DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1, a server system in accordance with an embodiment includes a rack 10 and a plurality of hosts 500 (only two hosts 500 are shown in FIG. 1). The rack 10 includes a base 11 and four supports 13 secured to the base 11. In one embodiment, the supports 13 are substantially perpendicular to a top surface of the base 11.
Referring to FIGS. 2-3, the host 500 is configured to be secured to the supports 13 and includes a chassis 20. The chassis 20 includes a bottom plate 21, a front plate 22, two opposite side plates 23, a rear plate 25, a first cover 27, and a second cover 29. The front plate 22, the side plates 23 and the rear plate 25 are located on the bottom plate 21. The side plates 23 are connected between the front plate 22 and the rear plate 25. An opening 24 is enclosed by the front plate 22, the side plates 23 and the rear plate 25. In one embodiment, the front plate 22, the side plates 23 and the rear plate 25 are substantially perpendicular to the bottom plate 21, and the side plates 23 are substantially perpendicular to the front plate 22 and the rear plate 25. The first and second covers 27, 29 are used to cover the opening 24.
A motherboard 30 is secured to the bottom plate 21. A first heat sink 50 and a second heat sink 70 are located on the motherboard 30, for cooling chips (not shown) such as CPUS. A plurality of memory cards 60 are engaged in sockets (not labeled), which are located on the motherboard 30. In one embodiment, the memory cards 60 are substantially parallel to the side plates 23.
A plurality of first connectors 223, second connectors 225 and third connectors 227 are located on the front plate 22, adjacent one side plate 23. A power connector 221 is located on the front plate 22, adjacent another side plate 23. The first to third connectors 223, 225, 227, and the power connector 221 are electronically coupled to the motherboard 30.
A supporting flange 230 is located on a top edge of each side plate 23. A locking hole 2302 (shown in FIG. 5) is defined in each supporting flange 230. A securing piece 231 with a securing hole (not shown) is bent inward from an edge of each side plate 23, which is adjacent the front plate 22. A power supply bracket 80 is secured to one of the side plates 23, above the motherboard 30, but below the corresponding supporting flange 230, for receiving a power supply. A plurality of fans 40 is secured to the rear plate 25, above the motherboard 30.
Two positioning flanges 271 are bent down from opposite edges of the first cover 27. Two mounting pieces 273 each with a mounting hole (not shown) are located on the opposite edges of the first cover 27. Two through holes 2732 (shown in FIG. 5) are defined in the first cover 27, adjacent the two positioning flanges 271. A plurality of recesses 275 is defined in the first cover 27, for receiving disk drives 90. A first securing slot 2751 and a second securing slot 2753 are defined in each of opposite sides of each recess 275. In one embodiment, the first securing slot is substantially L-shaped, and the second securing slot 2753 extends in a vertical direction.
Referring to FIGS. 2-6, in assembly, the first cover 27 is placed on the chassis 20. The mounting pieces 273 are positioned between the securing pieces 231, with the mounting holes corresponding to the securing holes. Two first fasteners 200, such as screws, are engaged into the mounting holes and the securing holes, to rotatably secure the first cover 27 to the chassis 20. The second cover 29 is secured to the chassis 20 on the rear plate 25 and the side plates 23.
The first cover 27 can be rotated between a first position (shown in FIG. 2), where the first cover 27 is rotated to abut the side plates 23 of the chassis 20, and a second position (shown in FIG. 5), where the first cover 27 is rotated out of the chassis 20. In the first position, the first cover 27 and the second cover 29 together cover the opening 24 of the chassis 20.
When the first cover 27 is in the first position, the through holes 2732 of the first cover 27 is aligned with the locking holes 2302 of the side plates. Two second fasteners 300, such as screws, are screwed into the through holes 2732 and the locking holes 2302, to stably secure the first cover 27 to the side plates 23 of the chassis 20. In one embodiment, the first cover 27 is engaged with the second cover 29 when in the first position.
Referring to FIG. 3, each disk drive 90 includes two opposite sidewalls 94. A first positioning post 91 and a second positioning post 93 are located on each sidewall 94. Referring also to FIGS. 2 and 4, in assembly, the first positioning posts 91 of each disk drive 90 are engaged in the first securing slots 2751 of each recess 275, and the second positioning posts 93 of each disk drive 90 are engaged in the second securing slots 2753 of each recess 275. Therefore, the disk drives 90 are secured to the recesses 275 of the first cover 27, and can be rotated along with the first cover 27.
Referring to FIGS. 1 and 7, the hosts 500 are secured to the rack 10, by known means, such as screws or rails. Since, the first cover 27 can be rotated from the first position to the second position, the server system is very convenient to check, maintain, or replace electronic elements, which are mounted in the chassis 20.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
