11) 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 con-
nector 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.
• 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 functionality 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 simultane-
ously. 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.
12) F_USB1/F_USB2 (USB Headers)
The headers conform to USB 2.0/1.1 specification. Each USB header can provide two USB ports via an
optional USB bracket. For purchasing the optional USB bracket, please contact the local dealer.
• Do not plug the IEEE 1394 bracket (2x5-pin) cable into the USB header.
• Prior to installing the USB bracket, be sure to turn off your computer and unplug the power
cord from the power outlet to prevent damage to the USB bracket.
