Chapter 2 Hardware Setup
2.1 Choosing a Computer Chassis
• Choose a chassis big enough to install this mainboard.
• As some features for this mainboard are implemented by cabling connectors on the
mainboard to indicators and switches or buttons on the chassis, make sure your chassis
supports all the features required.
• If there is possibility of adopting some more hard drives, make sure your chassis has
sufcient power and space for them.
• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O
shield of the chassis matches the I/O port conguration of this mainboard. You can nd
an I/O shield specically designed for this mainboard in its package.
2.2 Installing the Mainboard
Most computer chassis have a base with many mounting holes to allow the mainboard to
be securely attached, and at the same time, prevent the system from short circuits. There
are two ways to attach the mainboard to the
chassis base: (1) with studs, or (2) with spacers.
Basically, the best way to attach the board is with
studs. Only if you are unable to do this should you
attach the board with spacers. Line up the holes on
the board with the mounting holes on the chassis.
If the holes line up and there are screw holes, you
can attach the board with studs. If the holes line
up and there are only slots, you can only attach with
spacers. Take the tip of the spacers and insert them
into the slots. After doing this to all the slots, you can slide the board into position aligned
with slots. After the board has been positioned, check to make sure everything is OK before
putting the chassis back on.
To install this mainboard:
1. Locate all the screw holes on the mainboard and the chassis base.
2. Place all the studs or spacers needed on the chassis base and have them tightened.
3. Face the mainboard’s I/O ports toward the chassis’s rear panel.
4. Line up all the mainboard’s screw holes with those studs or spacers on the chassis.
5. Install the mainboard with screws and have them tightened.
The mainboard and its component layouts illustrated in this chapter were
based mainly on model “JW-N7AS-HD”, unless specically stated.
Always power off the computer and unplug the AC power cord before adding or removing
any peripheral or component. Failing to do so may cause severe damage to your
mainboard and/or peripherals. Plug in the AC power cord only after you have carefully
checked everything.
To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they are
already fastened on the chassis base and are without mounting-holes on the mainboard to
align with.

2.3 Installation of the CPU and CPU Cooler
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the mainboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction
of the CPU.
3. Please add an even layer of heat sink paste between the CPU and CPU cooler.
4. Please make sure the CPU cooler is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specications. It is not
recommended that the system bus frequency be set beyond hardware specications since
it does not meet the required standards for the peripherals. If you wish to set the frequen-
cy beyond the proper specications, please do so according to your hardware
specications including the CPU, graphics card, memory, hard drive, etc.
2.3.1 Installation of the CPU
1. Open the socket lever by
pushing the lever down and
away from the socket (see
Figure 1, 1 and 2).
2. Lift the load plate. Do not
touch the socket contacts
(see Figure 2, 3 and 4)
3 . R e m o ve t h e p l a s t i c
protective socket cover
from the load plate (see
Figure 3, 5). Do not discard
the protective socket cover.
Always replace the socket
cover if the processor is
removed from the socket.
4. Remove the processor
f r o m t h e p r o t e c t i v e
processor cover. Hold the
processor only at the edges,
being careful not to touch
the bottom of the processor
(see Figure 4). Do not
d i s c a r d t h e p r o t e c t i v e
processor cover. Always
replace the processor
back to the package if the
processor is removed from
the socket.
5. Hold the processor with
y o u r t h u m b a n d i n d e x
ngers oriented as shown in
Figure 5. Make sure ngers
align to the socket cutouts
(see Figure 5, 6). Align
notches (see Figure 5, 7)
with the socket see (Figure
5, 8). Lower the processor
straight down without tilting
or sliding the processor in
the socket.
6. Pressing down on the
load plate (Figure 6, 9)
c l o s e a n d e n g a g e t h e
socket lever (Figure 6, 10).

2.3.2 Installation of the CPU Cooler
For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.
2.4 Installation of Memory Modules
This mainboard provides four 240-pin DDRII (Double Data Rate) DIMM slots, and supports
Dual Channel Memory Technology. For dual channel conguration, you always need to install
two identical (the same brand, speed, size and chip-type) memory modules in the DDRII
DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single
channel mode.
To reach the performance of Dual Channel DDR2, the following rules must be obeyed:
For 2-DIMM dual-channel installation:
Populate DIMM modules of the same type and size on slots [DIMM1]+[DIMM3]
Populate DIMM modules of the same type and size on slots [DIMM2]+[DIMM4]
To install system memory:
1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2. Locate the DIMM slot on the board.
3. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4. Align the notch key on the module with
the rib on the slot.
5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra
force as the DIMM module only ts in one direction.
6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static
electricity by touching a grounded metal object briey.
