The invention discloses an I2C link system based on a CPLD (Complex Programmable Logic Device) and a server. The system comprises a first mainboard, downstream equipment and a CPLD chip, a first I2C signal of the first mainboard is transmitted to the CPLD chip, the CPLD chip performs level shift on the received first I2C signal, and after logic processing, the corresponding first I2C signal is transmitted to the corresponding downstream equipment through a multiplexer in the CPLD chip. The server is configured with the system. The I2C signal of the mainboard is transmitted to the CPLD chip, the CPLD chip performs logic processing, and the corresponding I2C signal is transmitted to the corresponding downstream equipment through the multiplexer of the CPLD chip, so that the CPLD chip replaces numerous voltage level conversion chips and IO expansion chips, a large amount of board card space is saved, board card design is facilitated, and design cost is saved. 本发明公开一种基于CPLD的I2C链路系统及服务器，系统包括第一主板、下游设备和CPLD芯片；第一主板的第
