Follow the guide below to determine the necessary setup steps for your environment.

Step 1: Establish Physical Connectivity to the Internet

In many cases, a wired Ethernet connection will be provided by your ISP. This type of connection includes DSL, Cable
and Managed Internet Connections. It is also possible to connect to the Internet via high speed cellular access, in which
case you should proceed to the appropriate section in this guide.
Once an Internet Connection has been established, the U115 will try to retrieve its configuration from the network, and if
successful, may perform an automatic reboot to pick up the new configuration. This should occur within the first 2-3
minutes after initial power on. Wait for a steady GREEN ONLINE light on the front panel to indicate the U115 is ready for
use.
