New Summit x440-g2-24p-10ge4 when powered on the FAN 4 runs at a constant 15000RPM

[Marcel2]

I got 2 new New Summit x440-g2-24p-10ge4 Switches

1st one, when powered on the FAN 4 runs at a constant 15000RPMThe rest of the Fans, are quiet at 2100RPM, while nothing is plugged in.

Then the second one runs normally with normal fan speed but as soon as I plug one POE device into it the Temp goes up to 91C and fans refs up to over 4000 - 5000 RPM

Why will this happen?

Hi Marcel,
I was talking about your issue with a colleague and we think it would be best if you can open a ticket with GTAC on this. If you do, please share the case number with me here.
