Can I connect PSU + POE at the same time, ccr1009?
PSU 220v
POE 27,8v
Check this old post out.
Yes. I accidentally did this on some kit I’m testing some stuff on.
Thank you very much for the answers. I sent e-mail to mikrotik support, and they replied:
please,
Can I power on ccr1009
in ac 220v together POE 27.8v? my batteries are POE.
I’m afraid to connect the two together.
Hello,
Yes, you can, many people use such a setup for redundancy.
Internally the PCB works at 24V and will choose the voltage that is higher, in your case priority will be on the PoE input.
