2-7 Connector and Jumper Settings

Connectors are used to link the system board with other parts of the system, including

power supply, keyboard, and the various controllers on the front panel of the system

case.

The power supply connector is the last connection to be made while

installing a motherboard. Before connecting the power supply, please

make sure it is not connected to the power source.

All cables that provided by CHAINTECH come with a security-proof.

CN23 / 22 (ATX Power Supply Connector):

The power cord leading from the system's power supply to the

external power source must be the very last part connected when

assembling a system. The ATX power supply provides a single

20-pin connector interface, which incorporates standard +/-5V,

+/-12V, optional 3.3V and Soft-power signals. The Soft

power signal, a 5V trickle supply is continuously supplied

when AC power is available. When the system is in Soft-Off

mode, this trickle supply maintains the system in its

minimum power state.

The ATX 12V power supply has a new +12V (4-pin) and

+5V / 3.3V (6-pin) auxiliary power connector to enable the delivery of more +12

VDC and + 5/ 3.3V VDC current to the motherboard.

Power-On By Modem:

While in Soft-Off state, if an external modem ring-up signal is detected, the system

will be activated and therefore can be remotely accessed. You may enable this

function in BIOS's Power Management Setup menu. (See section 3. 5)

Blinking LED in Suspend Mode:

While in Suspend mode, the LED light on the front panel of your computer will flash.

Suspend mode is entered by pressing the Green Override Power Button on your ATX

case, or by enabling the Power Management and Suspend Mode options in BIOS's

Power Management menu. (See section 3.5)

Poly-fuse Over Current Protection:

The poly-fuse protects the system from dangerous voltages that the system might be

exposed to via keyboards or USB connectors. In case of such an exposure, the

poly-fuse will immediately be disconnected from the circuit just like a normal fuse.
