4.5 Resetting the Switch
If you lock yourself (and others) out of the switch, you can try using out-of-band management.
If you still cannot correct the situation or forgot the password,
you will need to reload the
factory-default configuration file.
4.5.1 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 3.1.4 on page 39 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.
