12) PWR_LED
The PWR_LED connector is connected with the system power indicator to indicate whether the
system is on/off. It will blink when the system enters suspend mode.
13) F_AUDIO (Front Audio Connector)
This connector supports either HD (High Definition) or AC97 front panel audio module. If you wish
to use the front audio function, connect the front panel audio module to this connector. Check the pin
assignments carefully while you connect the front panel audio module. Incorrect connection
between the module and connector will make the audio device unable to work or even damage it.
For optional front panel audio module, please contact your chassis manufacturer.
By default, the audio driver is configured to support HD Audio. To connect an AC97 front panel
audio module to this connector, please refer to the instructions on page 84 about the software
settings.
