service interruption.

information, see the fundamentals configuration guide.
Preparing for the upgrade

 Verify that the switch and the file server can ping each other.
 Run a TFTP or FTP server on the file server.
 Log in to the CLI of the switch.
 Put the new software images on the file server and specify the working directory.
 Back up the Comware software images and configuration file to a PC for future rollback.
