And if you want to expand the number of PC servers as needed, the space area occupied by the PC server array is increased, so there is a problem in that it is limited in terms of space utilization. There is a disadvantage that the maintenance for the maintenance is not easily made due to the complicated tangled cables.

Therefore, the object of the present invention is to eliminate the space wasted in the cabling space and to reduce the cost of cabling by deleting the connection cable between the input and output sharing device and the PC server to share the network source and multiple user interface devices The present invention provides a hot swappable cell server as a server system.

It is still another object of the present invention to provide a hot swap type cell server that can maintain a defined small size despite the expansion of a PC server server system sharing a network source with a plurality of user interface devices.

Another object of the present invention is to provide a hot-swap cell server that is easy to maintain and manage a failed PC server.
