Connecting Case Open
The “CASE OPEN” header provides chassis intrusion-monitoring function. To
make this function work, 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.
