摘要： A line module for use in a network device includes a plurality of circuits; and a power module connected to the plurality of circuits, and to a first Power Distribution Unit (PDU) and a second PDU, wherein the first PDU and the second PDU provide power distribution by different feeds, wherein the power module is configured to initiate a shutdown procedure when one or more of i) a current drawn from any feed equals or exceeds a first current threshold, and ii) an aggregate current drawn from all feeds equal or exceeds a second current threshold.

摘要： A method for power management that includes: determining, by a network device, a maximum current rating of a first power distribution unit (PDU) driven by a first direct current (DC) power plant including multiple backup batteries; determining multiple power ratings for multiple line modules in the network device, where the multiple line modules are connected to a first feed from the first PDU and a second feed from a second PDU; calculating, by the network device, a maximum aggregate current for the multiple line modules based on the multiple power ratings and a shutdown voltage corresponding to the multiple backup batteries; and allocating, in response to the maximum aggregate current exceeding the maximum current rating, a first current threshold to a first line module and a second current threshold to a second line module.
