• authorization to log on as the boot user

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).

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.)
