7) Chassis Intrusion Lead (4-1 pin CHASSIS)

This lead is for a chassis designed for chassis intrusion detection. This requires

an external detection mechanism such as a chassis intrusion monitor/sensor or

microswitch. When any chassis component is removed, the sensor is triggered

and a high-level signal is sent to this lead to record a chassis intrusion event.The

event is then be processed by software such as LDCM. When not using the

chassis intrusion lead, place a jumper cap over the pins to close the circuit.

8) SMBus 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 I

C 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.
