210 Device Tree Configuration: Describing PSE PI Configurations
213 The necessity for a separate PSE PI node in the device tree is influenced by
215 descriptions of both simple and complex PSE PI configurations to illustrate
218 **Simple PSE PI Configuration:**
219 In a straightforward scenario, the PSE PI setup involves a direct, one-to-one
220 connection between a single PSE controller and an Ethernet port. This setup
223 configurations, detailing the PSE PI within the existing PSE controller's node
228 **Complex PSE PI Configuration:**
229 Contrastingly, a complex PSE PI setup may encompass multiple PSE controllers or
234 these instances, a dedicated PSE PI node becomes essential for accurately
236 interactions between different PSE controllers, the support for various PoE
242 For simple PSE setups, including PSE PI information in the PSE controller node

249 PSE PI Node: Essential Information
252 The PSE PI (Power Sourcing Equipment Power Interface) node in a device tree can
256 necessity and reasons why they might not be found within a PSE controller node:
264 - *PSE Controller Node:* Typically lacks details on physical pair usage,
272 - *PSE Controller Node:* Polarity management may exceed the standard
273 functionalities of PSE controllers.
275 3. **PSE Cells Association**
277 - *Description:* Details the association of PSE cells with Ethernet ports or
281 - *PSE Controller Node:* Controllers may not manage cell associations
290 - *PSE Controller Node:* Specific capabilities may depend on the overall PSE
291 PI design rather than the controller alone. Multiple PSE cells per PI
298 - *Necessity:* Provides extra safety and stability, complementing PSE
300 - *PSE Controller Node:* Some protections may be implemented via
