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.

2.3.1 Restore BIOS Optimal Defaults (JP1)
Put jumper clip to pin 3-5 for a few seconds then move it back to pin 1-1. Doing this
procedure can restore BIOS optimal defaults.
2.3.2 Auto Power On (JP1)
If JP1 is enabled for AC power input, the system will be automatically power on without
pressing soft power button. If JP1 is disabled for AC power input, it is necessary to
manually press soft power button to power on the system.

2.4.3 Front Panel Connector (CN3)
Power LED
This 3-pin connector denoted as Pin 1 and Pin 5 connects the system power LED
indicator to such a switch on the case. Pin 1 is assigned as +, and Pin 5 as -. The Power
LED lights up when the system is powered ON. Pin 3 is defined as GND.
External Speaker and Internal Buzzer Connector
Pin 2, 4, 6 and 8 can be connected to the case-mounted speaker unit or internal buzzer.
While connecting the CPU card to an internal buzzer, please short pins 2-4; while
connecting to an external speaker, you need to set pins 2-4 to Open and connect the
speaker cable to pin 8 (+) and pin 2 (-).
ATX Power On/Off Button
This 2-pin connector denoted as Pin 9 and 10 connects the front panel’s ATX power
button to the CPU card, which allows users to control ATX power supply to be power
on/off.
System Reset Switch
Pin 11 and 12 can be connected to the case-mounted reset switch that reboots your
computer instead of turning OFF the power switch. It is a better way to reboot your
system for a longer life of the system’s 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 13 and 14 connect the hard disk drive to the front
panel HDD LED, Pin 13 assigned as -, and Pin 14 as +.
