Console

Most devices come with an RS-232 console port, so you can connect to your filer using any dumb terminal, such as Windows HyperTerminal.

If you administer multiple systems, you should consider a network terminal server—a device that provides access to multiple console ports over the network. A console is mostly limited to single connection, but using a terminal server, you can configure the console to be shared among multiple administrators. A network terminal server also provides remote connection to the consoles, so that you can dial in to it and operate your systems remotely.

Command-line interface (CLI)

Among Unix system administrators, the command line is still the most used and favored method of management. And while all NAS vendors provide some form of GUI, the GUI isn't always capable of the same functionality as the CLI. The CLI can be used in both console, telnet,rsh, and ssh sessions.
