Power sourcing equipment
Encyclopedia
Power sourcing equipment refers to network devices (switches
or hubs for instance), that will provide power in a Power over Ethernet
(PoE) setup.
When the device is a switch, it's called an endspan. Otherwise, if it's an intermediary device between a non-PoE-capable switch and a PoE device, it's called a midspan.
