13) F_PANEL (Front Panel Header)
Connect the power switch, reset switch, 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):
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).
• 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.
• NC: No connection.
• PLED (Power LED):
System Status LED
S0 On
S3/S4/S5 Off
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).
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 and etc. When connecting your chassis
front panel module to this header, make sure the wire assignments and the pin assignments are
matched correctly.
