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.
