6.3 Web Based Management (WBM)
6.3.1 General
The ELS includes integrated Web-Based Management; in other words, it can be
operated using an Internet browser (such as Microsoft Internet Explorer or
Netscape). The modules are operated using a Java applet stored on the ELS that
is loaded by the browser. The browser can load the applet only when a Java
Virtual Machine (JVM) is present. As of Version 6.x, Netscape provides a JVM
integrated in the browser that can be used for Web Based Management. For the
Microsoft Internet Explorer, the JVM Plugin must be installed separately. On the
CD supplied, you will find a suitable JVM from Sun Microsystems. The latest JVM
versions can also be downloaded from the Web pages of Sun Microsystems. For
more detailed information, refer to the appendix of this documentation in the
Section "Internet Browser Settings".
To access the ELS, the IP address must be entered in the address field of the
browser. If there is a DNS server in your network that can interpret the address of
the ELS, you can also access the module using the logical name.
All the information provided by the Java Applet is exchanged with the ELS using
SNMP variables. The Management Information Base (MIB) of the ELS is on the
supplied CD.
6.3.2 Requirements
To access an ELS using WBM, the following requirements must be met:
● Internet Browser
You require a PC with an Internet browser. We recommend that you use a
Microsoft Internet Explorer Version 5.5 or higher or a Netscape Browser
Version 6.1 or higher.
Before your Internet browser will work with the ELS, you must make the correct
settings in the browser.
For more information, refer to Section 6.5 of this manual.
● Firewall
If there is a Firewall installed in your network, please make sure that this is
configured so that the Java Applet can access the SNMP Port 161.
