Hi all

 

My SX3206HPP spins up the fans audibly as soon as I connect a 10GBase-T device to it. Since the switch is in the office this is rather annoying. Limiting the port speed to 1000M will resolve this (2.5G/5G still cause the fan to spin). The fan is spinning even if the device/link is pretty idle.

 

Is this expected behaviour and is there anything I can do to turn off the fan if not strictly needed (i.e. the device gets hot)

 

As the CPU usage is 2.6% average / 4% maximum, I'd expect the fan not being required.

 

Thanks in advance
