1-26 Chapter 1: Product introduction
1.10.2 Internal connectors
1. Floppy disk drive connector (34-1 pin FLOPPY)
This connector is for the floppy disk drive (FDD) signal cable. Insert one
end of the cable to this connector, then connect the other end to the signal
connector at the back of the floppy disk drive.
2. 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 “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.
• Pin 5 on the connector is removed to prevent incorrect cable connection
when using an FDD cable with a covered Pin 5.
• The floppy disk drive cable is purchased separately.
