under power-off
condition.
