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.
8) 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.

PW
(Power Switch, Red):
Connects to the power switch on the chassis front panel.
You may configure the way to turn off your system using
the power switch (refer to Chapter 2, "BIOS Setup," "Power
Management," for more information).
•
PLED/PWR_LED
(Power LED, Yellow/Purple):
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).
•
SPEAK
(Speaker, Orange):
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, Blue):
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, Green):
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, Gray):
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
(Orange): No Connection.
•
The front panel audio header supports HD audio by default.
•
Audio signals will be present on both of the front and back panel audio connections simultaneously.
•
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.
9) F_AUDIO (Front Panel Audio Header)
The front panel audio header supports Intel High Definition audio (HD) and AC'97 audio. You may connect
your chassis front 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.
