1.7 Safety Precautions
1.8 System Memory
The PCE-7214 has four sockets for 240-pin dual inline memory modules (DIMMs) in
two separated memory channels. It can operate with single channel or dual channel
modules. We recommend using dual channel mode to provide optimized perfor-
mance. All these sockets use ECC registered DDR2-533/667 SDRAM. The maxi-
mum memory size is up to 32 GB.
1.9 Memory Installation Procedures
To install DIMMs, first make sure the two handles of the DIMM socket are in the
“open” position. i.e. The handles lean outward. Slowly slide the DIMM module along
the plastic guides on both ends of the socket. Then press the DIMM module right
down into the socket, until you hear a click. This is when the two handles have auto-
matically locked the memory module into the correct position of the DIMM socket. To
remove the memory module, just push both handles outward, and the memory mod-
ule will be ejected by the mechanism in the socket.
Warning! Always completely disconnect the power cord from your chassis when-
ever you work with the hardware. Do not make connections while the
power is on. Sensitive electronic components can be damaged by sud-
den power surges. Only experienced electronics personnel should open
the PC chassis.
Caution! Always ground yourself to remove any static charge before touching the
single board computer. Modern electronic devices are very sensitive to
static electric discharges. As a safety precaution, use a grounding wrist
strap at all times. Place all electronic components on a static-dissipative
surface or in a static-shielded bag when they are not in the chassis.
Caution! The computer is provided with a battery-powered Real-time Clock cir-
cuit. There is a danger of explosion if battery is incorrectly replaced.
Replace only with same or equivalent type recommended by the manu-
facturer. Discard used batteries according to manufacturer's instruc-
tions.
Note! Before install your PCE-7214 into a chassis, make sure that all compo-
nents on both sides of the CPU card do not touch any metal parts, espe-
cially the chassis wall and add-on card at the adjacent slot.
