In an embodiment of the invention, the machine room may be powered using three phases, and each cabinet may be powered using two of the phases. All cabinets are N +1 redundant, namely the cabinets have 2 inputs, and the input working states are respectively working states and backup states. The cabinet comprises a double-input power module and a power management module, wherein the power management module can acquire input voltage, current and power of a power supply, and can switch the input working state (working state or backup state) of the power supply, namely, different power supply phases are utilized for supplying power.

In some embodiments, as shown in fig. 2, the three-phase power supply room includes a three-phase power supply line (a phase, B phase, and C phase), and a room a, a room B, and a room C, each room has a certain number of cabinets, and all the cabinets are connected to the control center through network lines to transmit data and instructions.
The machine room A is characterized in that the power input of the cabinet is an A phase and a B phase, wherein the cabinet of the A phase in the working state is marked as AA1-AAx, and the cabinet of the B phase in the working state is marked as AB 1-ABm; similarly, the machine room B is characterized in that the power input of the cabinets is B phase and C phase, wherein the cabinets with the B phase in the working state are marked as BB1-BBy, and the cabinets with the C phase in the working state are marked as BC 1-BCn; the machine room C is characterized in that the power input of the cabinets is C phase and A phase, wherein the cabinets with the C phase in the working state are marked as CC1-CCz, and the cabinets with the A phase in the working state are marked as CA 1-CAo.
The division of the machine room A, B, C can be divided based on different spaces, and when the machine room is deployed, it can be determined that the machine room is powered by a certain 2-phase, that is, the machine room A is provided with power supply circuits of the A-phase and the B-phase, and the machine room B, C is similar to the above; the virtual definition can also be performed, that is, all the cabinets input to the phase a and the phase B are cabinets in the machine room a, in this case, a certain three-phase power supply machine room is provided with 3-phase power supply plugs in the same number, and a certain cabinet is supplied with power by 2 phases in different paths.
