A communication device and its power management method

Abstract

Embodiments of the present invention disclose a communication device and a power supply management method thereof, and relates to the field of communications, so that the use efficiency of a power supply module of the device can be more effectively improved, and power consumption of the device is reduced. A management processor of a control module in the communication device is used for obtaining the maximum power consumption of the control module and the number of interfaces actually used of each service function module, and obtaining maximum power consumption of each service function module according to the number of interfaces of each service function module and a power consumption mapping array; according to the maximum power consumption of the control module and the maximum power consumption of each service function module, the power consumption of a fan module is determined; according to the maximum power consumption of the control module, the maximum power consumption of each service function module, and the power consumption of the fan module, the total power consumption is determined; and according to the total power consumption, the use number of the most appropriate power supply module is determined. The communication device and the power management method disclosed by the embodiments of the present invention are applied to accurate power management of communication devices.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular to a communication device and a power management method thereof. Background technique [0002] With the widespread popularization of Internet information technology and applications, there is a great demand for data flow, which promotes the continuous development of high-speed and large-capacity technology for data communication equipment. In the current user network construction, 10G port equipment has already The access layer is used, and the aggregation layer and core layer devices are basically only equipped with 40G and 100G ports. Large-capacity data communication equipment supporting high-density and high-speed ports, its business function modules (LPU (English full name: Line Processing Unit, Chinese: business module), SFU (English full name: Switch Fabric Unit, Chinese: switching module) and other Functional modules such as fan modules consume a lot of p...

AI Technical Summary

Problems solved by technology

[0004] At present, the power management of large-capacity data communication equipment in the industry mainly focuses on monitoring whether its functions / performances are normal, such as input overvoltage, undervoltage, output overvoltage, undervoltage, overcurrent protection, and overtemperature alarm of the power supply module. , whether the cooling fan is normal, etc., this cannot effectively improve the efficiency of the power supply module to reduce power consumption
