Chapter 2 INSTALLATION
NOTE: The CPU and/or motherboard will overheat if there is no airflow
across the CPU and onboard heat sinks. Damage may occur to the
motherboard and/or the CPU fan if these pins are incorrectly used. These
are not jumpers, do not place jumper caps over these pins.
19. IrDA Infrared Connector (J15, Front IrDA; J17, Rear IrDA)
These connectors support the 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 USRT 2 Use Infrared in Chipset Features Setup to
select whether UART2 is directed for use with COM2 or IrDA.
When IrDA is selected in BIOS, COM2 will be disabled. Use the
five pins as shown on the Back View and connect a ribbon cable
from the module to the motherboard to the pin definitions.
