Dell M1000e Manually Configure Set Minimal Fan Speed Control

You can manually configure the minimum fan speed of the m1000e so that the chassis maintains a lower operating temperature.

SSH The CMC with the cmc ip address and port 22.  User will be root and calvin unless changed.

Then run:

racadm config -g cfgThermal -o cfgThermalMFSPercent  75

This will set the minimum fan speed to 75%.  You can set it from 0-100%.  Obviously 0% is more like 35% but you won’t be able to tell.

You can view the requested fan speed by the servers in the chassis by running:

racadm getfanreqinfo
