Problems solved by technology

[0003] However, at this time, the number of PSUs normally supplying power is reduced, and the total power provided is also reduced.
If the power consumption of the network equipment exceeds the total power limit of the remaining normal PSUs, the network equipment may be shut down abnormally or cause other failures due to insufficient power output, which will affect the normal operation of the entire network.

Embodiment Construction

[0013] see figure 1 A preferred embodiment of the present invention provides a network device 100, which may be a server, a network switch, etc., and includes a plurality of power supply units (power supply unit, PSU) 11, a central processing unit (central processing unit, CPU) ) 12 , north bridge chip 13 , baseboard management controller (baseboard management controller, BMC) 14 , south bridge chip 15 and power development board (power development board, PDB) 16 . The CPU 12 , north bridge chip 13 , south bridge chip 15 , BMC 14 and PDB 16 are electrically connected in sequence.

[0014] The multiple PSUs 11 are all connected to the PDB 16 for supplying power to various components (such as the CPU 12 ) in the network device 100 , and each PSU 11 has a rated power Pmax respectively.

[0015] The CPU 12 is used to control multiple components such as heat sinks and relays installed in the network device 100 to work normally. The CPU 12 has multiple operating frequencies, and e...

Abstract

The invention provides network equipment and a power consumption control method thereof. The network equipment comprises a plurality of power supply units, a central processing unit and a substrate management controller, wherein the power supply units supply power to the central processing unit, and each power supply unit is provided with a rated power; and the substrate management controller is used for detecting whether all the power supply units normally work or not, and when one or more of the power supply units are detected to be incapable of normally supplying power, the power consumption of the central processing unit is correspondingly regulated by the substrate management controller so as to be equal to the total power supplied by the remained power supply units for normally supplying power.

Description

technical field [0001] The invention relates to a network device and a power consumption control method thereof, in particular to a network device capable of automatically controlling power consumption and a power consumption control method thereof. Background technique [0002] With the growth of data traffic and the improvement of service quality requirements, high reliability has become one of the most important indicators of high-performance communication networks. In order to achieve higher reliability, existing network devices such as network switches and servers are generally equipped with multiple power supply units (power supply units, PSUs). When one or a part of PSUs fails, the remaining PSUs with normal performance can still maintain the power supply of the network equipment. [0003] However, at this time, the number of PSUs normally supplying power is reduced, and the total power provided is also reduced accordingly. If the power consumption of the network eq...
