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.
15) 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, Red):
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," 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):
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,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.
