The delay download mode is used by default when the eLMT software package is downloaded during an eSCN230 upgrade. A minimum eLMT package is downloaded first, and then a complete eLMT package is downloaded based on the requirement. If the eSCN230 is upgraded on the eOMC910 and a complete eLMT package (Software.csp) of the same version as the minimum eLMT package is available on the eOMC910, the complete eLMT package can be automatically downloaded to the eSCN230 four hours after the upgrade. If the eSCN230 is upgraded on the eLMT, the eSCN230 is properly connected to the eOMC910, and a complete eLMT package (Software.csp) of the same version as the minimum eLMT package is available on the eOMC910, the complete eLMT package can be automatically downloaded to the eSCN230 four hours after the upgrade. If the eSCN230 is upgraded on the eLMT or a complete eLMT package is required immediately, you can download the complete eLMT package manually. This section describes the procedure for switching a minimum eLMT package to a complete eLMT package.
Prerequisites
· The eLMT directly communicates with the eSCN230, and direct FTP download is enabled between them. Ports 20 and 21 are enabled.
· The minimum eLMT package can be used normally.
Context
· The minimum eLMT package provides only some functions that involve the download of the FTP server software and some MML commands.
· The complete eLMT package provides complete eLMT functions, including MML command running, batch processing, alarm management, tracing management, performance monitoring, equipment maintenance, and self-test.
§ The file name of the complete eLMT package must be Software.csp. If the package is in compressed format, you need to manually decompress the package and download the Software.csp file to the eSCN230 using the FTP server.
§ After the minimum eLMT package is switched to the complete eLMT package, boards do not reset. You can use the functions of the complete eLMT package after you log in to the eLMT again.
§ Except for local operation and maintenance (OM) services, the switch process does not interrupt other services carried by the eSCN230.
Procedure
1. Download the FTP server software. (Optional. Perform this step only when there is no FTP server at the eLMT computer.)
a. In the upper right corner of the eLMT main window, click FTP Tool.
The File Download-Security Warning dialog box is displayed.
b. Click Save to save the FTP server software SFTPServer.exe to the eLMT computer.
2. Double-click SFTPServer.exe.
SFTPServer.exe is decompressed into an SFTPServer folder.
3. Open SFTPServer. Double-click SFTPServer.exe to start the FTP server.
The icon is displayed on the right side of the taskbar after the FTP server is started.
· If the FTP server runs for the first time, go to Step 4.
· Otherwise, go to Step 5.
4. If the FTP server starts for the first time, an FTP password config dialog box is prompted, indicating to modify the password of the FTP server, as shown in Figure 1. In the dialog box, enter the initial password hwbs@com, and enter and confirm the new password. Then, click OK.

. Double-click . The FTP server configuration dialog box is displayed, as shown in Figure 2.
Figure 2 FTP server configuration dialog box
a. Set User name, Password, Working directory. The default user name is admin. Set Working directory to the root directory of the FTP server, which is D:\FTP, and retain default values for other parameters.
The user name, password, and other parameters displayed in the FTP server configuration dialog box can be modified as required.
The method for modifying the password of the FTP server is as follows: Enter a new password in Password and click OK. The FTP password authentication dialog box is displayed. In FTP password authentication, enter the old password and the new password that needs to be authenticated, and then click OK. The password is successfully modified and the new password takes effect.
The method for modifying the FTP user name and other parameters displayed in the FTP server configuration dialog box is as follows: Enter the changed value in the text boxes of parameters and click OK. The FTP password authentication dialog box is displayed. In the FTP password authentication dialog box, enter the valid password and click OK. The parameters are successfully modified.
If you forget the password of the FTP server, delete the FTP server applications, and then download and reinstall them. Then, the user name and password of the FTP server are restored to the default ones.
Working directory must be set to a specified path for storing software and data configuration files because the FTP server cannot access the files not stored in Working directory. Do not set Working directory to a value containing sensitive information or to the father path of the FTP server installation path.
Plain text indicates that data is transmitted in plaintext format. Encrypted indicates that data is transmitted in ciphertext format. Both indicates data can be transmitted in the format of plaintext or ciphertext as required.
To enable encryption transmission, the FTP server can run TLSv1.0, TLSv1.1, or TLSv1.2, and the FTP client must run the same TLS version as the FTP server to properly connect the FTP server.
Click SSL Settings, and configure parameters used for data encryption and transmission using the FTP server on the displayed SSL Settings dialog box. These parameters include Root Certificate FIle Name, Certificate FIle Name, Private Key File Name, and Private Key Password. Ensure that the root certificate file, certificate file, and private key file must be stored in the same directory as SFTPServer.exe.
During an upgrade of the eLMT, if LmtView Common component under Select Software Components is selected, the password of the FTP tool is restored to the default password hwbs@com after an upgrade.
To implement data or file transfer between the FTP server and eSCN230, you must log in to the eSCN230 using the eLMT.
The FTP server is successfully configured.
Run the SPL SOFTWARE command to download the complete eLMT package to the eSCN230 using the FTP server.
You must enter the IP address, user name, and password for logging in to the FTP server correctly and set Delay Download File Supply Flag to YES (Supply File that Support Delay).
Log in to the eLMT again to use the functions of the complete eLMT package.
