12) 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.

11) Chassis Intrusion Lead (2 pin CHASSIS)
This 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 requires the optional ASUS CIDB chassis intru-
sion module to be installed (see 7. APPENDIX). If the chassis intrusion lead is
not used, a jumper cap must be placed over the pins to close the circuit.
