ABSTRACT:
An escape sequence coded in power commands from a system controller, such as a BMC, to a cooling fan controller directs the cooling fan to send identification information coded in tachometer readings to the system controller for use by an information handling system. Electronic confirmation of the cooling fan identification ensures compatibility of the information handling system and cooling fan at initial manufacture or subsequent repair. Communication of information over existing power and tachometer wires supports the electronic confirmation without adding additional communication lines. Further, once a communication link is established between an information handling system controller and a cooling fan, other functions are enabled, such as a reflash of the cooling fan controller firmware.
