• 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.

Configuration file before resetting the device. This prevents the current device configuration from being
lost. To reset the device:
1. Click System > General > Reset. The Reset page opens.
Reset Page
2. Click the Reset button. Each unit can be reset individually. Resetting the stack master results in
resetting the entire stack. If the master unit is reset, the device is reset, and a prompt for a user name
and password is displayed.
3. Enter a user name and password to reconnect to the Web Interface, if the stack is not part of a full
Linksys One system. If the stack is part of a Linksys One system, login is automatically done from
the Service Router.
Logging Off The Device
1. Click . The system logs off. The Embedded Web System Home Page closes.
