Chassis Intrusion
The Chassis Intrusion header is connected through a two wire cable to a switch assembly that is
mounted just under the chassis cover on systems that support this feature. When the chassis
cover is removed, the switch and thus the electrical connection between the pins on this header
become open allowing the Emulex* PILOT III BMC’s CHASIS_N pin to be pulled LOW. The
Emulex* PILOT III BMC’s CHASIS_N pin is used by Firmware to note the change in the chassis
cover status. Header on baseboard can be unstuffed by default a shorting resistor will be
needed to close the circuit.
