ESD Precautions

Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:

 Do not remove boards or integrated circuits from their anti-static packaging until you are

ready to install them.

 Before holding the board or integrated circuit, touch an unpainted portion of the system

unit chassis for a few seconds. It discharges static electricity from your body.

 Wear a wrist-grounding strap, available from most electronic component stores, when

handling boards and components.

External Speaker

Pin 1(-) and 2(+) connect the case-mounted speaker unit or internal buzzer cable.

Power Status

Pin 4 and pin 3 are for power status button; letting user know the power status of this
board.

Power LED

Pin 6 connects anode (+) of LED and pin 5 connects cathode (-) of LED. The power LED
lights up when the system is powered on.

Power On/Off Button

Pin 8 and 7 connect the power button on front panel to CPU board, which allows users to
turn on or off power supply.

System Reset Switch

Pin 10 and 9 connect the case-mounted reset switch that reboots your computer without
turning off the power switch. It is a better way to reboot your system for a longer life of
system power supply.

HDD Activity LED
This connection is linked to hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. Pin 12 and 11 connect the hard disk drive to the front
panel HDD LED, pin 11 is assigned as cathode(-) and pin 12 is assigned as anode(+).

2.4.4 DC +12V Power Input Connector (CN5/ATX1)

Steady and sufficient power can be supplied to all components on the board by
connecting the power connector. Please make sure all components and devices are
properly installed before connecting the power connector.
