Evaluate the power budget. In the case of a DC-powered chassis, evaluate the budget
for each zone. In this step, we check the required power against the maximum output
power of available power supply options.
NOTE:
The power for the cooling system comes from a different tap on
the power supply, reserved for the cooling system only. The cooling system
power requirement does not need to be deducted from the output power
budget of the power supply.
