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 and may be supplemented with the
use of a External Power Supply (EPS).
With AC input, the Max power consumption is 523W (370W for PoE)
