3. HARDWARE SETUP
11) Chassis Intrusion Lead (2 pin CHASS)
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 works with an optional ASUS CIDB chassis intru-
sion module (see your vendor for more information). If the chassis intrusion
lead is not used, a jumper cap must be placed over the pins to close the circuit.

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.
