- 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+)
