Notes
Maximum power rating and maximum heat dissipation are the worst-case
theoretical maximum numbers provided for planning the infrastructure
with fully loaded PoE (if equipped), 100% traffic, all ports plugged in, and all
modules populated.
PoE power is the power supplied by the internal power supply. It is
dependent on the type and quantity of power supplies.
