7. Chassis intrusion connector (4-1 pin CHASSIS1)
This lead is for a chassis designed with intrusion detection feature. This
requires an external detection mechanism such as a chassis intrusion sensor
or microswitch. When you remove any chassis component, the sensor triggers
and sends a high-level signal to this lead to record a chassis intrusion event.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted with a
jumper cap. If you wish to use the chassis intrusion detection feature, remove
the jumper cap from the pins.
