TFTP 

OR

 HTTP

Use the System > File (Copy) page to upload/download firmware or 

configuration settings using FTP, TFTP or HTTP. By backing up a file to an 

FTP/TFTP server or management station, that file can later be downloaded 

to the switch to restore operation. Specify the method of file transfer, along 

with the file type and file names as required.

You can also set the switch to use new firmware or configuration settings 

without overwriting the current version. Just download the file using a 

different name from the current version, and then set the new file as the 

startup file.
