DSLRKIT USB Type C 5V 2.4A Active PoE Splitter Power Over Ethernet 802.3af 100 Mps

Vorweg: Ich habe bereits etliche PoE Splitter dieser Firma im Einsatz, jedoch bisher nur die Gigabit-Variante, die durchweg ordentlich funktioniert. Da für meinen aktuellen Anwendungsfall 100 Mbps (wahrscheinlich sogar 10) ausreichen, habe ich zur günstigeren Variante gegriffen.
Großer Fehler: Der Splitter liefert versorgt den Raspi 4B zwar mit Strom, aber nicht mit Netzwerk. An den anderen DSLRKIT PoE-Splittern gibt es keine Probleme, ebensowenig beim Betrieb am selben Kabel, aber mit seperater Stromeinspeisung. Ergo: Es liegt am Splitter. Und der geht zurück an Amazon.

P.S.: Habe hier in den Kommentaren einige Beiträge gelesen, dass der Splitter wohl die sog. "Speed Autonegotiation" (vgl. IEEE Standard 802.3-1998) nicht korrekt umsetzt und theoretisch funktionieren kann, wenn man am Switch den Port manuell auf 100 MBit umstellt. Das schränkt die Flexibilität für den Einsatz aber zu stark ein um die geringe Preisdifferenz zum Gigabit Modell zu rechtfertigen.

slow speed, breaks auto negotiation and limited to 100Mbit/s

I got 2 of this.

It only work with 100Mbit/s or lower, so if you got the Raspberry pi 4 for the 1 Gbit port it will only get 1/10 th of the speed.

this POE splitter breaks Autonegotiation (IEEE 802.3), so you need to manual set 100Mbit/s on switch or device for it work.

I was unable til get more then 4 Mbyte/s.

Stay away

Hooked this up to a raspberry pi 4 and while the splitter provided power, the ethernet cable didn't work. Returned for replacement. I'll update this review once the replacement arrives.

Update: Does not work with Raspberry Pi 4! I could get it to work, sort of, if I configured the port speed my managed switch. I changed it from auto-negotiate to any fixed speed, applied the change, and then set it back to auto-negotiate. However, if the cable is pulled or power is lost, you have to go thru the whole process again. Unacceptable. Really a deal-breaker if you have an unmanaged switch. Sending it back. Ordered the more expensive solution, the official Pi POE hat.

Pi 4 works fine with standard cat 5 cable and official Pi 4 power supply.

I wanted to like this as it was exactly what I need to power my Pi4 using POE.
However it has a number of faults.
It gets very hot! Laser thermometer is showing the outside of the case as 120 degrees F.
That is too hot and it is wasting power as well.
Then probably the worst part is that the Ethernet cable does NOT work. Only 4 of the pins are wired up as you can see in my picture so even if the cable worked you would only get a max of 100Mbps and will never get Gigabit speeds.
I will seek a refund for the two I bought as they do not work as advertised.
