US 8,045,336 B2 · Storage device backplane and identification circuit

Abstract

A storage device backplane and an identification circuit for identifying using situations of the storage device backplane are provided. The storage device backplane possesses a first connection interface and a second connection interface, for being used as a first backplane supporting a motherboard, or a second backplane cascaded to the first backplane, or a first backplane supporting a daughterboard of the motherboard. The first and second backplanes possess the same storage device backplane structure. If the storage device backplane is used as the first backplane, a first connection interface of the first backplane is coupled to the motherboard or the daughterboard thereof; if the storage device backplane is used as the second backplane, a first connection interface of the second backplane is coupled to a second connection interface of the first backplane. The identification circuit identifies using situations of the storage device backplane and display corresponding correct indicator number.
