Hello,
I have a project using an Arduino Mega 2560 together with an Ethernet Shield.
I know that the Ethernet Shield itself is not PoE-capable, so I also bought a PoE Splitter / Passive Injector:
However, when I connect the PoE cable, there are still no signs of life from the Arduino.
Is there any setting that needs to be enabled, or is there something else I need to do to get this setup working?
Thanks in advance for your help.
Welcome to the forum
Exactly how are you connecting it and where are you connecting it ? What voltage is the POE cable outputting ?
I have an POE Injektor feeding the Patch Cable. The Patchcable is then connected to the POE Splitter which has one Cable connected to the Arduino and one to the Ethernet shield.
It was about 0.07 v
No matter how or where you connect it the Arduino is not going to work at that voltage. Do you mean 7V ?
No, it was 0.07.
Could it be that the PoE injector was not delivering the required power?
According to the instructions, if the PoE LED on the injector does not light up (which was the case) then the connected device is either not PoE-enabled or not compatible with the 802.3af/at standard.
The POE injector is certainly not delivering the required voltage.
I know little or nothing about POE but a quick search reveals that the normal POE voltage could be as much as 50V which would damage the Arduino if fed directly to it
Disconnect everything and measure the POE voltage
There are 3 Diffrent Types of POE
There is POE with about 15 W
POE+ with about 30W
And POE++ with about 60W
Yeah i will swap the POE Injektor and try again.
It is not the wattage that is the worry, it is the voltage
I am sure that you are bored with me asking but

ONE LAST TIME
To the POE Splitter
I give up
