17. Chassis Open Alarm lead (4-1 pin CHASSIS1)
This lead is intended for a chassis that supports 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 prevents
the system from booting up.
