Asus P4P8X - Manual (Page 36)

1-26 Chapter 1: Product introduction
8. Front panel audio connector (10-1 pin FP_AUDIO)
This is an interface for the Intel front panel audio cable that allow convenient
connection and control of audio devices.
By default, the pins labeled LINE OUT_R/BLINE_OUT_R and the pins LINE
OUT_L/BLINE_OUT_L are shorted with jumper caps. Remove the caps only
when you are connecting the front panel audio cable.
9. Chassis intrusion connector (4-1 pin CHASSIS1)
This lead is for a chassis designed with intrusion detection feature. This
requires an external detection mechanism such as a chassis intrusion sensor
or microswitch. When you remove any chassis component, the sensor triggers
and sends a high-level signal to this lead to record a chassis intrusion event.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted
with a jumper cap. If you wish to use the chassis intrusion detection
feature, remove the jumper cap from the pins.
