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

Methods for loading the board software on BWS 1600G and their respective application scenarios
Currently, BWS 1600G supports the following board software loading methods: 1. Using the Navigator (unified NE communication tool of OptiX products): This method is referred to as Navigator-based loading in the following context. The loading page varies slightly depending on Navigator versions. 2. CLI dedicated to BWS 1600G: Files to be loaded are uploaded to the NE, and then downloaded from the NE to boards. The loading is started by issuing a command to the NE. This method is referred to as CLI-based loading in the following context. Application scenarios: Navigator-based loading: 1. Common small files, such as FPGA files and parameter table files. 2. During remote loading, only a few boards of the same type, for example, FIU, M40, or OAU, need to be upgraded on an NE subrack. 3. Generally, Navigator-based loading is recommended. CLI-based loading: 1. Remote loading of large files, which are mainly *.dbd board software files. (*.dbd files are converted from *.esw files using the clamv.exe tool.) 2. For remote loading, a large number of boards of the same type, such as LWF, LWS, LRS, or LRF, need to be upgraded. The CLI-based loading method is designed for this special scenario and is recommended.

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.

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.

Differences between the extended ECC and manual modes of the OptiX BWS 1600G
In the automatic mode of the extended ECC, you do not need to manually specify the server and client. The IP addresses of NEs can be automatically generated on the same network segment. In manual mode, you need to manually specify the server and client.

Whether an OHP2 board of a BWS1600G can be replaced by an OHP board of a BWS320G
An OHP2 board of a BWS 1600G cannot be replaced by an OHP board of a BWS 320G. BWS 320G also has 71OHP and 72OHP boards.
