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.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may congure
the way to turn o your system using the power switch.
RESET (Reset Switch):
Connect 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.
PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-
tem is in S1/S3 sleep state. The LED is o when the system is in S4 sleep
state or powered o (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED
is on when the hard drive is reading or writing data.
The front panel design may dier 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 assign-ments are
matched correctly.
