Configuring the FTP server

Configuring FTP server operating parameters

The FTP server uses one of the following modes to update a file when you upload the file (use the put command) to the FTP server:

In fast mode, the FTP server starts writing data to the storage medium after a file is transferred to the memory. This prevents the existing file on the FTP server from being corrupted in the event that anomaly, such as a power failure occurs during a file transfer.

In normal mode, the FTP server writes data to the storage medium while receiving data. This means that any anomaly, such as a power failure during file transfer might result in file corruption on the FTP server. This mode, however, consumes less memory space than the fast mode.

Follow these steps to configure the FTP server:
