3 Chassis intrusion connector (4-1 pin CHASSIS)

This connector is for a chassis-mounted intrusion detection sensor or switch.

Connect one end of the chassis intrusion sensor or switch cable to this

connector. The chassis intrusion sensor or switch sends a high-level signal to

this connector when a chassis component is removed or replaced. The signal

is then generated as a chassis intrusion event.

By default, the pins labeled “Intruder” are shorted with a jumper cap. Remove

the jumper caps only when you intend to use the chassis intrusion detection

feature.
