Abstract:
An exemplary server includes a housing having a lateral side defining four openings, and a foot pad fixed in each of the openings. The foot pad includes a pivoting rod and a supporting member pivotally connected to the pivoting rod. The supporting member is operable to rotate in the opening, thereby the supporting member being totally received in the opening, or a part of the supporting member protruding outwardly from the opening for supporting the housing.

BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The disclosure relates to servers, and particularly to a server with foot pads. 
         [0003]    2. Description of Related Art 
         [0004]    With increasing heavy use of on-line computer applications, the need for computer data centers has increased rapidly. Container data centers are centralized computing facilities that include many servers, often arranged on server racks or shelves. Typically, the servers are stacked within each server rack. When each server is removed from the server rack to be placed on the floor/ground, four foot pads are mounted on a bottom of the server for preventing the server from directly contacting the floor/ground. The foot pads are secured on the bottom of the server by a plurality of screws. When the server is reinstalled into the server rack, the foot pads need to be detached from the server—otherwise the foot pads would interfere with the server rack. It is inconvenient to mount and detach the foot pads onto and from the servers. 
         [0005]    What is needed, therefore, is a server which can overcome the above-mentioned limitations.

     DETAILED DESCRIPTION 
       [0012]    Referring to  FIG. 1 , part of a container data center  100  comprising a plurality of servers  20  in accordance with an exemplary embodiment of the disclosure is shown. The container data center  100  further comprises a hollow cuboid rack  10 . The servers are stacked on the rack  10 . 
         [0013]    Each of the servers  20  comprises a housing  25  and a plurality of foot pads  30  mounted on a lateral side  21  of the housing  25 . When the server  20  is disassembled from the rack  10  to be arranged on the floor/ground, the lateral side  21  is taken as a bottom of the server  20 . Referring to  FIGS. 2-3  also, the lateral side  21  of the housing defines a plurality of rectangular openings  22  therein. The openings  22  correspondingly accommodate the foot pads  30  therein. Each of the foot pads  30  comprises a fixing member  31 , a pivoting rod  33 , and a supporting member  35  pivotally connected to the pivoting rod  33 . 
         [0014]    The fixing member  31  of each foot pad  30  is a box. The fixing member  31  comprises an open side  310  facing a corresponding opening  22 , a bottom wall  311  opposite to the open side  310 , two first sidewalls  315  extending from two elongated edges of the bottom wall  311  to the open side  310 , and two second sidewalls  316  extending from another two edges of the bottom wall  311  to the open side  310 . The bottom wall  311  cooperates with the first sidewalls  315  and the second sidewalls  316  to define a receiving space  318 . Four flanges  317  respectively extend outwardly from top ends of the first and second sidewalls  315 ,  316 . The flanges  317  are coplanar with the open side  310 . In assembly, the flanges  317  are fixed to an inner face of the lateral side  21  of the housing  25 . 
         [0015]    The bottom wall  311  of the fixing member  31  has a stepped configuration, and comprises a first part  312 , a second part  314 , and a connecting part  313  connecting the first part  312  and the second part  314 . The first part  312  is parallel to the second part  314 . The connecting part  313  is substantially perpendicular to the first part  312  and the second part  314 . A length of the first part  312  is substantially equal to that of the second part  314 . The second part  314  is nearer to the flanges  317  than the first part  312 ; that is, a distance between the second part  314  and the flanges  317  is smaller than that between the first part  312  and the flanges  317 . The receiving space  318  consists of a first portion  3180  defined corresponding to the first part  312 , and a second portion  3182  defined corresponding to the second part  314 , whereby a depth of the first portion  3180  is larger than that of the second portion  3182 . A pivoting hole  3150  is defined in each of the first sidewalls  315 . The two pivoting holes  3150  are located adjacent to the connecting part  313  of the bottom wall  311  and face each other. Two opposite ends of the pivoting rod  33  are pivotally received in the two pivoting holes  3150 , respectively. 
         [0016]    A pair of holding portions  319  are formed in each of the first sidewalls  315 . The pair of holding portions  319  are symmetrical relative to the pivoting rod  33 . Each holding portion  319  comprises a U-shaped through slot  3191  defined in a corresponding first sidewall  315 , an elastic section  3192  surrounded by the through slot  3191 , and a protrusion  3193  protruding from the elastic section  3192  toward an inside of the receiving space  318 . 
         [0017]    The supporting member  35  is a substantially rectangular block. A through hole  353  is defined at an end of the supporting member  35 . The pivoting rod  33  is received in the through hole  353 , and the supporting member  35  is capable of rotating relative to the pivoting rod  33 . A curved opening  351  is defined at an opposite end of the supporting member  35 , for facilitating a user to operate the supporting member  35 . Two recesses  355  are respectively defined in top and bottom faces of the supporting member  35 . A distance between each recess  355  and the pivoting rod  33  is equal to that between the protrusion  3193  of a corresponding holding portion  319  and the pivoting hole  3150 , for the protrusion  3193  to be engagingly received in the recess  355 . 
         [0018]    In use, referring to  FIGS. 2 and 3  again, the foot pads  30  of the server  20  are held in a first state, and the supporting members  35  of the foot pads  30  are totally received in the first portions  3180  of the fixing member  31 , respectively. When the server  20  is to be placed on the floor/ground, the supporting members  35  are correspondingly rotated relative to the pivoting rods  33  one by one, until the supporting members  35  are correspondingly received in the second portions  3182  of the fixing members  31 , and the recesses  355  snappingly receive the protrusions  3193  of corresponding holding portions  319  again, as shown in  FIGS. 4-5 . Thereby, the foot pads  30  are held in a second state. Because the depth of the first portion  3180  is larger than that of the second portion  3182  of the receiving space  318  of each fixing member  31 , the corresponding supporting member  35  is partially received in the second portion  3182 . That is, at least a part of the supporting member  35  protrudes outwardly from the second portion  3182  of the fixing member  31  and a corresponding opening  22  of the housing  25 , and acts as a supporting structure. The four supporting structures contact the floor/ground to prevent the housing  25  of the server  20  from directly contacting the floor/ground. 
         [0019]    It is to be understood, however, that even though numerous characteristics and advantages of various embodiments have been set forth in the foregoing description, 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.
