5 port gigabit switch powered over POE via one of the cables

<< < (12/12)

peter-h:
It is working perfectly now. Thank you for all your help :)

The Tenda PoE30G-AT is driving the TP-Link TL-PoE10R splitter.

The forum has changed to HTML; how do I set it so it drops formatting?

peter-h:
This is rather interesting. From above

* Mode A: uses two twisted pairs for power, pins 1, 2, 3, 6

That should mean that my Linksys POE switch should deliver power over the first two pairs (of the cable which has only those connected) and there is no need for the Tenda injector.


Linksys data sheet: IEEE 802.3, 802.3u, 802.3x, 802.3ab, 802.3az, 802.3af, and 802.3at (PoE+)

So I tried it, and it works! The TP-Link TL-PoE10R splitter is now powered from the other end of the system!

Nice!  I just wish PoE router datasheets/manuals were explicit on the modes they support.

But.. does this mean you bought both the Tenda PoE30G-AT and the TP-Link TL-RP108GE for nothing? Can you get your money back?

peter-h:
Correct.

I will keep the Tenda injector; could be handy one day.

The RP108 is going back. The vendor is dragging their heels over the return though.
