3 PSE Power Interface (PSE PI) Documentation
6 The Power Sourcing Equipment Power Interface (PSE PI) plays a pivotal role in
7 the architecture of Power over Ethernet (PoE) systems. It is essentially a
8 blueprint that outlines how one or multiple power sources are connected to the
9 eight-pin modular jack, commonly known as the Ethernet RJ45 port. This
10 connection scheme is crucial for enabling the delivery of power alongside data
11 over Ethernet cables.
