9) 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.
• PW (Power Switch):
Connects to the power switch on the chassis front panel. You may
congure the way to turn off your system using the power switch
(refer to Chapter 3, "BIOS Setup," "Power Management," for more
information).
• SPEAK (Speaker):
Connects to the speaker on the chassis front panel. The system reports
system startup status by issuing a beep code. One single short beep
will be heard if no problem is detected at system startup.
• 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.
• PLED/PWR_LED (Power LED):
System Status LED
S0 On
S3/S4/S5 Off
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).
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 assignments are
matched correctly.
• 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.
• NC: No connection.
