Quick Start
The basic procedures required to power on CEM500:
(1). Make sure the power is OFF before connecting the CEM500.
(2). Check to ensure the onboard switch SW1-1 is 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.
Note: It must be DDR4 memory module.
(4). Attach heatsink to the CEM500, refer to section Installing Heatsink.
(5). Install the CEM500 onto COM ExpressTM baseboard, for example,
CEB94006 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’s power connector.
(8). Turn on the system power.

Installing Heatsink
For thermal dissipation, a heatsink enables the CEM500’s components to
dissipate heat efficiently. All heat generating components are thermally
conducted to the heatsink in order to avoid hot spots. Below images
illustrate how to install the heat spreader.
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. This CPU module has six assembly holes for installing heat spreader
plate. Use the six screws to secure the heat spreader plate to the
CEM500. Be careful not to over-tighten the screws.
