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.
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 an External
Power Supply (EPS).
