Step4
Upgrade an application file.
Using FTP, you can upload an application file from the client to the server (the U200 series device), and
overwrite the original main application file to implement the application upgrade. The upgraded
application file takes effect when the device reboots.
# Upload file
main_.bin
from the PC to the device, and saves it as
main.bin
.
ftp> binary
200 Type set to I.
ftp> lcd d:\update
Local directory now D:\update.
ftp> put main_.bin main.bin
200 Port command okay.
150 Opening BINARY mode data connection for main.bin.
226 Transfer complete.
z
When you upgrade an application file, if a file having the same name with the uploaded file exists
on the server, the system overwrites the file on the server directly.

For details about the
put
command, refer to the accompanying documentation.

You can upgrade a configuration file using the same method as upgrading an application file. A
configuration file can be modified by a text editor. You can modify a configuration file and then
download the modified configuration file to the device, and the modification takes effect after the
device reboots.
Step5
Back up an application file.
Using FTP, you can back up an application file by downloading it from the server to the client.
# Download file
main.bin
from the device to the PC, and save it as
main_.bin
.
ftp> get main.bin main_.bin
200 Port command okay.
