Quick Start
The basic procedures required to power on CEM312/313:
(1). Require DC +12V power at minimum 2.67A. Make sure the power is
OFF before connecting the CEM312/313.
(2). Check to ensure the onboard switch SW1-1 is set to default (OFF
position).
(3). Firmly install DDR3L module in SODIMM1/SODIMM2 until fully seated.
For single memory channel configuration, install memory module in
channel 0 (SODIMM2) DDR3L SO-DIMM socket. For dual memory
channel configuration, install memory modules of the same size, chip
width, density and rank in both channel 0 (SODIMM1) and channel 1
(SODIMM2) DDR3L SO-DIMM sockets.
(4). Attach heatsink to the CEM312/313, refer to section Installing
Thermal Solution.
(5). Install the CEM312/313 onto COM Express
TM
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.
(9). Press power button on the baseboard to start CEM312/313.

Installing Thermal Solution
For thermal dissipation, a thermal solution enables the CEM312/313’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 CEM312/313.
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
1.46GHz 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 four assembly holes for
installing heatsink plate. Use the four screws to secure the heatsink
plate to the CEM312/313. Be careful not to over-tighten the screws.

Note: When installing CEM312/313 on CEB94006 or CEB94011, please
add stand-off and secure with nut. Then, use the screws to
secure heatsink plate to CEM312/313 as indicated in images
below.
