11) Chassis Intrusion Lead (4-1 pin CHASSIS)
This requires an external detection mechanism such as a chassis intrusion monitor/
sensor or microswitch. The sensor is triggered when a high level signal is sent to
the Chassis Signal lead, which occurs when a panel switch or light detector is
triggered. This function works with an optional ASUS CIDB chassis intrusion
module (see your vendor for more details). If the chassis intrusion lead is not
used, a jumper cap must be placed over the pins to close the circuit.

Secondary ATA100 connectors will cause the LED to light up.
