Issue 05 (2014-01-16)
By default, fans run in automatic mode. In this mode, the system adjusts the fan speed when detecting that
the board temperature increases or decreases. The automatic mode reduces noises and saves energy without
affecting system running. Therefore, exercise caution when setting the fan speed.
The AR150&200 series does not support this function.
If multiple fans are installed on a fan tray, all the fans run at the speed configured by this command.
