USB Header (10-1 pin USBPORT)
If the USB port connectors on the back panel are inadequate,
one USB header is available for two additional USB port
connectors. Connect the USB header to a 2-port USB connector
set and mount the bracket to an open slot on the chassis. (The
USB connector set does not come with the motherboard
package.)
3.
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 a system chassis that supports this feature. You must also
configure the setting through UART2 Use Infrared (see 5.4.2
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 SIR connector according to the pin definitions.
