1-30 Chapter 1: Product introduction
10. Chassis intrusion connector (4-1 pin CHASSIS)
This connector is for a chassis-mounted intrusion detection sensor
or switch. Connect one end of the chassis intrusion sensor or switch
cable to this connector. The chassis intrusion sensor or switch sends
a high-level signal to this connector when a chassis component
is removed or replaced. The signal is then generated as a chassis
intrusion event.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted
with a jumper cap. Remove the jumper caps only when you intend to
use the chassis intrusion detection feature.
9. Front panel audio connector (10-1 pin AAFP)
This connector is for a chassis-mounted front panel audio I/O module
that supports either HD Audio or legacy AC’97 audio standard.
•
We recommend that you connect a high-denition front panel
audio module to this connector to avail of the motherboard’s high-
denition audio capability.
• By default, this connector is set to AC97 Audio. If you want to
connect a High Denition front panel audio module to this connector,
set the Front Panel Support Type item in the BIOS to [HD Audio].
