3. HARDWARE SETUP 10) Chassis Intrusion Lead (4-1 pin CHASSIS) This requires an external detection mechanism such as a chassis intrusion monitor/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 detector is triggered. This function works with an optional ASUS CIDB chassis intrusion 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. +5V IRRX GND IRTX 3.

11) Standard and Consumer Infrared Module Connector (5-pin IR)
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.
