changes to the configuration are required.
The unit can either be configured by using the on-board Mode (M) and Set (S) buttons, or
through a PC connected directly to the Ethernet port by surfing to the web console.
Only limited configuration is available through the button method, and more advanced
configuration requires web console access. Most installations will require no configuration
changes, the unit being supplied ready for installation at default.
A minority of sites may require minimal configuration changes at installation, and most of these
will be achievable through the button config.
