11. 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 pin labeled “Chassis Signal” and “Ground” are shorted with

a jumper cap. Remove the jumper caps only when you intend to use the

chassis intrusion detection feature.

12. LPT connector

The LPT (Line Printing Terminal) connector supports devices such as a

printer. LPT standardizes as IEEE 1284, which is the parallel port interface on

IBM PC-compatible computers.
