PoE power
Notes Idle power is the actual power consumption of
the device with no ports connected.
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.
