4 Relative Concepts of Data File What is the data file? The data files of the NodeB contain its basic data information. They are independ ent of the NodeB software: Data configuration file : it records NodeB configurat ion information Operation log file : Equipment archives : it records NodeB maint enance information. it records manufacturing information of all boards in the No deB 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 NodeB Download: You can download updated data files from the FTP Server to the NodeB HUAWEI TECHNOLOGIES CO., LTD. All rights reserved Page 41

4 Configuration File Upload and Download GUI Mode Note: The FTP Server has to work normally and connect properly to the NodeB in t he same Intranet. There shall be no firewall between the FTP Server and the Node Transfer Type: How to select Upload and Download Directory 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 HUAWEI TECHNOLOGIES CO., LTD.
