Installation Instructions
Audio Connector (CDLIN1, MODEM, AUX_IN)
CDLIN1 is a Sony standard CD audio connector, it can be connected to a CD-ROM drive
through a CD audio cable. The MODEM connector allows the onboard audio to interface
with a voice modem card with a similar connector. It allows connecting the mono_in (such
as a phone) or mono_out (such as a speaker) between the onboard audio and the voice
modem card. AUX_IN allow you to receive stereo audio input from such sound sources as
a CD-ROM,TV tuner,or MPEG card.

4 pin SMBus Connector(SMBUS)

This connector allows you to connect SMBus devices. SMBus devices communicate by
means of the SMBus with an SMBus host and/or other SMBus devices. The SMBus or
System Management Bus is a specific implementation of an I
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.

Chassis Security Switch (CHSSEC)

The connector connects to the chassis security switch on the case. The system can
detect the chassis intrusion through the status of this connector. If the connector has
been closed once, the system will record the status and indicate the chassis has been
opened. You can receive this information from QDI ManageEasy software.
