10) SMB Connector (6-1 pin SMB)
This connector allows you to connect SMBus (System Management Bus) devices.
SMBus devices communicate by means of the SMBus with an SMBus host and/
or other SMBus devices. SMBus is a specific implementation of an I2C bus,
which is a multi-device bus; that is, multiple chips can be connected to the same
bus and each one can act as a master by initiating data transfer.
11) Chassis Intrusion Lead (2-pin ACHA)
This lead is for a chassis designed for chassis intrusion detection. After-market
toggle switches may also be installed to the chassis panel or on any removable
components. Two wires should be available from the chassis to connect to this
lead. When any chassis component is removed, the contact should open and the
motherboard will record a chassis intrusion event. The event can then be processed
by software such as LDCM. If the chassis intrusion lead is not used, a jumper
cap must be placed over the pins to close the circuit.
