4 Disable all ports.
5 Misconfigure the text configuration file.
6 Forget the password and/or IP address.
7 Prevent all services from accessing the Switch.
8 Change a service port number but forget it.
Note: 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) to configure
the Switch.
4.6 Resetting the Switch
If you lock yourself (and others) from the Switch or forget the administrator password, you will
need to reload the factory-default configuration file or reset the Switch back to the factory defaults.
4.6.1 Reload the 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 of 9600bps with 8 data bit, no parity, one stop
bit and flow control set to none. The password will also be reset to “1234” and the IP address to
192.168.1.1.
To upload the configuration file, do the following:
1 Connect to the console port using a computer with terminal emulation software. See Section 3.1 on
page 26 for details.
2 Disconnect and reconnect the Switch’s power to begin a session. When you reconnect the Switch’s
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 Switch.
