This connector supports 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 the setting through UART2 Use Infrared in

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 definitions.

11) SMBus Connector (5-1 pin SMB)
This connector allows you to connect SMBus devices. SMBus devices commu-
nicate by means of the SMBus with an SMBus host and/or other SMBus de-
vices. The SMBus or System Management Bus is a specific implementation of
an I
2 C bus, which is a multi-master bus, that is, multiple chips can be connected
to the same bus and each one can act as a master by initiating data transfer.
