Note: A reinstall wipes out all configuration data, including network settings. Before reinstalling the software on a Nortel SNAS 4050 device with a working configuration, save all configuration data to a file on a TFTP/FTP/SCP/SFTP server. If you use the ptcfg command in the CLI, the saved configuration data will include installed keys and certificates. You can later restore the configuration, including the installed keys and certificates, by using the gtcfg command. (For more information about these CLI commands, see “Backing up or restoring the configuration using the CLI” on page 730. For information about using the SREM to perform these functions, see “Backing up or restoring the configuration using the SREM” on page 742.) If you want to make separate backup copies of your keys and certificates, use the display or export commands. (For more information about these commands, see “Saving or exporting certificates and keys” on page 574. For information about using the SREM to perform these functions, see “Displaying or saving a certificate and key using the SREM” on page 605 or “Exporting a certificate and key from the Nortel SNAS 4050 using the SREM” on page 607.)

If a software CD was shipped with the Nortel SNAS 4050, you can also reinstall the software from the CD (see “Reinstalling the software from a CD” on

page 767).
