description: The Si3474 is a single-chip PoE PSE controller managing
30

8 physical power delivery channels. Internally, it's structured
31
+
into two logical "Quads".
32
+
Quad 0 Manages physical channels ('ports' in datasheet) 0, 1, 2, 3
33
+
Quad 1 Manages physical channels ('ports' in datasheet) 4, 5, 6, 7.
