The invention concerns a network equipment for connection to a local network and a method for monitoring the start up of a such an equipment. The input current limiting circuit includes an input current sensing circuit and a feedback compensation circuit, for limiting current of an input power signal of the driving device to a predetermined range. The architecture includes interfaces for components and designers to communicate. The flow of feed to one of the reaction zones is periodically stopped to allow sequential on-stream hydrogenative regeneration of the catalysts within the reaction zones. The oxides are supported on inert porous inorganic oxides, preferably alumina.
