To secure the storage device 40 in the bracket 10, the power supply 80 is rotated inward the compute chassis 90. During the rotation of the power supply 80, the retention member 58 is extended through the opening 38 of the bracket 10 to urge the guiding portion 63 of the hook 60. The convex 28 of the bracket 10 is disengaged from the hole 68 of the hook 60. The hook 60 is thus rotated toward said rear sliding member 44 until the hook end 69 clasps said rear sliding member 44. A distal end of the retention member 58 is located below the horizontal tab 64, and engages the vertical tab 62 to prevent reverse rotation of the hook 60. The first tab 52 of the power supply 80 is extended through the slot 22 of the flange 20 of the bracket 10, and the second tab 54 engages the flange 20 to prevent further rotation of the power supply 80. The catch 86 of the power supply 80 engages the groove 94 of the second wall 96 of the computer chassis 90. FIG. 5 shows the storage device 40 is fully attached to the bracket 10.
To detach the storage device 40 from the bracket 10, the power supply 80 is rotated outwardly. The distal end of the retention member 58 of the power supply 80 engages the horizontal tab 64 to pull the hook 60 rearward. The hook 60 is rotated to an original position (shown in FIG. 4) until the convex 28 of the bracket 10 snappingly engages in the hole 68 of the hook 60. The hook end 69 disengages said rear sliding member 44 of the storage device 40. The storage device 40 is thus ready to be detached from the bracket 10.
