Abstract

A power supply control apparatus, where the power supply control apparatus is configured to control power supply to a cabinet in a data center is presented, where the power supply control apparatus includes a communications module configured to receive an instruction of a network management center, and a controllable switch configured to adjust a capacity of the controllable switch according to the instruction to perform power-on/power-off control on the cabinet. In various embodiments, a power supply control apparatus may receive an instruction of a network management center, and can adjust a capacity of a controllable switch according to the instruction, which enhances power distribution flexibility, and therefore, a workload of changing a switch and a power cable can be reduced, and an engineering related risk can be avoided.

First claim

What is claimed is:

1. A power supply control apparatus configured to control power supply to a cabinet in a data center, the power supply control apparatus comprising:
a communication module configured to receive an instruction from a network management center; and
a controllable switch coupled to the communication module, the controllable switch comprising a plurality of front-end switches, each front-end switch having a rated value, and the controllable switch is configured to:
use the instruction to select a front-end switch of the plurality of front-end switches based on the rated value of the front-end switch; and
selectively control the power supply to the cabinet responsive to providing the power supply to the front-end switch.

2. The power supply control apparatus of claim 1 , further comprising a monitoring module, the monitoring module being configured to monitor information about an inner electrical parameter of the cabinet, and the communication module is further configured to report the information monitored about the inner electrical parameter to the network management center.

3. The power supply control apparatus of claim 2 , wherein the inner electrical parameter comprises at least one or more of a current, a voltage, active power, reactive power, a quantity of electricity, a power factor, three-phase balance, or a waveform distortion rate.

4. The power supply control apparatus of claim 1 , wherein the power supply control apparatus is a power distribution cabinet, the power distribution cabinet being coupled to the cabinet using a cable and being configured to control a quantity of rated power supply current delivered to the cabinet using the front-end switch.

5. The power supply control apparatus of claim 1 , further comprising a collection module, the collection module being further configured to collect environment information of the cabinet, and the communication module being further configured to report the environment information to the network management center.

6. The power supply control apparatus of claim 5 , wherein the power supply control apparatus is a plug-in unit, the plug-in unit being configured to acquire power from an uninterruptible power supply (UPS) output power distribution cabinet by using a busbar.

7. The power supply control apparatus of claim 5 , wherein the environment information comprises at least one of temperature information, depth information, smoke information, or position information.

8. The power supply control apparatus of claim 1 , further comprising an auxiliary power source.

9. A method for controlling power supply to a cabinet in a data center, comprising:
receiving, with a communication module, an instruction from a network management center; and
selecting, with a controllable switch according to the instruction, a front-end switch of a plurality of front-end switches based on a rated value of a capacity of the front-end switch;
supplying power to the front-end switch in response to selecting the front-end switch of the plurality of front-end switches; and
selectively controlling power-on of the cabinet responsive to supplying the power to the front-end switch.

10. The method of claim 9 , further comprising:
monitoring information about an inner electrical parameter of the cabinet; and
reporting information about the inner electrical parameter to the network management center.

11. The method of claim 9 , further comprising:
collecting environment information of the cabinet; and
reporting the environment information to the network management center.
