7. 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.

I/O lines are programmable and each I/O pin can be individually programmed
to support various devices.
