Gigabyte B450M DS3H User Manual

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.
9) 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.

S3/S4/S5 Off
• PW (Power Switch):
Connects to the power switch on the chassis front panel. You may
congure theway to turn offyour system using the power switch
(refertoChapter2,"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.
• 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.
10) F_AUDIO (Front Panel Audio Header)
 ThefrontpanelaudioheadersupportsHighDenitionaudio(HD).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.
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.
