An Expander expansion plate is arranged between the rear lower layer back plate and the lower layer fan.
The number of the front upper layer back plate, the front lower layer back plate and the rear lower layer back plate is one, and the number of the back plates is 12. The number of the rear upper layer back plates is two, the number of the rear upper layer back plates is 2, and the two rear upper layer back plates are arranged along the left-right direction.
As shown in fig. 1 and fig. 2, correspondingly, the front window 1 of the server is provided with 24 pieces of 3.5 inches hard disks, the rear window 2 of the server is provided with 16 pieces of 3.5 inches hard disks, and the hard disks support hot plugging. In order to support hot plugging of the hard disk, firstly, the server needs to meet the requirement in the aspect of structure that the hard disk can be plugged and unplugged without disassembling other components such as a case and the like, and secondly, the server needs to meet the requirement of protection function in the aspect of circuit connection. It can be seen from the figure that the service satisfies the requirement of hot plug in terms of structure, and the circuit connection supporting hot plug belongs to the prior art, and is not described herein again.
