Setting up the built-in web server
You can access the MergePoint Unity switch via an embedded web server that handles most day-to-day
switching tasks. Before using the web server to access the switch, first specify an IP address through the local
port on the back panel of the switch or local UI. See Chapter 3 for detailed instructions on using the user
interface for switching.

if outside access is desired.
