Installing the Motherboard
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 they came in
• Hold all circuit boards by the edges. Do not bend circuit boards
Choosing a Computer Case
There are many types of computer cases on the market. The motherboard complies
with the specifications for the ATX system case. Firstly, some features on the
motherboard are implemented by cabling connectors on the motherboard to indicators and switches on the system case. Make sure that your case supports all the
features required. Secondly, this motherboard supports one floppy diskette drive and
two enhanced IDE drives. Make sure that your case has sufficient power and space for
all drives that you intend to install.
Most cases have a choice of I/O templates in the rear panel. Make sure that the I/O
template in the case matches the I/O ports installed on the rear edge of the
motherboard.
This motherboard carries an ATX form factor of 305 X 220 mm. Choose a case that
accommodates this form factor.
7
Installing the Motherboard in a Case
Refer to the following illustration and instructions for installing the motherboard in
a case.
Most system cases have mounting brackets installed in the case, which correspond
the holes in the motherboard. Place the motherboard over the mounting brackets
and secure the motherboard onto the mounting brackets with screws.
Ensure that your case has an I/O template that supports the I/O ports and expansion
slots on your motherboard.
Installing the Motherboard

Do not over-tighten the screws as this can stress the motherboard.
Checking Jumper Settings
This section explains how to set jumpers for correct configuration of the motherboard.
Setting Jumpers
Use the motherboard jumpers to set system configuration options. Jumpers with
more than one pin are numbered. When setting the jumpers, ensure that the jumper
caps are placed on the correct pins.
The illustrations show a 2-pin jumper. When
the jumper cap is placed on both pins, the
jumper is SHORT. If you remove the jumper
cap, or place the jumper cap on just one pin,
the jumper is OPEN.
This illustration shows a 3-pin jumper. Pins
1 and 2 are SHORT.
SHORT OPEN

The following illustration shows the location of the motherboard jumpers. Pin 1 is
labeled.

Jumper Type Description

USB_PWR2
USB_PWR3
1. To avoid the system unstability after clearing CMOS, we recommend
users to enter the main BIOS setting page to “Load Optimal Defaults”
and then “Save Changes and Exit”.
2. Make sure the power supply provides enough 5VSB voltage before
selecting the 5VSB function.
3. It is required that users place the USB_PWR1 & USB_PWR2 &
USB_PWR3 cap onto 2-3 pin rather than 1-2 pin as default if you want
to wake up the computer by USB/PS2 KB/Mouse.

Connecting Case Components
After you have installed the motherboard into a case, you can begin connecting the
motherboard components. Refer to the following:
1 Connect the CPU cooling fan cable to CPU_FAN.
2 Connect the standard power supply connector to ATX_POWER.
3 Connect the case speaker cable to SPK.
4 Connect the case switches and indicator LEDs to the F_PANEL.
5 Connect the system cooling fan connector to SYS_FAN.
6 Connect the auxiliary case power supply connector to ATX12V1.
Connecting 24-pin power cable
Users please note that the 24-pin power cable can be connected to the
ATX_POWER connector.
24-pin power cable
With ATX v2.x power supply, users please
note that when installing 24-pin power
cable, the latches of power cable and the
ATX_POWER match perfectly.

Front Panel Header
The front panel header (F_PANEL) provides a standard set of switch and LED
headers commonly found on ATX or Micro ATX cases. Refer to the table below for
information:
Pin Signal Function Pin Signal Function

3 HD_LED_N Hard disk LED (-)
5 RST_SW_N Reset Switch (-)
7 RST_SW_P Reset Switch (+)
9 RSVD Reserved
* MSG LED (dual color or single color)
Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indication
that data is being read from or written to the hard drive. For the LED to function
properly, an IDE drive should be connected to the onboard IDE interface. The LED
will also show activity for devices connected to the SCSI (hard drive activity LED)
connector.

6 PWR_SW_P Power Switch (+)

10 Key No pin
Power/Sleep/Message waiting LED
Connecting pins 2 and 4 to a single or dual-color, front panel mounted LED provides
power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pin 5 and 7 to a momentarycontact switch that is normally open. When the switch is closed, the board resets and
runs POST.
Power Switch
Supporting the power on/off function requires connecting pins 6 and 8 to a momentary-contact switch that is normally open. The switch should maintain contact for at
least 50 ms to signal the power supply to switch on or off. The time requirement is
due to internal de-bounce circuitry. After receiving a power on/off signal, at least two
seconds elapses before the power supply recognizes another on/off signal.
