After boot the PoE Switch (561839 from intellinet) kicks the Cube. This does not happen with Mikrotik’s supplied PSU.
Said switch supports 802.3at, so its really not a weak one.
I assume there is a power surge and Mikrotik saved on local capacitance (maybe because of space constraints). Unfortunately while conventional AC/DV power converters are very forgiving with power surges, PoE switches are not.
Anything official?
