Networking systems and methods of assembly are described that provide a modular system that includes a main networking box and a detachable module. The main networking box and the detachable module are configured to be connected to each other on a datacenter rack via board-to-board connectors to provide the desired connections to the network, but can also be unlocked and detached from each other, such as to allow the main networking box to be replaced. In this way, the main networking box can be replaced in the field to provide a repair, or the detachable module can be replaced to provide a different connection type, without requiring the other component and/or its connections to be disturbed.
