9 / 31
Chapter2. Installation
This is a Mini-ITX form factor (6.7" x 6.7", 17.0 x 17.0 cm) motherboard. Before you install the motherboard, study the configuration of
your chassis to ensure that the motherboard fits into it.
Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so may cause physical
injuries to you and damages to motherboard components.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-Installation Precautions
Take note of the following precautions before you install motherboard components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity, NEVER place your motherboard directly on the carpet
or the like. Also remember to use a grounded wrist strap or touch a safety grounded object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that comes with the component.
Before you install or remove any component, ensure that the power is switched off or the power cord is detached from
the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,and/or components.
2.3 Installation of Memory Modules (SO-DIMM)
ITX-D255R motherboard provides two 204-pin DDR3 (Double Data Rate 3) SO-DIMM slots.
1. It is not allowed to install a DDR or DDR2 memory module into a DDR3 slot; otherwise, this motherboard and SO-DIMM
may be damaged.
2. Please install the memory module from DDR3_A2 slot for the first priority.
2.3.1 Installation a SO-DIMM
Please make sure to disconnect the power supply before adding or removing SO-DIMMs or the system components.
Step#1] Unlock a SO-DIMM slot by pressing the retaining clips outward.
Step#2] Align a SO-DIMM on the slot such that the notch on the SO-DIMM matches the break on the slot.
The SO-DIMM only fits in one correct orientation. It will cause perma- nent damage to the motherboard and the SO-DIMM
if you force the SO- DIMM into the slot in the incorrect orientation.
Step#3] Firmly insert the SO-DIMM into the slot until the retaining clips at both ends fully snap back in place and the SO-DIMM
is properly seated.
