After Upgrade of M4300-8x8f fans stop Working
After a firmware upgrade of M4300-8x8f from 12.0.2.17 to 12.0.7.12 all fans are not working:

I also have this issue after firmware upgrade.
Chassis fans not spinning, orange warning led
Hi team. thank you for your messages and the heads-up.
This is all normal, let me explain what is happening. After 12.0.7.12 (latest M4300 family software upgrade), the M4300-8X8F is shutting down its main fans when the ambiant temperature is under 25 degrees Celsius (77 Fahrenheit). As soon as the ambiant temperature gets warmer, fans will start again, as usual.
We made this change after a consistent demand from many customers and we ran regression testing during a long time to ensure all vital and environmental parameters (MTBF etc.) stay intact. Due to its small footprint, the M4300-8X8F gets installed in many noise sensitive locations, especially when in AV environments, and turning off main fans reduces the perceived noise (only the PSU keeps running its fan, but overall this is 23dB max).
Based on your feedback, and also per our plans, we will need to enhance the software presentation, as this is not an error, but intended behavior. We will make sure the GUI and the show commands in CLI reflect that.
I hope it clarifies@

Hi Laurent, thanks for the update.
Just to confirm, our temps are ~9-13 degrees higher on this device than the12x12 immediately below it:
8X8:
FAN Status 
Unit ID 1 2 3 4 5 6 7 8 Fan-1 Error Error Fan-2 Error Error Temperature Status Unit ID 1 2 3 4 5 6 7 8 MAC 54oC 54oC System 67oC 66oC Max Operating Temperature 88oC 88oC 12X12:
FAN Status 
Unit ID 1 2 3 4 5 6 7 8 Fan-1 OK OK Fan-2 OK OK Temperature Status Unit ID 1 2 3 4 5 6 7 8 MAC 45oC 43oC System 54oC 52oC Max Operating Temperature 83oC 83oC Hopefully this is within normal operating parameters
I wonder if it might have been a good idea to sort out the error status/leds at the same time as making this change?
Many thanks
Andy
Thank you, everything as expected. You are well below max parameters - and all components are well within their spec.
You are right, software will have to be "aware" as well as LED circuitry. These changes are not trivial, but this our goal to phase them in asap.
Keep the communication going on the Community forum, and thank you for the feedback!

Don't forget about the LED warning/error indication 8-)
Hi there
Update, this is going to be fixed (LED and Software GUI/CLI) in 12.0.7.15
12.0.7.15 is on its way, this is the next maintenance release for M4300 series switches
You should see it live on https://www.netgear.com/support/product/m4300.aspx in the Download section by next week
Thanks again for the feedback,
