6) Chassis Intrusion Lead (4-1 pin CHASSIS)
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 requires the optional ASUS CIDB chassis intru-
sion module to be installed (see 7. APPENDIX). If the chassis intrusion lead is
not used, a jumper cap must be placed over pins 3 & 4 to close the circuit.
