8)Chassis Intrusion LeadThis requires an external detection mechanism such as a chassis intrusion moni- tor/sensor or microswitch. The sensor is triggered when a high level signal is sent to the Chassis Signal lead, which occurs when a panel switch or light detec- tor is triggered. This function works with an optional ASUS CIDB chassis intru- sion module (see your vendor for more details). If the chassis intrusion lead is not used, a jumper cap must be placed over the pins to close the circuit.

CHASSIS
This connector supports an optional wireless transmitting and receiving infrared module. This module mounts to a small opening on system cases that support this feature. You must also configure the setting through UART2 Use Infrared (see 4.4.2 I/O Device Configuration) to select whether UART2 is directed for use with COM2 or IrDA. Use the five pins as shown in Back View and connect a ribbon cable from the module to the motherboard’s SIR connector according to the pin definitions.
