Note
The dialog boxes described in this section apply to the SCALANCE X‑200RNA devices. The dialog
boxes of the SCALANCE X204RNA EEC were chosen to illustrate the examples. Any significant
deviations from the dialog boxes of the SCALANCE X204RNA are pointed out or shown.
Principle of Web Based Management
The devices of the SCALANCE X‑200RNA product line have an integrated HTTP server for Web
Based Management. If a SCALANCE X-200RNA is addressed using a Web browser, it returns
HTML pages to the client computer depending on the user input.
The user enters the configuration data in the HTML pages sent by the SCALANCE X-200RNA. A
SCALANCE X-200RNA evaluates this information and generates reply pages dynamically. The
great advantage of this method is that apart from a Web browser, no special software is required
on the client.
Requirements for Web Based Management
• A SCALANCE X-200RNA must have an IP address before you can use Web Based
Management, see section "Assignment of an IP address (Page 86)".
• To use Web Based Management, there must be an Ethernet connection between the
SCALANCE X-200RNA and the client computer.
• Use of a Microsoft Internet Explorer, version 8 or higher is recommended.
• All the pages of Web Based Management require JavaScript. You should therefore make sure
that Java Script is enabled in your browser settings.
Note
The browser must not be set so that it reloads the page from the server each time the page
is accessed. The updating of the dynamic content of the page is ensured by other
mechanisms. In the Internet Explorer, you can make the appropriate setting in the "Options >
Internet Options > General" menu in the section "Temporary Internet Files" with the "Settings"
button.
Below the text "Check for newer versions of stored pages", the "Automatically" check box
must be selected.
• Web Based Management is HTTP- or HTTPS-based, so you must also enable access to port 80
or 443 if you have a firewall installed.
