Description
technical field [0001] The invention relates to communication technology, in particular to a control system for hot swapping of functional modules of rack-type equipment with centralized power supply in the field of communication. Background technique [0002] In modern communication equipment, rack-mounted / non-isolated low-voltage backplane-powered equipment is becoming more and more common. The functional modules of this type of equipment are usually powered by the equipment. The biggest advantage is that the power supply part can save isolated DC / DC (DC- DC) converter cost, functional modules can be flexibly configured according to user needs. At the same time, for the convenience of use, these functional modules can be hot-swapped on the rack (swappable functional modules with power on). One of the technical problems to be solved for the functional modules to support hot swapping is to prevent strong interference to the power system of the whole device during the pluggi...
