WEB Management
5.1 Configuration by Web Browser
This section introduces the configuration by Web browser.
5.1.1 About Web-based Management
An embedded HTML web site resides in flash memory on the CPU board. It contains
advanced management features and allows you to manage the switch from anywhere on the
network through a standard web browser such as Microsoft Internet Explorer.
The Web-Based Management function supports Internet Explorer 5.0 or later. It is based
on Java Applets with an aim to reduce network bandwidth consumption, enhance access
speed and present an easy viewing screen.
Note: By default, IE5.0 or later version does not allow Java Applets to open sockets. You need to explicitly modify
the browser setting in order to enable Java Applets to use network ports.
Preparing for Web Management
The default value is as below:
IPAddress: 192.168.10.1
Subnet Mask: 255.255.255.0
