11. 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.
Never connect a USB cable to the IEEE 1394 connectors. Doing so will
damage the motherboard!
12. IEEE 1394 connector (10-1 pin IE1394_2)
This connector is for the IEEE 1394a module. Connect the IEEE 1394
module cable to this connector, then install the module to a slot
opening at the back of the system chassis.
