III. INSTALLATION
10. IrDA / Fast IR-Compliant infrared module connector (5-pin IR)
This connector supports the optional wireless transmitting and receiving infra-
red module. This module mounts to a small opening on system cases that sup-
port this feature. You must also configure the setting through "UART2 Use In-
frared" in Chipset Features Setup to select whether UART2 is directed for use
with COM2 or IrDA. Use the five pins as shown on the Back View and connect
a ribbon cable from the module to the motherboard according to the pin defini-
tions.

11. ATX Power Supply Connector (20-pin ATXPWR)
This connector connects to a ATX power supply. The plug from the power sup-
ply will only insert in one orientation because of the different hole sizes. Find
the proper orientation and push down firmly but gently making sure that the pins
are aligned.
IMPORTANT: Be sure that the ATX power supply can take at least 10mAmp
load on the 5volt standby lead (5VSB). You may experience difficulty in power-
ing on your system without this.
