City Hall labels a closet diagram with “endpoint PSE” next to the access-layer switch feeding APs. What does endpoint PSE mean in this context?
Select an answer to reveal the explanation.
Short Explanation
Endpoint PSE is the friendly way of saying the switch is the power plant. Power starts at the switch port, rides the cable, and feeds the AP. Midspan is the other flavor—an injector in the middle.
Full Explanation
Endpoint power sourcing equipment integrates PoE in the Ethernet switch so the switch port itself supplies power to the AP. That contrasts with midspan PSE devices that insert power along the cable path between a non-PoE switch and the AP. Correct labeling helps municipal technicians match spare parts and troubleshooting steps to the closet design.
