Chassis Intrusion Connector; Front Audio Connector - AOpen AX4B-533 Installation Manual

10. Chassis Intrusion Connector

The "CASE OPEN" header provides chassis intrusion-monitoring function. To make this
function works, you have to enable it in the system BIOS, connect this header to a sensor
somewhere on the chassis. So, whenever the sensor is triggered by lights or by the
opening of the chassis, the system will beep to inform you. Please be informed that this
useful function only applies to advanced chassis, you may purchase an extra sensor,
attach it on your chassis, and make a good use of this function.

the jumper cap from the Front Audio Connector before you connect the cable. Do not

panel.
