Getting Started With the Web Interface

5.0GETTING STARTED WITH THE WEB INTERFACE

Once the unit is properly installed, you can view its Web interface using an Internet browser. This section provides step-by-step instructions on how to open the Web interface, log in, view monitoring data and view or change configuration settings for the OpenComms EM.

5.1Open the Web Interface and Log In

You must log in each time you open the Web interface. To allow you to log in the first time, the unit is set up with a default User Name, liebert, with no password.

To open the Web interface and log in:

•Open an Internet browser, such as Microsoft Internet Explorer. (One way to do this in Windows is to click on the Start button, then on Programs and finally on the browser program, for example, Internet Explorer.)

•Enter the unit’s IP address or hostname into the browser’s address bar—for example, 126.4.203.246—and press the Enter key. The Login window appears on the right side of the win- dow, as shown below.
