Hi,

is it possible to use PoE in parallel of the integrated PSU to have redundant power ?

Thank you,

Bobby

Yes, eth13 can be used to power this routerboard - you must use different voltage. If integrated power supply is 24v, use 12v for POE (don’t remember if internal psu is 12v or 24v).
The board will use the PSU with higher voltage and failback on other.

Interesting ! Do you know a compatible and compact poe injector ? I suppose we need up to 3A using 12V, but I didn’t see any voltage or max amperage in the technical details or the poe injector sold anywhere…

Thank you

Bobby
