Hi @mikrotik!
The TP-Link TL-POE10R Gigabit POE-Splitter doesn't work with your cAP ac (RBcAPGi-5acD2nD) on the ether2 port (same in both modes: auto/forced on).
❓ Does #MikroTik make a GIGABIT PoE splitter that's compatible with your special 24V flavour of PoE?
❓ Which GIGABIT PoE splitter is compatible with the cAP ac?
🧵 2/n i've found a #MacGyver #DIY solution to my #PoE problem; instead of using the PoE-out on ether2, i'm tapping into the PoE-in supply! 😱 No worries, it's long out of warranty - well, the 2 years of merchant warranty at least, not sure about #MikroTik. 😉
Also, this time, i'm using a DC-DC regulator with a very wide input range (up to 100V) and a FIXED 5V output, so i can switch to "proper" 57V PoE without frying downstream devices, again! 😅
It wörks! 👍
🧵 3/n while saturating both GbE ports during my iperf3 run, the wifi throughput broke down severely!
I can probably set up some kind of #QoS scheme that always prioritises wireless over wired.
And while i'm at it, i need to figure out how to use #WinBox over wired connections - currently, only wireless via MAC address wörks.
My #MikroTik cAP ac does have an IP address configured - i can ping it, but WinBox (v4) won't connect, unless i'm connecting wirelessly via MAC addr.
🧵 4/n i'm also quite fond of their thermal solution - #MikroTik (cAP ac) uses big bare pads and lots of through-plated vias to conduct heat to the other side of the PCB. 🤩👍
Covering the signal vias with solder mask (the green stuff) is called tenting - i think you could tent (fill-plating?) them with metal as well, but that's overkill and unnecessarily expensive - the additional silk screen print (the white stuff) is for extra insulation.
