According to the present invention, the power supply for each shelf of the frame is duplicated by making the numbers of the system lines of the system 0 and system 1 the same, and the power supply of the fan is duplicated in the system 0 and system 1 as in the conventional system. When connecting to a system line, if both of the redundant power supplies stop at one of the four shelves, the fan also stops with a probability of 1/4. In the case of the present invention, both of the redundant power supplies stop at the two shelves. Probability, ie (1/4) × (1
/ 4) = 1/16, and the possibility of the fan stopping is reduced.
