4 pin SMBus Connector(SMBUS)
This connector allows you to connect SMBus devices. SMBus devices communi-
cate 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
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.
Sound Connector (PC-PCI)
This connector provides a bridge between the mainboard and PCI sound card to
deliver sound compatibility under DOS real-mode environment.
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.
