Power over Ethernet (PoE) was developed to enable power (48 V DC) to be delivered to an IP device via its data cable where a separate power supply may not be available.
PoE simplifies and reduces installation costs as only one cable needs to be installed, supplying both data and power.
However, remembering the details of the IEEE Standard PoE Pin/Data Assignment can be difficult.
