1.
2x 10 GBit/s DAC cables
2x EAP773 PoE
1x 2.5 Gbit/s copper
2.
Fan did spin up and down already at:
PoE Power Used
24.60W / 200.00W
3.
I feel previously the fans stayed low, now they spin up every few minutes and then spin down again to previous levels.
4/5
No other changes. I will rollback later this week and let you know if that changed the fan noise.

Hi @Acorny
Thanks for your information.
We tested locally, and the fan noise is the same as before.
If convenient, please use a noise measurement app to test the noise level when the fan spins up and down.
In the meantime, we will test more locally with a similar installation.
