What advantage does PoE auto mode provide versus static mode when an AP is connected to a PoE switch port?

PoE auto mode, also known as negotiation or detection mode, is crucial because it allows the Power Sourcing Equipment (PSE), like a PoE switch, to detect if a connected device is a Powered Device (PD) and determine its power requirements. This prevents damage to non-PoE devices by not applying power unnecessarily. If the device is a PD, the switch then supplies the appropriate power. In contrast, a static mode would imply a fixed power delivery without this detection, which is not how standard PoE operates. Power policing is a separate feature for managing power consumption limits, not directly tied to auto vs. static mode. The default level is used only after detection, not as a primary advantage of auto mode itself. While some PoE standards can use all four pairs, this is a capability of the standard, not a specific advantage of auto mode over a hypothetical static mode.
