2. NOTICE! Risk of sensor damage. Only use PoE power sourcing equipment
(PSE) as described in "Choose the PoE power sourcing equipment (PSE) with
care" on page 15.
Connect the RJ-45 Ethernet connector of the sensor to the output of the PoE
injector.
3. Connect the PoE injector to a power supply.
4. Connect the input of the PoE injector to the non-PoE Ethernet switch.
5. Connect the controlling host to the non-PoE Ethernet switch.
6. Establish a connection between the power sensor and the network.
