Fan Headers
To facilitate the connection of 3 x40mm double rotor fans, a 14 pin header is provided, all fans
will share a PWM.
Both rotor tachs can be monitored.

NODE_PWRGD
The SMBus* is used to connect to the hot swap controller that provides inrush current protection
and can measure the power being used by the node.
The NODE_ON signal is used to turn on
the hot swap controller.
Note that the polarity is correct as the ADI1275 controller uses a high
true enable signal.
When the node is turned off, the fans will continue to rotate at a preset rate;
this rate is selected by Intel
®
and preset by the Fan manufacturer. This is done to stop air
recirculation between nodes.
When docking the board to a live 12V rail, the fans could spin up
immediately; it may be required to phase their connection to power to minimize the inrush
current. Bench testing of the fans should determine if this is necessary.

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 Server Engines PILOT III BMC’s CHASIS_N pin to be pulled LOW.
The Server Engines 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.
