5. IEEE 1394 connector (10-1 pin IE1394_1)

This connector is for a 1394 module. Attach the 10-1 pin 1394 cable
plug from the module to this connector. You may also connect a
1394-compliant internal hard disk to this connector.

6. Chassis intrusion connector (4-1 pin CHASSIS1)

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.

By default, the pins labeled “Chassis Signal” and “Ground” are shorted
with a jumper cap. If you wish to use the chassis intrusion detection
feature, remove the jumper cap from the pins.
