Asus P5QL-EM - Manual (Page 48)

1-36 Chapter 1: Product introduction
10. USB connectors (10-1 pin USB1112, USB910, USB78)
Never connect a 1394 cable to the USB connectors. Doing so will damage the
motherboard!
The USB module is purchased separately.
9. 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.
