If the “nvram show” command in console returns the “*** command status = 0” result, the configuration in the NVRAM is gone.

Please copy & paste the script below to a text file. The script file is to run under Linux minicom terminal emulator. Please edit the script and change the MAC address to the unit’s MAC address.

If no Linux minicom is used, please issue the commands between the quotation marks manually, one by one. Make sure enter the command “nvram commit” at the end, before “reset” (restart) the switch.
