Gigabyte GA-AX370-Gaming K3 (rev. 1.0) [16/40] F_panel front panel header

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.

10) 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

toChapter2,"BIOSSetup,""Power,"formoreinformation).

• 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.

• PLED/PWR_LED (PowerLED,Yellow/Purple):

• 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.

11) F_AUDIO (Front Panel Audio Header)

 ThefrontpanelaudioheadersupportsHighDenition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.

• 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.
