Board Installation

1-G Soft Power Connector

The Soft Power Connector is part of jumper block J16. The Trinity 400 uses the chipset for power management, including turning on and off the system. If the Power Button Function option in the BIOS Power Management Menu is set to On/Off (which is the default), pressing the power button once after the BIOS has booted up will turn the system on and off. If the Power Button Function option is set to Suspend, pressing the power button once will wake the system or send it to Suspend mode. In this case, you cannot turn the system off unless you shut down through the Windows operating system or you hold the power button down for four seconds.

1-H Hardware Reset Switch Connector Installation

The Reset switch on your case’s display panel provides you with the Hard- ware Reset function, which is the same as power on/off. The system will do a cold start after the Reset button is pushed. (J16 pin 7 & 8)

1-I Creative Labs Audio Connectors (optional)

There are four black 4-pin

 

connectors onboard which are

 

used for various peripherals’

 

audio signals. The digital signal

 

that comes in through these

 

connectors is directed through

 

the Creative Labs ES1373 PCI

 

sound chip, and the digital signal

CON3

is turned into an audio signal

(WOL)

which goes out through the

 

speaker. The TDA connector

CON2

(J21) is for modem audio; the

(WOR)

VIDEO connector is (J22); the CD

 

connector (J23) is for CD-ROMs.
