12) Chassis Intrusion Lead (4-1 pin CHASS)
This requires an external detection mechanism such as a chassis intrusion moni-
tor/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 detec-
tor is triggered. This function works with an optional ASUS CIDB chassis intru-
sion module (see your vendor for more information). If the chassis intrusion
lead is not used, a jumper cap must be placed over the pins to close the circuit.
