The disclosure provides a rack, including nodes and power supplies, and a power controlling method thereof, including the following steps. Power information of each node is collected to calculate a total power consumption value of the nodes. A power supply enabling demand is calculated according to the total power consumption value and a maximum power supply value of the power supply. State information of each of the power supplies is read to obtain a first sequence of the power supplies. According to the power supply enabling demand and the first sequence, two of the power supplies are enabled and set as a master power supply and a secondary power supply, and the rest of the power supplies are disabled. While the master power supply provides a work voltage to the nodes, the secondary power supply does not supply the work voltage to the nodes.

Rack and power controlling method thereof

A power control method of a rack having a plurality of nodes includes the following steps. Power information of each node is received. A total power consumption value of the plurality of nodes according to the power information is calculated. A number of power supply units to be turned on according to the total power consumption value and a maximum supplied power value of a single power supply unit is calculated. At least one primary power supply unit and at least one secondary power supply unit in pairs according to the number of power supply units to be turned on is started. The at least one primary power supply unit provides a duty voltage to the plurality of nodes, and the at least one secondary power supply unit does not provide the duty voltage to the plurality of nodes.

Rack and power control method thereof

A rack server includes multiple power supply backplanes and multiple Fan Controller Boards (FCBs). The power supply backplanes each have a connection unit. The connection unit has multiple connection terminals. One of the connection terminals is coupled to a ground terminal. Positions of the connection terminals of the connection units coupled to the ground terminal are different from each other. The FCBs are coupled to one of the corresponding power supply backplanes respectively. The FCBs each include an addressing circuit and a microcontroller. The addressing circuit is coupled to the connection terminals of the corresponding connection unit, and is used to generate an address signal by detecting and according to a coupling relationship between the connection terminals and the ground terminal. The microcontroller is coupled to the addressing circuit, and is used to receive the address signal, so as to generate corresponding address information.
