Abstract: A communications device is disclosed, the device includes a container, at least one power module, at least one temperature regulating module, and multiple boards. The container is configured to accommodate the at least one temperature regulating module and the multiple boards, and the container is further configured to accommodate a power bus layer. The power bus layer is connected to the at least one power module, the at least one temperature regulating module, and the multiple boards. The at least one power module is configured to supply power to the at least one temperature regulating module and the multiple boards by using the power bus layer. At least part of communication among the multiple boards, the at least one power module, and the at least one temperature regulating module is performed in a power line communications manner by using the power bus layer.
