Quick Start
The basic procedures required to power on CEM520:
(1). Make sure the power is OFF before connecting the CEM520.
(2). Check to ensure the onboard switch SW1-1 and SW1-2 are set to
default (OFF position).
(3). Firmly install DDR4 SO-DIMM in DIMM1/DIMM2 until fully seated. For
single memory channel configuration, install memory module in
channel 0 (DIMM1) DDR4 SO-DIMM socket. For dual memory
channel configuration, install memory modules of the same size, chip
width, density and rank in both channel 0 (DIMM1) and channel 1
(DIMM2) DDR4 SO-DIMM sockets.
(4). Attach heatsink to the CEM520, refer to section Installing Thermal
Solution.
(5). Install the CEM520 onto COM Express
TM
baseboard, for example,
CEB94011 baseboard.
(6). Properly install all necessary peripheral devices such as hard disk,
display, keyboard and etc. to the baseboard.
(7). Firmly attach power supply to the baseboard power connector.
(8). Turn on the system power.
(9). Press power button on the baseboard to start CEM520.

Installing Thermal Solution
For thermal dissipation, a thermal solution enables the CEM520’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 CEM520.
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
1.0GHz 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 CEM520. Be careful not to over-tighten the screws.
