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.

•PW (Power Switch):
Connects to the power switch on the chassis front panel. You may
congure the wayto turnoff yoursystemusing thepower switch
(refer to Chapter 2, "BIOS Setup,""Settings\PlatformPower,"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 (ResetSwitch):
Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer
ifthecomputerfreezesandfailstoperformanormalrestart.
•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:Noconnection.
10) F_AUDIO (Front Panel Audio Header)
ThefrontpanelaudioheadersupportsHighDenitionaudio(HD).Youmayconnectyourchassisfront
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.
