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.

2.4.13 USB Connectors (CN21, CN22, CN23 and CN25)
The CN21, CN22, CN23 and CN25 are interfaces carrying USB port 4 and 5, USB port 8
and 9, USB port 10 and 11 and USB port 6 and 7, respectively. They are for installing
versatile USB 2.0 compliant peripherals. These connectors are designed with +5V level
standby power which can provide power when system is in suspend mode.
CN21,CN22,CN23,CN25
2.4.14 SMBus Connector (CN24)
This connector is for SMBus interface. The SMBus (System Management Bus) is a
simple bus for the purpose of lightweight communication. Most commonly it is used for
communication with the power source related applications such as on/off instructions.
2.4.15 Serial ATA Connectors (CN26, CN27, CN28, SATA1 and
SATA2)
These Serial Advanced Technology Attachment (Serial ATA or SATA) connectors are for
high-speed SATA interfaces. They are computer bus interfaces for connecting to devices
such as hard disk drives.
This board has three SATA 2.0 ports (CN26, CN27 and CN28) with 3Gb/s performance
and two SATA 3.0 ports (SATA1 and SATA2) with 6Gb/s performance.

2.4.16 ATX Power Connectors (CN29 and ATX2)
Steady and sufficient power can be supplied to all components on the board by
connecting power connector. Please make sure all components and devices are
properly installed before connecting the power connector.
External power supply plug fits into this connector in only one orientation. Properly press
down power supply plug until it completely and firmly fits into this connector. Loose
connection may cause system instability.
The CN29 is a 24-pin ATX power connector. Its pin assignments are given in table below.
The ATX2 is an 8-pin +12V ATX power connector for connecting CPU core voltage.
2.4.17 Internal Power Connector (CN30)
The internal power interface is available through this connector.

2.4.18 CFast™ Socket (CF1)
The board is equipped with a CFastTM socket to support CFastTM card which is based on
the Serial ATA bus. The socket is specially designed to avoid incorrect installation of
CFast
TM
card. When installing or removing CFastTM card, please make sure system
power is off. The CFast
TM
card by default identifies itself as C: or D: drive in your PC
system.
2.4.19 Fan Connectors (FAN1 and FAN2)
Fans are always needed for cooling down CPU and system temperature. The board has
two fan connectors. You can find fan speed on BIOS Setup Utility if CPU fan is installed.
For further information, see BIOS Setup Utility: Advanced\HW Monitor\PC Health Status
(refer to section 5.4).
The FAN1 is a CPU fan interface, see table below.
The FAN2 is a system fan interface, see table below.
