Help!
sorry for my English
I have 2 RB433AH that were running for 6 months (24HPOW + Ups + POE + 20 meters Cat 5 FTP). The problem is that if it works poe 18 V, 24 V poe but does not work.
RouterOS I upgraded to 4.17, routerboot 2.29, 0 mini-pci, but even work only with 18V poe.

With PoE 24 V restarted constantly.



With 18 V poe apparently works well





options??

Will repair the filters, but I am a little concerned as they only have 6 months of use, I have RB433 running for over 2 years.

Gracias por tu ayuda mgutz2 y a los demas...
