A.1 MDI Settings
The Medium-Dependent Interface (MDI or RJ45) serves as the data/power interface between Ethernet elements. As such,
it has two optional connection methods to carry the power. Named Alternative A & B, Table 1 details the two power feeding
alternatives.
Delivering power through an RJ45 connector's center tap ("Phantom Feeding") guarantees that bi-directional data flow is
maintained, regardless of a module's power status.
