15)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. Opening the chassis triggers the sensor and a high-level signal is sent to this lead to record the 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 without attaching any detectors prevents boot-up of the PC.
