PSE (Power Sourcing Equipment) is a device (switch,
or hub for instance) that provides power in a PoE setup.
Maximum allowed continuous output power per such
device in IEEE 802.3af is 15.4W, in IEEE 802.3at is 30W,
and in IEEE 802.3bt is 60~95W.
Note
PD (Powered Device) is a PoE-enabled terminal, such
as PoE IP phone, PoE IP camera, PoE wireless access
point or other, that consumes power from PSE.
