6) F_PANEL(FrontPanelHeader)

Connect the power switch, reset switch, speaker, 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.

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.

• PW (Power Switch):

Connects to the power switch on the chassis front panel. You may congure the way to turn off your

system using the power switch (refer to Chapter 2, "BIOS Setup," "Power Management Setup," for

more information).

• SPEAK (Speaker):

Connects to the speaker on the chassis front panel. The system reports system startup status by is-

suing a beep code. One single short beep will be heard if no problem is detected at system startup. If

a problem is detected, the BIOS may issue beeps in different patterns to indicate the problem.

• HD (Hard Drive Activity LED)

Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive

is reading or writing data.

• RES (Reset Switch):

Connects 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.

• CI (Chassis Intrusion Header):

Connects to the chassis intrusion switch/sensor on the chassis that can detect if the chassis cover

has been removed. This function requires a chassis with a chassis intrusion switch/sensor.

• MSG/PWR (Message/Power/Sleep LED):

Connects to the power status indicator on the chassis front panel. The LED

is on when the system is operating. The LED is off when the system is in

S3/S4 sleep state or powered off (S5).
