WARNING
While making any establishment and upgrading firmware, please remove physical loop connection
first.
Do NOT power off equipment while firmware is upgrading.
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:
IP Address: 192.168. 0.100
Subnet Mask: 255.255.255.0
Default Gateway: 192.168. 0.254
User Name: admin
Password: admin
System Login
1. Launch the Internet Explorer.
2. Type http:// and the IP address (default IP is 192.168.0.100) of the switch. Press
“Enter”.

function is enabling, you do not need to assign the IP address. The
network DHCP server will assign the IP address for the switch and it
will be displayed in this column. The default IP is 192.168. 0.100
Subnet Mask
Assign the subnet mask for the IP address. If DHCP client function is
enabling, you do not need to assign the subnet mask.
