The maximum power to a powered device in a PoE+ system is ___.

Explanation:
In PoE+, the system defines both how much power the source (PSE) can push out and how much a powered device (PD) can actually receive. The power sourcing equipment can supply up to 30 W per port, but the powered device itself is limited to 25.5 W. The difference accounts for losses in the cable and the PD’s own power conversion circuitry, so the maximum power a PD can use is 25.5 W. The other numbers refer to the source capability or exceed what the standard allows for the PD.
