RB750UP PoE randomly turning on/off

Hi there.. I hope you can help me

I’m experiencing a quite strange problem with my RB750UP. The PoE Output keeps randomly turning on/off (no matter if a device is connected or not) - I tried it with every Port on forced on and automatic mode. Could it be a hardware problem, because it works just fine sometimes..?
My current Firmware is 6.7 and all Packages are enabled..

Thanks in advance,

I have some750 UP, but have never seen your problem. Do you yse original power? If so, it seems like a HW problem (might be a poe client having a strange problem)

I suggest to upgrade to latest RouterOS v6.8rc version and check whether it works ok. If not, then we need to know an output from

    /interface ethernet poe monitor [find]

It will show a reason why port is turned off in forced-on mode.
