4. Chassis open alarm lead (4-1 pin CHASSIS)
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.

If you do not wish to use the chassis intrusion lead, place a jumper cap
over the pins labeled “Chassis Signal” and “Ground” to close the
circuit.
