Abstract

The invention provides a communication system of a mainboard and a backboard and a server applicable to the communication system. According to the communication system of the mainboard and the backboards, the mainboard is connected with the backboards through a bus; each backboard is provided with own preset address information; and when the main board accesses a target backboard every time, the main board accesses the target backboard through the bus according to the preset address information of the target backboard. According to the communication system of the mainboard and the backboard, the wiring space of hardware design can be saved, wiring of the hardware design is more convenient, and the wiring quality is higher.

Description

technical field [0001] The invention relates to the technical field of hardware design, in particular to a communication system of a main board and a back board and an applicable server thereof. Background technique [0002] I2C interface communication is adopted by many semiconductor manufacturers for its management, communication or programming interface for integrated circuits due to its characteristics of occupying less pins and being simple and practical. At present, almost 80% of management interfaces of server systems of many companies use I2C communication. [0003] In many different types of computers, multiple hard disk backplanes with the same address will occupy more I2C interfaces. Due to the limited I2C interface of the main controller, it is inevitable to use I2C_Switch routing chips, such as PCA9548 (I2C_Switch routing chip with one channel divided into eight channels), PCA9546 (I2C_Switch routing chip and I2C repeater with one channel divided into four chan...
