Ensure sufficient nominal voltage

Ensure that any device supplying PoE (i.e. Power Sourcing Equipment (PSE)) to a consuming device (“Powered Device”, PD) is itself sufficiently powered, with a stable supply of at least 10.8 V dc.

Ensure that any device supplying PoE (i.e. Power Sourcing Equipment (PSE)) to a consuming device (“Powered Device”, PD) provides a nominal supply voltage to the PD device in the range of 44 V to 57 V dc.
