This tutorial describes the connection of Unipi controllers using 802.3at PoE+ splitter. The splitter must be supplemented and powered by a PoE injector or any PoE switch. This connection is useful especially if you need to place the controller in locations lacking a conventional 110 / 230 V~ socket (ie. sensor stations). This tutorial will show you how to power the Unipi over Ethernet cable while retaining local network connectivity.

Using a single splitter to power multiple controllers is not recommended!
The calculations below are applicable for GSD-908HP PoE+ switch and IPOE-162S PoE+ splitter.
1) Maximum number of connected Unipi Neuron L403 controllers
Based on these calculations, we can safely use 4 PoE+ powered Neuron L403's
2) Maximum number of connected Unipi Patron S107
Based on these calculations, we can safely use 8 PoE+ powered Patron S107's
3) Various combinations of Unipi models
Based on these calculations, a single switch can power 1× Patron L207, 2× Patron M207 and 4× Patron S107
