1. Calculate the power requirements (usage) using the values in
Router" on page 189

DPC - Slot 3
Zone 0 total output power
Zone 1 total output power
Zone 0 total output power (excluding cooling system)
Zone 1 total output power (excluding cooling system)
2. 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.
