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 45 on page 176 lists the power supplies, their maximum output power, and unused power (or a
power deficit) for an AC-powered services gateway. Table 46 on page 176 lists the power supplies, their
maximum output power, and unused power (or a power deficit) for an DC-powered services gateway.
