M4300-48X Running Temperature high

Hi John

thank you, I have escalated your case, a Technical Support agent will contact you.

Thanks for your assistance, waiting to hear back from Engineering on my fan speed issue...

Another week goes by with no response...

Greetings,

Found these other cases in forum that were fan/firmware related:

We didn't intentionally raise fan speeds and lower operating temperature in recent 6.6.1.x firmware for our XS708T/XS716T 10G Smart Managed Switches, versus 6.6.0.x before. With latest firmware, we don't show such modification either in our labs: fan speed remains the same.

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. 

Maybe I'n using the wrong word, maybe I should be daying 'Software' instead of 'Firmware"?

The unlucky half-finished 12.0.7.12 specs change for the 8X8F should not affect your models.

And there is just one owner with a XS708T/XS716T  6.6.1.x firmware - which does not have any change in the fan speed tables - reporting a louder switch. Completely unrelated. 

Thanks for the info. The point I was eluding to is that I was told the fans aren't regulated by software. But these cases are indicating that software does control fan speed....

sorry, I meant alluding, not eluding . :smileyhappy: I just want to use these expensive and great switches I bought without having to worry about the burning up because the power supply fans aren't running at all and the case fans are barely running. My M4300-52G fan speeds are perfect and temperature is great. I'm just wanting the same performance fron my 2 M4300-48X switches. If I can get this problem resolved, I plan on buying more M4300s.

Mistaken. The modular power supply (or supplies) fans are temperature controlled only, not firmware/software controls. The switch fan(s) are firmware/software controlled up to some degree.

Shumaku,

I really appreciate your feedback, thank you. I'm learning alot from your comments.:smileyhappy:

Another question, why would a 450W PSU in the M4300-48X have a proper fan speed, as compared to my M4300-52G and none of 4 250W PSUs have any fan speed in the M4300-48X? 

Also, why would the M4300-48X case fan speed be slower than the M4300-52G fan speed? They are Stacked and all running the same 12.0.7.15 software?

For the modular power supplies, I can only assume that the fans are temperature and/or load controlled. The few M4300 we're operating are on the hot top of racks, so there is high fan activity - simply becaue of the high temperatures around. 

Has nobody from Netgear established a contact with you?

Yes, they asked for logs and a few questions 2 weeks ago. No answers yet...

I'm looking at buying into Netgear, and a M4300 stack looks compelling, but the various reports of high temperature issues with the M4300-48X give me pause. Has there been any recent progress on this problem?

Various? Can just find this thread - the oddity with the 8X8F LED going amber with the intentionally allowed "fan-free" operations on lower temperatures was explained above.

Mostly this thread and this amazon review:

"They run great, good throughput, working as expected, BUT, they run SUPER HOT. In a properly cooled computer room and equipment rack, if you put your hand on the bottom of the switch, you can almost not keep it there, it's burning hot. We've had 2 fail already, it will be very hard to convince me it's not from overheating."
