On a municipal closet sketch, an AP hangs from a PoE injector that sits between a non-PoE switch and the AP. How should those roles be labeled?
Select an answer to reveal the explanation.
Short Explanation
Picture the food chain: AP eats (PD), injector cooks in the middle (midspan PSE), plain switch just passes data. Label it that way on the closet sketch and future techs will thank you.
Full Explanation
In a midspan injector topology the AP is the powered device (PD), the injector is the midspan PSE that adds power, and a non-PoE switch provides data only on that path. Endpoint PSE would describe a PoE switch sourcing power directly. Correct inventory labels prevent mis-ordering spare injectors or blaming the wrong device when an AP will not power on.
