Page 5: Smartpanel Introduction
L2 switch software image is stored in image1, and the SmartPanel software is stored in image2. You can select which software image (image1 or image2) you want to run in switch memory. By default, the switch software is loaded from image1. To run the SmartPanel software, you need to change a software image to image2 and reboot the switch. -

Press the Enter key a few times on the terminal to establish the connection. You will be required to enter a password for access to the switch. (For more information, see the “Accessing the switch” section later in this chapter.) -
Page 7: Setting An Ip Address
As a secure alternative to using Telnet to manage switch configuration, SSH ensures that all data sent over the network is encrypted and secure. In order to use SSH, you must first configure it on the switch. See the “Secure Shell Server configuration”... - Page 8 Description and tasks performed user The user has no direct responsibility for switch management. He or she can view all switch status information and statistics, but cannot make any configuration changes to the switch. The user account is enabled by default, and the default password is user.
