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 9600 bps with 8 data bits, 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 3.1.1 on page 40 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.
