In the prior art, a conventional NCSI design at a motherboard end is shown in fig. 1, where a NCSI connector is provided on a motherboard, the NCSI connector is used to connect a network card, and a 50MHz clock is provided, one of the NCSI connector (50 MHz clock line 1 in fig. 1) is sent to a BMC, and the other NCSI connector (50 MHz clock line 2 in fig. 1) is sent to the network card through a cable. After receiving the clock, the network card sends data to the BMC through internal delay of a chip; because the link for receiving data by the BMC is long and the link for receiving the clock is short, the NCSI establishment time of the BMC end cannot meet the design requirement.
