After a firmware upgrade of M4300-8x8f from 12.0.2.17 to 12.0.7.12 all fans are not working: FAN Status Unit ID 1 2 3 4 5 6 7 8 Fan-1 Error Error Fan-2 Error Error When the device is restarted, the fans work for 20 seconds, then they stop The Fan-LED on the Frontpanel is grren the first 20 seconds, then it goes to orange There was no Problem with the old Firmware. Is this a known Problem? Is there a fix for it?

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, Regards,

Hi Laurent, You replied to my original support case where I reported this issue.. #41303601 I have upgraded 5 of our 8X8F switches today to 12.0.7.15, they all have ORANGE led and 'fan stopped' At what temperature should the fans kick in? Can you please make this an optional setting, I understand the want to have a quiet switch if it's on your desk etc. When they are used in a comms room, I would prefer them to be cooling themselves constantly. Is there a way we can manually change the temperature range so the fans will kick start? See attachment for current temps!Thanks

Hi,In current firmware we have fixed the software. Bith GUI and CLI show correct OFF status when fans are shut down because ambiant temp is under 25C and the switch internal components are within spec.Remains the amber light on the front. The LED amber color will be fixed in subsequent firmware. I would advise you upgrade to the latest FW if you can bear with the amber FAN light. Regards,

Hi LaurentMa , Thanks for the swift reply. Do you know if the firmware guys will be adding the option to force the fan on? I don't like seeing these switches at 59 degrees when a 48 port PoE switch a few U beneath it is at 31 degrees.

Thank you for your message. I hear you. To give you some context, thousands of these switches are used in noise sensitive environments such as broadcast trucks and other Pro AV installs. We had to accomodate with these super cost effective 8X8F model. This is the only one, all other M4300s have fans all the time.Now I understand you and I want to thank you for staying courteous although you are uncomfortable with the running temperature (which stays within specs).I can propose you to run another version of the M4300 firmware, before the change. This way, your fans will work all the time in the meantime.On our side, we are going to turn this fan behavior into a setting accessible from the Web GUi and the CLI. We are receiving good feedback from our AV customer base, but you are providing strong feedback too, and I'm willing to add this to our customer enhancements list.This won't happen in the week, we first need to assess feasibility and plan for it. I can't commit for an ETA at this stage, but we're going to do our best to make it happen in a reasonable time-frame, I hope within a quarter.Until then, I hope you can download another firmware. Thank you. Regards,

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	54^oC	54^oC
System	67^oC	66^oC
Max Operating Temperature	88^oC	88^oC

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	45^oC	43^oC
System	54^oC	52^oC
Max Operating Temperature	83^oC	83^oC

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 for your message. Yes, with latest software the M4300-8X8F has fans off until ambient temperature is above a threshold. This doesn't impact MTBF and many customer requested it. Now you are right, we are working on a new setting in the configuration for selecting quiet mode or fan mode on demand. The ETA isn't firm at this stage but I'll come back to the Community to pre-announce it with a schedule. I would say three months by now, if it can help.

M4300-8x8F. I upgraded to 12.0.9.3. Still have Amber Fans LED and Fans "Stopped" in Web Interface.
Has there been any progress on this issue? When will we have an option to leave the Fans "ON"?

  So we can stay tuned.

    Upgraded today to 12.0.11.11. And the last post on this thread was over 4 months ago. The fans still do not start. The Temperature status on the System main page for me is: MAC, 56 degrees C, System, 58 degrees C. This is WAY too hot for electronics. And yet the fans do not turn on.
    
    Looking for a resolution, PLEASE!
