Chapter 4 The Web Configurator 8 Change a service port number but forget it. " Be careful not to lock yourself and others out of the switch. If you do lock yourself out, try using out-of-band management (via the management port or console port) to configure the MM-7201. 4.6 Resetting the Switch If you (and others) forget the administrator password or are no longer able to access the MM7201 (using in-band or out-of-band management), you need to reload the factory-default configuration file. Uploading the factory-default configuration file replaces the current configuration file with the factory-default configuration file. This means that you will lose all previous configurations and the speed of the console port will be reset to the default values in Section 2.2.2 on page 38. The password will also be reset to "1234" and the IP address to 192.168.0.1. To upload the configuration file, do the following: 1 Connect to the console port using a computer with terminal emulation software. See Section 2.2.2 on page 38 for details. 2 Disconnect and reconnect the system's power to begin a session. When you reconnect the power, you will see the initial screen. 3 When you see the message "Press any key to enter Debug Mode within 3 seconds ..." press any key to enter debug mode. 4 Type atlc after the "Enter Debug Mode" message. 5 Wait for the "Starting XMODEM upload" message before activating XMODEM upload on your terminal. 6 After a configuration file upload, type atgo to restart the MM-7201.
