9) PWR_LED (System Power LED Header)
This header can be used to connect a system power LED on the chassis to indicate system power
status. The LED is on when the system is operating. The LED keeps blinking when the system is
in S1 sleep state. The LED is off when the system is in S3/S4 sleep state or powered off (S5).

10) F_AUDIO (Front Panel Audio Header)
The front panel audio header supports Intel High Definition audio (HD) and AC'97 audio. You may
connect your chassis front panel audio module to this header. Make sure the wire assignments of
the module connector match the pin assignments of the motherboard header. Incorrect connection
between the module connector and the motherboard header will make the device unable to work
or even damage it.
For AC'97 Front Panel Audio:
• The front panel audio header supports HD audio by default. If your chassis provides an
AC'97 front panel audio module, refer to the instructions on how to activate AC'97 functioninality
via the audio software in Chapter 5, "Configuring 2/4/5.1/7.1-Channel Audio."
• Audio signals will be present on both of the front and back panel audio connections
simultaneously. If you want to mute the back panel audio (only supported when using an HD
front panel audio module), refer to Chapter 5, "Configuring 2/4/5.1/7.1-Channel Audio."
• Some chassis provide a front panel audio module that has separated connectors on each
wire instead of a single plug. For information about connecting the front panel audio
module that has different wire assignments, please contact the chassis manufacturer.
