Welcome Screen and IP Address
After starting up the appliance for the first time, you should be presented with a panagenda GreenLight welcome screen. If your network has a public DHCP server available, the system might already have acquired an IP address and will display the URL.
Use the shown IP address (interface URL) in your web browser to connect to the panagenda GreenLight web interface.
If DHCP is not available within your network or the panagenda GreenLight appliance did not acquire any IP address, you have to configure the panagenda GreenLight appliance Network Settings.
