To access the Web-browser interface you must first enter a user name and 
password. The administrator has Read/Write access to all configuration 
parameters and statistics. The default user name and password for the 
administrator is “admin.” 

Home Page

When your Web browser connects with the switch’s Web agent, the home 
page is displayed as shown below. The interface displays the Main Menu on 
the left side of the screen and the selected menu on the right side. The 
Main Menu links are used to navigate to other menus, and display 
configuration parameters and statistics.
