One local power management unit is connected to a plurality of power distribution units through a peripheral communication interface and connected to the remote management system through an IP network. The local power management unit is configured to collect and analyze the operational data or power consumption information of the connected power distribution units through the peripheral communication interface and transmitted the processed data or information to the remote management system through the IP network. Hence, the workload of the remote management system is alleviated, the network cabling is saved, and the processing time of the polling operation carried out by the remote management system is shortened. ## Claims ### Claim 1 A local power management unit connected to a remote management system for regulating a plurality of power distribution units under the administration of the remote management system, comprising: an internal communication bus configured to connect to a plurality of power distribution units and proceed to data communication with the plurality of power distribution units through a peripheral communication interface;
