This section describes and illustrates the internal connectors on the motherboard.
1. Hard disk activity LED (2-pin IDE_LED1)
This connector supplies power to the hard disk activity LED. The read or write
activities of any device connected to the primary or secondary IDE connector
cause this LED to light up.

2. 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.
