This Power over Ethernet HAT is a handy accessory for the Raspberry Pi computer.
It can be used only with the Raspberry Pi 3B+.
The PoE HAT allows you to power your Raspberry Pi from Power over Ethernet-enabled networks; for this product to be used, the network it is connected to needs to have power-sourcing equipment installed.
Sometimes a small incompatibility can be noticed between the switch, the PoE injector ( 802.3af, 10/100Mbit) and the network chip of the Pi 3B+.
In this case, the network speed should first be set manually to 100 MBit (full duplex).
Under Raspbian the ethtool is used for this purpose. The command is sudo ethtool -s eth0 speed 100 duplex full. The Pi 3B+ should then be able to establish a wired network connection.
