Installing the Motherboard
2-1. Safety Precautions
Follow these safety precautions when installing the motherboard:
•Wear a grounding strap attached to a grounded device to avoid damage
from static electricity.
•Discharge static electricity by touching the metal case of a safely grounded
object before working on the motherboard.
•Leave components in the static-proof bags.
•Always remove the AC power by unplugging the power cord from the power
outlet before installing or removing the motherboard or other hardware
components.
2-2. Installing the motherboard in a Chassis
This motherboard carries a Mini ITX form factor of 170 x 170 mm. Choose a chassis
that accommodates this from factor. Make sure that the I/O template in the chassis
matches the I/O ports installed on the rear edge of the motherboard. Most system
chassis have mounting brackets installed in the chassis, which corresponds to the
holes in the motherboard. Place the motherboard over the mounting brackets and
secure the motherboard onto the mounting brackets with screws.
Chapter 2
Do not over-tighten the screws as this can stress the motherboard.

2-3. Checking Jumper Settings
The following illustration shows the location of the motherboard jumpers. Pin 1 is
labeled.
Chapter 2
To avoid the system instability after clearing CMOS, we recommend users to
enter the main BIOS setting page to “Load Default Settings” and then “Save
and Exit Setup”.

2-4. Installing Hardware
2-4-1. Installing Memory Modules
•This motherboard accommodates two memory modules. It can support
one 204-pin DDR3 1066.
•Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
•You must install one module. Total memory capacity is 8 GB.
•Refer to the following to install the memory modules.
Install the DIMM module into the slot and press it firmly down until it
seats correctly. Check that the cutouts on the DIMM module edge
connector match the notches in the DIMM slot.

2-4-2. Installing Add-on Cards
The slots on this motherboard are designed to hold expansion cards and connect
them to the system bus. Expansion slots are a means of adding or enhancing the
motherboard’s features and capabilities. With these efficient facilities, you can
increase the motherboard’s capabilities by adding hardware that performs tasks
Chapter 2
that are not part of the basic system.
MPE1 SlotsThe mini PCI Express x1 slot is for extending usage. It supports
PCIEX8 Slot
a full-card.
The PCI Express x8 slot is fully compliant to the PCI Express Base
Specification revision 2.0.
Before installing an add-on card, check the documentation for
the card carefully. If the card is not Plug and Play, you may have
to manually configure the card before installation.
10
VX900-I2 USER MANUAL
Follow these instructions to install an add-on card:
1Remove a blanking plate from the system case corresponding to the slot
you are going to use.
2Install the edge connector of the add-on card into the expansion slot.
Ensure that the edge connector is correctly seated in the slot.
3Secure the metal bracket of the card to the system case with a screw.
1. For some add-on cards, for example graphics adapters and network adapters, you have to install drivers and software before you can begin using the
add-on card.
Please refer the following illustrations to install the add-on card:
