23)Chassis Open Alarm Lead (4-pin CHASSIS)

This lead is designed for chassis intrusion detection. It requires an external detection mechanism such as a chassis intrusion monitor/sensor or microswitch. When the chassis is opened, 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.

NOTE: Removing the chassis intrusion jumper cap without attaching any detectors prevents boot-up of the PC.
