¿has leído el manual de Lacie donde explica los cambios de la última versión?

Web interface: a new portal to your LaCinema Classic HD
2
Your LaCinema now includes a dedicated Web page. To access the page from
your Web browser, type the local IP address of your LaCinema (the address can
be found at Settings > Network > Network setup).
This Web page allows you to access your product settings.
Note: You can also access the LaCinema Web page by typing
http://Lacinema_hd. Depending upon your network, access using the name may
not be available. In such a case, enter the IP address.

Yo no lo he instalado todavía, pero igual es el acceso web...
