Working modes of fans on BWS 1600G

11

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.

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.

Whether the fan of BWS 1600G is displayed on the NE panel
The fan of BWS 1600G is not displayed on the NE panel

Whether the fan board on a BWS 1600G can be displayed on the NMS panel
The fan board on a BWS 1600G cannot be displayed on the NMS panel. However, the fan board on an OSN 6800 or 8800 can be displayed on the NMS panel. If a fan board is faulty, the FAN_FAIL alarm is reported. You need to replace the fan board.

Software loading modes and their application environments on a BWS 1600G
Question: What are the software loading modes and their application environments on a BWS 1600G? None Analysis: None Answer: Currently, software loading modes on a BWS 1600G are as follows: 1. The software can be loaded by using the Navigator tool, which is an NE communication tool used for all OptiX series products. This mode is called Navigator tool loading for short in the following content. The software loading page varies slightly with different Navigator versions. 2. The software can be loaded by issuing a command line dedicated for the BWS 1600G. The procedure is to upload the file to be loaded to the NE, and then download the file form the NE to the board. The loading is implemented by issuing a command to the NE. This mode is called "NE command line loading" for short in the following content. Objects applicable to software loading: Navigator tool loading: 1. Common files of small size, such as the FPGA file and parameter table 2. In case of remote loading, only a few boards (such as the FIU, M40, and OAU boards) of the same model on an NE need to be upgraded. 3. This mode is recommended. NE command line loading: 1. Remote large files, which are the .dbd files (Note: The .dbd files are converted from the .esw files by using the clamv.exe tool.) 2. A lot of boards of the same model (such as the LWF, LWS, LRS, and LRF boards) on an NE need to be upgraded in remote loading manner. NE command line loading is recommended in this case and is designed for this requirement. Suggestion and conclusion: None
