A permanent fix is being produced for CR xos0075492 and is available in EXOS 30.3.
As a workaround, you can configure the fan speed from the EXOS CLI using:
debug hal configure forceFanPercent <speed percent>
To set the fans back to their default configurations issue:
debug hal configure forceFanPercent 101
The configured fan speed will remain until a reboot, or until it is disabled (101) as this debug command disables the switches ability to control the fan speed.
Please be aware that setting the fan speed to a ‘reasonable’ value is advised to prevent overheating.
Setting the fans to a similar speed as observed when there is no PoE load is recommended when you have a low PoE load, but should be increased with higher loads.
