4. Chassis intrusion connector (4-1 pin CHASSIS)
This lead is for a chassis designed with intrusion detection feature.
This requires an external detection mechanism such as a chassis
intrusion sensor or microswitch. When you remove any chassis
component, the sensor triggers and sends a high-level signal to this
lead to record a chassis intrusion event.
By default, the pins labeled “Chassis Signal” and “Ground” are
connected to the front panel microswitch. If you wish to disable the
chassis intrusion detection feature, unplug the cable from the
microswitch and place a jumper cap to these pins.
5. SMBus connector (6-1 pin SMB)
This connector allows you to connect SMBus (System Management
Bus) devices. Devices communicate with an SMBus host and/or other
SMBus devices using the SMBus interface. SMBus is a specific
implementation of an I
2
C bus, a multi-device bus that allows multiple
chips to connect to the same bus and enable each one to act as a
master by initiating data transfer.
