Backhaul ports in Mikrotik CRS328-24P-4S+ Switch going off unexpectedly

Hi,

We note an unusual performance with our Mikrotik CRS328-24P-4S+ Switch. Our Ubiquiti rocket prism backhaul ports being powered by the switch unexpectedly go off. They only come back on when we power cycle the port. Please note we have upgraded the CRS switch to the latest stable firmware version: 6.47.7 and forced POE on, on the respective ports. Also note that the switch is being powered by 24V. What could be the problem? Is it power starvation? How can we solve this?

Thank you.
