Do not make other changes to the CLI during the entire upgrade

process. You can ensure that you will not make such changes by opening a

telnet session to the master RE CLI operational mode and issuing the

command. This command locks the configuration procedure.

To prevent traffic loss during the upgrade process, we recommend that

you operate the line cards at 50% line rate. This 50% limit must be

maintained per PFE on each line card.
