Abstract
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.
