Conditions for the MCA board of the BWS 1600G to determine a wavelength loss and report the CHAN_LOS alarm
Question: What is the condition for the MCA board to report the CHAN_LOS alarm when wavelength monitoring configurations are correct? CHAN_LOS Answer: The MCA board determines a wavelength loss when it detects the following wavelength conditions: 1. The optical power is lower than -40 dBm. 2. The optical power is greater than 5 dBm. 3. A wavelength exceeds the standard wavelength by ±0.14 nm. 4. The signal-to-noise ratio is smaller than 7.5 dB. 5. If the difference between the maximum and minimum optical power is greater than 10 dB, the MCA board determines that the wavelength with the minimum optical power is lost.

Fan working mode of BWS 1600G
Question: What are the working modes of fans on BWS 1600G devices? Answer: Fans on BWS 1600G devices can work in two modes. One is the speed adjustment mode. In this mode, the fan speed can be manually set, including high speed, low speed, and stop. The other mode is the automatic adjustment mode. The system control board regularly checks the temperature of each board on the NE every minute to determine whether the temperature of each board exceeds the threshold. If the temperature of one board exceeds the upper threshold, the fan board enables the high speed mode. If the temperature of all boards exceeds the lower threshold, the fan board enables the low speed mode.
