RB5009 Passive PoE doesn't support 24V devices (lazysoci.al)

Annoyingly, the RB5009 doesn't have a voltage regulator on its PoE-out ports. So it outputs ~48V, but other Mikrotik devices that support PoE-in only support ranges like 20-34V.

There is a solution! And I wanted to share it with you guys as my first post :)

48V-to-24V in-line convertor: https://www.aliexpress.com/w/wholesale-poe-Converter-48V-to-24V.html

This will convert the output from the RB5009 to 24V. Tested with PoE-out on RB5009UPr+S+ and PoE-in on CSS106-5G-1S.

The RB5009 is a fantastic device.

It is a per-port convertor. In my case, I want to power another switch by the RB5009. The other switch being the CSS106-5G-1S.

So I have RB5009:eth7, connected to CSS106:eth1. I'm expecting power output from the RB5009 to power CSS106, however by default the RB5009 outputs 48V and so is incompatible.

The convertor male end plugs into the RB5009, and then the other device plugs into the female part of the convertor. It then in-line converts 48V to 24V.

Ah, the search results for me were not related to PoE, but with a different search I see what you mean now.
