M1000e Fans at full speed

Hello All,

I have a M1000e and my all of the fans run at full speed all of the time. Currently I only have 5 m600's running. I cannot find any indication of error and all of my firmware is up to date. If I reboot the whole chassis the fans will run at normal speed for a few minutes. Also if I remove one of the PowerConnect M6220 Switches from the enclose, the fan speed will return to normal. Any ideas on how to fix this issue?

RE: M1000e Fans at full speed

Is that switch working properly when inserted back in the chassis? Have you tried swapping M6220 locations? I would also make sure M6220 firmware is up to date, there have been times when incorrect fw has caused these kinds of problems.
