Hi all. I have been running a CRS312-4C+8XG-RM for the last week and it has been great, but the package was missing rack ears, so the seller requested I send it back and I ordered a new one. I just got it installed today and it is way louder then the previous switch.
One thing I noticed is that the fans are running at 8k RPM while the CPU is still cool. https://imgbox.com/Nau3aidX
I have upgraded the Firmware to the latest version 6.49.7.
Any ideas why the fans on this would be running so fast? I cant seem to find a way to slow them down.
