Uploading the Default Configuration File
If you forget your password or cannot access the E3-12C/E5-120/E5-121, you must 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 of 9600 bps with 8 data bit, no parity, one stop bit and flow control set to none. The password will also be reset to “1234” with the IP address of 192.168.1.1.
Important: Uploading the factory default configuration file erases the entire E3-12C/E5-120/E5-121 configuration.
Obtain the default configuration file, unzip it and save it in a folder. Use a console cable to connect a computer with terminal emulation software to the E3-12C/E5-120/E5-121 console port. Turn the E3-12C/E5-120/E5-121 off and then on to begin a session. When you turn on the E3-12C/E5-120/E5-121 again you will see the initial screen. When you see the message "Press any key to enter Debug Mode within 3 seconds", press any key to enter debug mode.
To upload the configuration file
The E3-12C/E5-120/E5-121 is now re-initialized with a default configuration file including the default password of “1234”.
