Working modes of fans on BWS 1600G

Fans on BWS 1600G support two working modes: adjustable speed mode and automatic adjustment mode. In adjustable speed mode, the fan speed can be manually set to high speed, low speed, or stop. In automatic adjustment mode, the temperature of each board on an NE will be periodically detected at an interval of 1 minute. Each board has its own temperature thresholds. The system control board checks the temperature of each board. The system control board increases the fan speed upon detecting that the temperature of one board exceeds the upper threshold and decreases the fan speed after detecting that the temperature of all boards is lower than the lower threshold. Therefore, the system control board can determine the appropriate fan speed and automatically adjust the speed.
