Please help me understand what the problem is. I bought a new router L009UiGS-2HaxD-IN.
I connect 48V power supply to PoE in L009UiGS-2HaxD-IN in Ethernet01.
I enable “PoE Out force on” in the settings.
I connect another device to the Ethernet port 08 PoE Out: hAPac (RB962UiGS-5HacT2HnT) or POE Splitter 48V to 12V.
The red indicator on the PoE Out port lights up, but no power is supplied.
For the test I tried the opposite:
PoE 48V => PoE in RB962UiGS, PoE Out => L009UiGS – everything works.
Am I missing something or did they send me a faulty router?
The L009 is reknown for having iffy (to say the least) PoE support, both in and out.
See: http://forum.mikrotik.com/t/l009-dont-like-it/180693/18
And: http://forum.mikrotik.com/t/l009uigs-2haxd-in-no-passthrough-poe-again/171563/1
It seems that “by design” the L009 PoE out ONLY works if the L009 Is powered by DC jack.
The possible solution (actually work around) in your case could be a plain 48V splitter to extract the power and feed It to the DC jack.
No comment on the utter stupidity of the design and on the lack of proper documentation.
Thank you very much for the information. I had grandiose plans for L009, but it turned out to be so helpless and let me down
Now I’ll go and carefully study the RB5009UG+S+IN in the hope that at least there are no such pitfalls.
It’s a pity, a great pity. I really wanted the router and Wi-Fi to be in one device.
So, it was designed like this, but I agree they should have put the asterisk on the specification sheet also. This is where I usually look, not the marketing text above it or the PDF.
And you just opened (surely unintentionally) a (small) can of worms.
The Gigabit splitter may (or may not) be mapped as Mode A or mode B or both modes.
The 48V power supply (or the injector) may be mapped as mode A or mode B or both modes if it is one of those that have an RJ45 as exit..
If we take a Mikrotik power supply like the: https://mikrotik.com/product/48v2a96w
even if it is not mentioned anywhere, it comes with a normal DC jack.
You need with it an injector like: https://mikrotik.com/product/RBGPOE
(which is mode B, which most if not all Mikrotik devices use, i.e. pins 4,5 +; pins7,8 -)
Otherwise you can get a pair of injector/splitters, making sure they are gigabit capable, as long as they are used in pairs it doesn’t matter if they are Mode A or Mode B or both.
The issues may rise if you use a power supply that directly outputs PoE on RJ45 in (say) mode A and the splitter is intended for mode B or viceversa or if you “mix” two different splitters/injectors..

Hi! Based on the description, the problem could be in several places.

Not really, as already explained the L009 is NOT providing PoE out if powered by PoE in, by design.
The general troubleshooting steps you listed which would otherwise be good ones are in this specific case unneeded.
