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 modules or integrated circuits from their anti-static packaging until you are
ready to install them.
◼Before holding the module 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 modules and components.

2.3 Installing Thermal Solution
For thermal dissipation, a thermal solution enables the CEM530’s components to dissipate heat
efficiently. All heat generating components are thermally conducted to the heatsink in order to
avoid hot spots. Figure below illustrates how to install the thermal solution on CEM530.
1. There is a protective plastic covering on the thermal pads. This must be removed before
the heatsink can be mounted.
2. Each heatsink is designed for a specific CEM module. The thermal pads on the heatsink
are designed to make contact with the necessary components on the CEM module. When
mounting the heatsink you must make sure that the thermal pads on the heatsink 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 1.6GHz or more) to ensure that the heatsink acts as a
proper thermal interface for cooling solutions.
3. Before installing the heatsink to the CPU module, please apply thermal grease on the
CPU die. This CPU module has assembly holes for installing heatsink plate. Use the
appropriate screws to secure the heatsink plate to the CEM530. Be careful not to over-
tighten the screws.

2.4 Switch Settings
Properly configure switch settings on the CEM530 to meet your application purpose. Below you
can find a summary table of all switches and onboard default settings.
Note
Once the default switch setting needs to be changed, please do it under power-off
condition.

SW1-1 OFF, SW1-2 OFF
2.4.1 Auto Power On and Restore BIOS Optimal Defaults (SW1)
If dip1 of SW1 (SW1-1) is set to ON position, the system will be automatically power on
without pressing soft power button. If this switch is set to OFF position, it is necessary to
manually press soft power button to power on the system.
The dip2 of SW1 (SW1-2) is for restoring BIOS default status. Flip SW1-2 to ON position
for a few seconds then flip it back to OFF position. Doing this procedure can restore BIOS
optimal defaults.
