22) Chassis Open Alarm Lead (4-1 pin CHASSIS) This lead is intended for a chassis designed to support intrusion detection. The lead requires an external detection mechanism such as a chassis intrusion monitor/sensor or microswitch. When any chassis component is removed, the sensor is triggered and a high-level signal is sent to this lead to record a chassis intrusion event. The event is then be processed by software such as LDCM. When not using the chassis intrusion lead, place a jumper cap over the pins to close the circuit. Removing the jumper cap will prevent the system from booting up. CHASSIS A7V333 ® A7V333 Chassis Alarm Lead +5VSB_MB Chassis Signal GND ASUS A7V333 motherboard user guide 41
