5/8-SPEAK/FPANEL(Speaker Headers & Front Panel Switches)
HD_LED (Red): Hard Driver LED connector
This connector connects to the case-mounted
HD LED cable, and the LED will light when the
hard drive(s) is/are being accessed.
RST (Blue): Reset Switch
This connector connects to the case-mounted
reset switch which allows you to reboot without
having to power-off the system and thus prolonging the life of the power supply or system.
PWR_ON (Black): Power Switch
Depending on the setting in the BIOS setup, this switch serves two functions which will allow
you to power-on/off the system or to enter the suspend mode.
PWR_LED (Green): Power/Standby LED
When the system's power is on, this LED will light. When the system is in the S1 (POS - Power
on Suspend) or S3 (STR - Suspend to RAM, optional) state, it will blink every second.

4-JBAT(CMOS Memory Clearing Header)
The time to clear the CMOS memory occurs when (a) the CMOS data becomes corrupted, (b)
you forgot the supervisor or user password preset in the BIOS menu, (c) you are unable to
boot-up the system because the CPU ratio/clock was incorrectly set in the BIOS menu, or (d)
whenever there is modication on the CPU or memory modules.
This header uses a jumper cap to clear the CMOS
memory and have it recongured to the default values
stored in BIOS.
• Pins 1 and 2 shorted (Default): Normal operation.
• Pins 2 and 3 shorted: Clear CMOS memory.

3-S/PDIF Output Connection Header
S/PDIF (Sony/Philips Digital Interface) is a standard audio transfer le format.
It is usually found on digital audio equipment such as a DAT (Digital Audio
Tape) machine or audio processing device. It allows the transfer of audio from
one le to another without the conversion to and from an analog format, which
could degrade the signal quality.
