1-L 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-M Creative Labs Audio Connectors

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 is turned into an audio signal which goes out through the speaker. The TDA connector (J21) is for modem audio; the MPEG connector (J20) is for DVD and TV cards; the VIDEO connector is (J22); the CD connector (J23) is for CD-ROMs.

1-N External SMI

The EXTSMI (External System Management Interface) connector, jumper JP16, is used by some plug-in cards. Certain applications associated with these plug- in cards use the interface for hardware control and queries.

1-O Intrusion Alarm Connector

The J7 connector is an intrusion alarm, that can be connected to the system chassis. When active (J7 is connected to the chassis), this alarm will alert the system administrator anytime someone opens the system’s case.

1-P Power LED Connector

Jumper D31 is a three pin power LED header that can be used if you have a 3 pin Power LED. Otherwise refer to panel connector J16 for 2 pin LEDs. 3 pin LED’s can still be used on J16 where pin 13 would be for the Ground pin.

The Real Time Clock (RTC) circuit, which provides the date and time for the system is integrated into the 440BX or Via Apollo Pro Plus AGPset. If the external battery for the RTC is low, it will prevent your system from POSTing, and you will not get a display. Normally the life span of an external battery is 2 years. If yours is running low, you will need to replace it with a new 3V lithium battery (Sony CR2032).
