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.
6) F_PANEL (Front Panel Header)
Connect the power switch, reset switch, speaker, chassis intrusion switch/sensor 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.
System Status LED
S0 On
S3/S4/S5 Off
PW (Power Switch):
Connects to the power switch on the chassis front panel. You may

to Chapter 2, "BIOS Setup," "Power," 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.
PLED/PWR_LED (Power 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).
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.
NC: No connection.

panel audio module to this header. Make sure the wire assignments of the module connector match the
pin assignments of the motherboard header. Incorrect connection between the module connector and the
motherboard header will make the device unable to work or even damage it.
Some chassis provide a front panel audio module that has separated connectors on each wire instead
of a single plug. For information about connecting the front panel audio module that has different wire
assignments, please contact the chassis manufacturer.
