System and method for implementing RMII Ethernet reset of a slave card is described. In one embodiment, the invention comprises a method of resetting a slave card electrically connected to an administrative processor of a system via a Reduced Media Independent Interface (“RMII”) Ethernet physical layer device (“PHY”). The method comprises, responsive to detection of a start of frame indicator (“SFI”), activating a shift register; shifting reset signal data into the shift register; comparing the reset signal data shifted into the shift register with compare data; and responsive to the reset signal data being the same as the compare data, resetting the slave card.
