Abstract:
1. A disk enclosure, comprising: a plurality of disk apparatuses connected to a power source which is common to the plurality of disk apparatuses; a detection element including a plurality of resistors detecting current which flows from the power source to the plurality of disk apparatuses, each of the plurality of resistors having different detection resistance values; a detection element switching circuit switching the detection resistance values with which the detection element detects the current base on a type of each of the plurality of disk apparatuses; a control circuit controlling connection or disconnection of the power source with the plurality of disk apparatuses based on comparison between a predetermined threshold value and the potential difference between both terminals of the detection element; and a switching circuit connecting or disconnecting the power source with the plurality of disk apparatuses based on an output of the control circuit.
