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.
Table 28 on page 272 lists the power supplies, their maximum output power, and
unused power (or a power deficit) for MX480 AC
the power supplies, their maximum output power, and unused power (or a power
deficit) for MX480 DC chassis. See
on page 276 and "DC Power Supply Electrical Specifications for the MX480 Router"
on page 280 for more information about the MX480 power supply electrical
specifications.
