2-22 Chapter 2: Hardware information
9. Line out selector (2-pin LO_L, LO_R) (on audio models only)
By default, these jumpers are shorted (jumper caps on) to route the
signal from the audio controller to the rear panel Line Out jack to make
it available for audio out devices such as speakers or a headphone. If
you connect the Intel Front Panel audio cable to the AAPANEL
connector (see page 2-30 for the location), remove the caps from
these jumpers to allow automatic switching of audio signal between the
rear panel Line Out jack and the Intel audio cable.
10. LAN setting (3-pin LAN_ENABLE) (on LAN models only)
This jumper allows you to enable or disable the onboard Local Area
Network (LAN) feature. Keep the default setting Enabled if you wish to
connect your computer to a network.
