Getting Started

This section provides an introduction to the user interface, and includes the following topics:

• Starting the Application

•Understanding the Interface

• Using the Linksys Management Buttons

• Using Screen and Table Options

• Resetting the Device

• Logging Off The Device

Starting the Application

This section contains information for starting the Linksys User Interface.

Note By default, the IP address of the device is assigned dynamically. The IP address can be changed.

It is recommended to configure the IP address statically, if the system is in stack mode, in order to

prevent the user from disconnecting from the network in the event of master switchover.

To open the User Interface:

1. Open a web browser.

2. Enter the device’s IP address in the address bar and press Enter. An Appendix 1, "Enter Network

Password Page" opens:

3. Enter a user name and password. The default user name is “admin.” The device is not configured

with a default password, and can be configured without entering a password. Passwords are both

case sensitive and alpha-numeric.

4. Click Login The Embedded Web System Home Page opens:

Note If you have logged in automatically via the Service Router user interface, the Tree and Device

views appear and allow you to navigate through the various areas of the web interface. However,

the following page will appear within the frame provided by the Service Router user interface.
