<p>The disk array system (500) includes: controller modules (10), power source modules (40), and battery modules (50) of a basic chassis (100); enclosure modules (70) and power source modules (80) of an expanded chassis (200); and operation levers (5) which are commonly used for operations of insertion/removal and fixation of the modules. The operation lever includes a rotary shaft portion (8) serving as a fulcrum point, a lever main body (9) and a latch (6) portion located on one side of the lever, and a hook portion (7) located on the other side thereof. When a module is inserted and fixed, a user rotates the lever main body. By this means, the latch portion and the hook portion are fixed to a receiving portion and the module is connected and fixed to the backboard with a connector.
