The power supplies can work together in Redundant Mode, in which each power supply operates at
approximately 50 percent of its capacity, no greater than 60 percent and no less than 40 percent. If one power
supply fails, the other power supply can provide power for the entire system on its own. This is the default
and recommended mode.
