Abstract: An electronic device includes a chassis, first and second sliding tray modules, first and second cables, and first and second cable-protecting members. The chassis includes a main sliding rail and has a bottom surface. The first and second sliding tray modules respectively contain a plurality of first and second storage modules. The first and second cables are respectively electrically connected to the first and second storage modules. The first cable-protecting member includes a plurality of first connecting units pivotally connected one by one. The first connecting units retain the first cable to move at a first height relative to the bottom surface. The second cable-protecting member includes a plurality of second connecting units pivotally connected one by one. The second connecting units retain the second cable to move at a second height relative to the bottom surface. The first height is different from the second height.
