A temporary city inspection trailer has a non-PoE switch but needs to power one indoor AP over Ethernet. What should the technician use, and how is that PSE role commonly classified?
Select an answer to reveal the explanation.
Short Explanation
No PoE switch? Slide an injector into the middle of the run—that midspan PSE adds power without replacing the whole switch. The AP still sits at the far end as the PD.
Full Explanation
When a switch lacks PoE, a midspan injector can add power on the Ethernet path to the AP. Injectors are commonly midspan PSEs, whereas PoE-capable switches act as endpoint PSEs. Technicians distinguish these roles so they select the right hardware for trailers and other non-PoE closets without unsafe improvisation.
