4.8 Reset the Switch
If you lock yourself (and others) from the Switch or forget the administrator password, you will need to

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 115200 bps 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 or DHCP-
assigned IP.
To upload the configuration file, do the following:
