Introduction
The Raspberry Pi PoE HAT is a handy add-on board that powers the Raspberry Pi 3 Model B+ using an Ethernet cable. In addition, it has a 25mm fan that provides cooling to the Pi and its CPU.
In this guide, we will show you how to connect it to the Pi and a PoE-capable network router. Please note that the HAT will only work with PoE-capable network routers or switches, standard routers or switches will not work here
Step 1 The parts



-
The full list of parts required are the PoE HAT, Raspberry Pi 3B, 4 stand-offs, 8 screws, an ethernet cable, and a PoE-capable network router.
-
First let's inspect the PoE HAT and some notable parts of it. It has a mini 25mm fan attached to it, four holes to mount it to the Pi with screws and stand-offs, a 2x20 GPIO female header, and a 4 pin surface mount connector.
Step 2 Align stand-offs with Raspberry Pi

-
Now, carefully align the four stand-offs to the Raspberry Pi 3B+ as shown.
-
If you would like to add heat sinks to the Raspberry Pi, it will fit nicely even with the PoE HAT.
Step 3 Attach PoE Hat to Raspberry Pi

-
Next, carefully attach the PoE hat to the Raspberry Pi, and it should be aligned with the 2X20 GPIO header as well as aligned with the 2x2 header.
Step 4 Attach screws to stand-offs



-
Next, use a screwdriver to attach four screws to the stand-offs.
Step 5 Turn Pi over and attach screws to stand-offs



-
Flip the Raspberry Pi to the back.
-
Attach screws to the stand-offs on that side as well. This will keep it securely in place.
-
Insert microSD card into the microSD card slot.
Step 6 Connect an ethernet cable

-
If you would like to add peripherals such as a wireless keyboard to the Pi, attach it to the USB port now.
-
Finally, connect one end of the ethernet cable to the ethernet port on the Raspberry Pi 3B+.
-
Connect the other end of the ethernet cable to your PoE-capable network router.
-
When disconnecting the PoE HAT from the Raspberry Pi, pull the 4-pin surface mount pair connector off gently and evenly. Do not pull one end of the connector off before the other.
