1This amendment to the IEEE 802.3 standard was approved on June 12, 2003, and defined how to provide PoE to 10BaseT (Ethernet), 100BaseT (Fast Ethernet), and 1000BaseT (Gigabit Ethernet) devices802.3af
2either requests or draws power from the power-sourcing equipment Must be capable of accepting up to 57 volts from either the data lines or the unused pairs of the Ethernet cableThe powered device (PD)
3searches for powered devices by using a direct current (DC) detection signal  After a PoE-compliant device is identified, it will provide power to that deviceThe power-sourcing equipment (PSE)
4What happens If a device does not respond to the detection signature that the PSE sends:PSE will withhold power to avoid power damaging
5Provides power and Ethernet data signals from the same device. They are typically PoE-enabled Ethernet switchesEndpoint PSE
6Acts as a pass-through device, adding power to an Ethernet segment. It is placed between an Ethernet source (such as an Ethernet switch) and a PDmidspan PSE
7The Power-Sourcing Equipment (PSE) must have athis to carry the current to the Powered Device (PD)Medium Dependent Interface (MDI)
8If we want to deply an AP to switch and get power, what are the 3 PoE options:1) AP to SW with inline power
2) AP --inline power patch panel--SW without inline power
3) AP --- Power injector ----SW without inline power
9At maximum power for a PD, the PSE must be capable of providing:15.4 W or 30 W (if it is PoE+)
