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