J29 Chassis Door Intrusion J29 is a 2-pin berg that can be used to attach a wire to the chassis door intrusion connector, if the chassis has this feature. The logic must be set so that Pin 1 and Pin 2 are shorted when the chassis door is closed and open when the chassis door is opened.

J18 External SMI J18 is a 3-pin berg. An external SMI (System Management Interrupt) source can be connected to J18. When an external SMI needs to generate an SMI to the system, Pin 1 must be shorted to Pin 2 (as a pulse).
