9. Chassis alarm lead (4-1 pin J2)
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 shorted
with a jumper cap. If you wish to use the chassis intrusion detection
feature, remove the jumper cap from the pins.
10. SMBus connector (6-1 pin J5)
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.
