Unexpectable port down

[DimitrisNik]

Hi all,

In the last days i'm facing unexpectable port down and the poe devices reboots.

WS-8-150-AC
Firmware Version: 1.5.12
(updated before a week)
Board Rev: F

Port 1: Cambium ePMP 24V 0.75A
Port 2: Cambium ePMP 48V 0.75A
Port 3: Cambium ePMP 48V 0.75A

In all cases I found that the devices had lost power and rebooted. For long time i had no problems and everything worked without issues.
What do you suggest? Downgrade the firmware?

Here is my logs:

Also i found that I have similar problems in another Netonix that I put the latest firmware.

WS-6-MINI
Firmware Version: 1.5.12
(updated on Mar 23)
Board Rev: F

Port 3: Cambium ePMP 24V 0.75A
Port 4: Cambium ePMP 24V 0.75A
Port 5: Cambium ePMP 48V 0.75A

Do you suggest to downgrade firmware to 1.5.8? Is that possible?
