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% trac, 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).
370 W of PoE+ power is available using the internal default
power supply.
