Therefore, through the construction of the embodiments above, when the dummy chassis is assembled and disassembled, the above-mentioned embodiments of the present disclosure provide the following advantages: 1. the tool-free assembly requirements of the dummy chassis is realized; 2. mutual foolproof mechanism for the assembly of the dummy chassis is provided; and 3. when the dummy chassis is idle, the dummy chassis can be quickly minified so as to achieve the advantages of size reduction and space occupation.

In one embodiment of the disclosure, a server rack is provided, and the server rack includes a rack body, two sliding rails, a power socket and a dummy chassis. The rack body includes a front end and a rear end which are opposite to each other. The sliding rails are fixedly connected to two opposite inner sides of the rack body, respectively. The power socket is disposed on the rear end of the rack body. The dummy chassis is slidably disposed on the sliding rails, and includes a first frame bar, a second frame bar and a connection member. The first frame bar is disposed on the front end of the rack body, and provided with a first long side. The second frame bar covers the power socket, and is provided with a second long side. The connection member has a first end portion and a second end portion which are located oppositely. The first end portion is detachably connected to the first long side of the first frame bar, and the second end portion is detachably connected to the second long side of the second frame bar. The width of the connection member is less than the length of the first frame bar and a length of the second frame bar.
