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, 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.
• 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 (ResetSwitch,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):

removed. This function requires a chassis with a chassis intrusion switch/sensor.
• NC (Orange): No Connection.
10) SPDIF_O (S/PDIF Out Header)
This header supports digital S/PDIF Out and connects a S/PDIF digital audio cable (provided by
expansion cards) for digital audio output from your motherboard to certain expansion cards like graphics
cards and sound cards. For example, some graphics cards may require you to use a S/PDIF digital
audio cable for digital audio output from your motherboard to your graphics card if you wish to connect
an HDMI display to the graphics card and have digital audio output from the HDMI display at the same
time.
For information about connecting the S/PDIF digital audio cable, carefully read the manual for your
expansion card.
