Chapter 15 Upgrading or reinstalling the software 759

The set of installed Nortel SNAS 4050 devices you are running in a cluster cooperate to give you a single system view. Thus, to perform an upgrade, you only need to connect to the MIP of the cluster. The upgrade will automatically be executed on all the Nortel SNAS 4050 devices in operation at the time of the upgrade. All configuration data is retained.

You can access the MIP by a Telnet or an SSH connection.

Note: Telnet and SSH connections to the Nortel SNAS 4050 are disabled by default, after the initial setup has been performed. For more information about enabling Telnet and SSH connections, see “Configuring administrative settings using the CLI” on page 483.
