In embodiments of the present invention, which is located in server, and server here can be blade server,
Perhaps multi node server or the rack server with backboard etc..It should be understood that blade/multi node server and common
Do not include that the rack server of backboard has very big difference on morphosis, rack server usually by mainboard plus expansion card,
Expansion board composition, and blade/multi node server has backboard, connects the machine frames component such as Servers-all node and frame fan.
Usually shared power supply, common fan, power board and management board etc., can subtract between each node of blade/multi node server
Lack interconnection traces and convenient for management, each node is both independent device, interconnects, forms a whole further through backboard.
It should be understood that the embodiment of the present invention in backboard can for printed circuit board (Printed circuit board,
PCB), which is multi-layer board.In the prior art, backboard need to only provide single power supply, therefore existing backboard can use single side
PCB version, or multi-layer PCB board can also be used, but each layer also only provides identical voltage in multi-layer PCB.And the present invention is real
It applies in example, backboard uses the PCB version of multilayer, can input or export different voltages between different layers, i.e., in the multi-layer PCB board not
Same layer, to the different electrical power plane that should be used as backboard.
In embodiments of the present invention, which can externally have multiple-way supply input, pass through the power supply terminal of server
It is connected with cabinet (Power Distribution Unit, PDU)；First group of power supply in the server internal, backboard 100
Plane can be used as the supply input plane of the server, specifically, each electricity in first group of power plane of the backboard 100

End or the end B can be used as the power supply terminal of the server, be connected with PDU, to obtain one in the multiple power supplies of PDU offer
Road power supply obtains the first electricity for example, the first power supply in the multiple power supplies that the first power plane V1 110 is provided with PDU is connected
Pressure.Similarly, when first group of power plane of the backboard 100 includes multiple power planes, each power plane is similar to
V1 110, i.e., the power supply all the way in multiple power supplies that each power plane can be provided with PDU are connected the corresponding voltage of acquisition,
And different power planes can be connected with identical power supply, alternatively, different power planes can also be from different power supply phases
Even, so that the available different voltage of multiple power planes in first group of power plane.
Optionally, as shown in Fig. 2, the first power plane V1 110 of the backboard 100 can also be opened by being combined multiselect one
It closes 130 to be connected with the first power supply in multiple power supplies, i.e., each power plane in the first of the backboard 100 group power plane is equal
It is switched including a combining multiselect one, obtains the electricity of power supply offer for being connected with any power supply all the way in multiple power supplies
Pressure allows each power plane to obtain a kind of voltage, i.e., at least one electricity in first group of power plane in the server
Source plane can provide the voltage of identical or different type.
For example, the V1 110 passes through combining one switch 130 of multiselect, i.e. the combining multiselect one by taking the V1 110 in Fig. 2 as an example
Power supply terminal of the C-terminal or the end D of switch 130 as server, is connected with PDU, obtains the first power supply in the multiple power supplies of PDU
The first voltage of offer.Similarly, each power plane of first group of power plane of the backboard 100 can be more by being combined
A switch is selected to be connected with the power supply all the way in multiple power supplies, in this way, realizing in backboard by the switch of combining multiselect one in backboard
Flexible switching of each supply input power plane between multiple power supplies so that the power supply output plane of backboard can be with
Corresponding multiple voltage is provided, there can be identical or different voltage in the multiple voltage, in this way, node in the server,
After the components such as power board, management board, fan are connected with the power supply output voltage plane of backboard, according to needed for different machine frame components
Different voltages, the different output voltage plane power supply of flexible choice, further promote the reliability of server power supply.
For example, with any one power plane, i.e. V1 110 in first group of power plane, with combining one switch 130 of multiselect
For, as shown in Fig. 2, V1 110 can be connected acquisition by being combined one switch 130 of multiselect with the first power supply in multiple power supplies
First voltage, the multiple power supplies may include multiple voltage, which can be direct current, or alternating current, example
Such as, which can specifically include 220Vac the exchange perhaps high voltage direct current such as 240Vdc/380Vdc or conventional telecommunications
Computer room -48V direct current etc., by being combined one switch 130 of multiselect, V1 100 can flexibly switch between the multiple power sources.
In addition, can also pass through when first power failure of the V1 110 by combining one switch 130 of multiselect connection
130 moment of one switch of combining multiselect switches to other power supplys, it is ensured that entire server power supply is normal.For example, when the first power supply
When breaking down, it can be connected by being combined one switch 130 of multiselect and switching to V1 110 with second source, the second source is same
Sample can provide first voltage, so that the server continues to work normally；Or the second source can also provide other voltages,
Then the voltage on V1 110 also becomes other voltages that the second source provides from first voltage, replaces former the by the other voltages
One voltage continues as server power supply.
Therefore, V1 110 can be connected by being combined one switch 130 of multiselect with any one voltage in multiple power supplies, be obtained
Corresponding voltage is obtained, avoids backboard in the prior art that from can only providing the voltage plane of single voltage type, and in the electricity of connection
It when the failure of source, switches at any time, improves server power supply reliability.

Same power plane exports the identical voltage.For example, one power supply from first group of power plane of the PSU1 in the server is flat
Electricity is taken on face, inputs 48V direct current；PSU2 in the server in first group of power plane in another power plane from taking
Electricity, input 12V DC electricity；By the conversion of PSU1 and PSU2, PSU1 and PSU2 are converted to 10V direct current, then the PSU1
The 10V direct current can be exported to the same power plane of second group of power plane with PSU2, alternatively, can also be respectively to two
A different power plane exports the 10V direct current, and the embodiment of the present invention is not limited to this.
