Gigabyte B550M AORUS ELITE AX 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.
11) 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
congure the way to turn off your system using the power switch
(refer to Chapter 2, "BIOS Setup," "Settings\Platform 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.
