PSE PI setup may encompass multiple PSE controllers or auxiliary circuits that collectively manage power delivery to one Ethernet port. Such configurations might support a range of PoE standards and require the capability to dynamically configure power delivery based on the operational mode (e.g., PoE2 versus PoE4) or specific requirements of connected devices. In these instances, a dedicated PSE PI node becomes essential for accurately documenting the system architecture. This node would serve to detail the interactions between different PSE controllers, the support for various PoE modes, and any additional logic required to coordinate power delivery across the network infrastructure. The old usage of "#pse-cells" is unsuficient as it carries only the PSE PI index information.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
