Abstract:

After a variety of hot swap control strategies are  studied,this paper intends to design a hot swap circuit for the blade plugins with 12V power bus structure of the new generation high performance computer system.With the PMBusTM communication interface of the latest control technology,the measurement,protection,control and test of the hot swap circuit for the power bus of the blade plugins has been realized in this paper.The design techniques will be applied to a new generation of super computer plugin boards.

Key words: blade plugins；hot swap；PMBusTM；power bus
