Maximum power is the sum of the worse case power consumption of every subsystem in the box, and should
be used to size worse case power consumption. Typical power consumption numbers are what HP engineers
have measured running power intensive applications. These are generally lower than maximum power
numbers due to the fact that getting all of the subsystems in the box to simultaneously draw maximum power
for long durations is uncommon.
