What is the minimum power supply requirements for a loaded dsp chassis, say 10 dsp's and 2 arc's? What is required to have redundancy within the chassis? At what number of cards does a dual 70 amp chassis not provide redundancy if this is a problem? Another related question, how many dsp's can be handled by an arc? With the new multi trunk dsp's the limit must be fairly high. Is there a realistic need for more than one in a chassis containing only single trunk dsp's?
