4-Pin Smbus Connector(Smbus)(Optional); Chassis Security Switch(Chssec)(Optional) - QDI P5I915PL Manual

Installation Instructions

4-pin SMBus Connector(SMBUS)(optional)

This connector allows you to connect SMBus devices. SMBus devices communicate
through the SMBus with a SMBus host and/or other SMBus devices. The SMBus or
System Management Bus is a specific implementation of I
bus, that is, multiple devices can be connected to the same bus and each one can act as
a master by initiating data transfer.
Chassis Security Switch (CHSSEC)(optional)
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 monitor or check this information from some software.
