    • In a swappable data access unit rack structure installable in a computer casing, a chassis is a box body composed of a lower casing, a front frame, a rear panel and an upper casing. The front frame has a frame hole, a transversal long hole at its upper edge, and a frame at the rear of the front frame. An upper distal surface of the frame is of the same height with a lower edge of the long hole of the front frame. A rack panel is fixed at the upper edge of the inner side of the lower casing. The long hole, the upper distal surface of the frame and the rack panel define a horizontal bay and a tray for carrying a data access unit. The tray is slidably slid into the bay and mounted across the upper distal surface of the frame and the rack panel.
    • 在可安装在计算机外壳中的可交换数据存取单元机架结构中,底盘是由下壳体,前框架,后面板和上壳体组成的盒体。 前框架具有框架孔,其上边缘处具有横向长孔,并且在前框架的后部具有框架。 框架的上远端表面与前框架的长孔的下边缘具有相同的高度。 机架面板固定在下壳体内侧的上缘。 长孔,框架的上远端表面和搁板面板限定水平托架和用于承载数据存取单元的托盘。 托盘可滑动地滑入隔间并安装在框架和机架面板的上远端表面上。
