2.9 Onboard Headers and Connectors

Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these headers and connectors. Placing jumper caps over the headers and connectors will cause permanent damage of the motherboard!

Serial ATA2 Connectors

(SATA_1: see p.11, No. 12)

(SATA_2: see p.11, No. 11)

(SATA_3: see p.11, No. 7)

(SATA_4: see p.11, No. 10)

(SATA_5: see p.11, No. 8)

(SATA_6: see p.11, No. 9)

These six Serial ATA2

(SATA2) connectors support

SATA data cables for internal storage devices. The current

SATA2 interface allows up to

3.0 Gb/s data transfer rate.

Either end of the SATA data cable can be connected to the

SATA / SATAII hard disk or the

SATAII connector on this motherboard.

This is an interface for print port cable that allows convenient connection of printer devices.

USB 2.0 Headers

(9-pin USB6_7)

(see p.11 No. 21)

(9-pin USB8_9)

(see p.11 No. 23)

Besides six default USB 2.0

ports on the I/O panel, there are three USB 2.0 headers on this motherboard. Each USB 2.0

header can support two USB

2.0 ports.

1. High Definition Audio supports Jack Sensing, but the panel wire on

the chassis must support HDA to function correctly. Please follow the

instruction in our manual and chassis manual to install your system.

2. If you use AC’97 audio panel, please install it to the front panel audio

header as below:

A. Connect Mic_IN (MIC) to MIC2_L.

B. Connect Audio_R (RIN) to OUT2_R and Audio_L (LIN) to OUT2_L.

C. Connect Ground (GND) to Ground (GND).

D. MIC_RET and OUT_RET are for HD audio panel only. You don’t

need to connect them for AC’97 audio panel.

System Panel Header

(9-pin PANEL1)

(see p.11 No. 17)

This header accommodates several system front panel functions.

Connect the power switch, reset switch and system status indicator on the chassis to this header according to the pin assignments below.

Note the positive and negative pins before connecting the cables.

PWRBTN (Power Switch):

Connect to the power switch on the chassis front panel. You may configure the way to turn off your system using the power switch.

RESET (Reset Switch):

Connect to the reset switch on the chassis front panel. Press the reset switch to restart the computer if the computer freezes and fails to perform a normal restart.

PLED (System Power LED):

Connect to the power status indicator on the chassis front panel. The

LED is on when the system is operating. The LED keeps blinking when the sys-tem is in S1 sleep state. The LED is off when the system is in S3/S4 sleep state or powered off (S5).

HDLED (Hard Drive Activity LED):

Connect to the hard drive activity LED on the chassis front panel. The

LED is on when the hard drive is reading or writing data.

The front panel design may differ by chassis. A front panel module mainly consists of power switch, reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your chassis front panel module to this header, make sure the wire assignments and the pin assign-ments are matched correctly.

Though this motherboard provides 4-Pin CPU fan (Quiet Fan) support, the 3-Pin

CPU fan still can work successfully even without the fan speed control function.

If you plan to connect the 3-Pin CPU fan to the CPU fan connector on this

motherboard, please connect it to Pin 1-3.
