4 Relative Concepts of Data FileWhat is the data file?

The data files of the NodeB contain its basic data information. They are

independent of the NodeB software:

Data configuration file : it records NodeB configuration information

Operation log file : it records NodeB maintenance information.

Equipment archives : it records manufacturing information of all

boards in the NodeB

What is the upload and download?

Upload: You can upload data files from the NodeB to the FTP Server for

viewing, modifying and saving. Upload has no impact on the NodeBDownload: You can download updated data files

from the FTP Server to the NodeB

4 Configuration File Upload and Download

Transfer Type: How to select Upload and DownloadDirectory Name : To specify the directory of the configuration file for Upload

and Download

FTP Setting : To set the FTP Server for file upload and download

Note: The FTP

Server has to work

normally and connect

properly to the NodeB

in the same Intranet.

There shall be no

firewall between the

FTP Server and the

Node
