Wiping the config setting to get the Quanta Switches back to default is rather easy if you have experience with Putty, if not, it is still a fairly simple task.
To start off get a computer with a serial port, weather it be a USB-Serial or a built in.
-Open a terminal emulator of your choice. I used Putty.
-Plug the console cable into the console port on the Quanta Switch and to your serial port.
-In your term software select to connect to the serial port on which ever COM it is using. (Putty examples)
-Once you click open you will see what looks like a blank command prompt.(see Putty examples)
-During the boot up you have a chance to intrupt normal boot-up. The first one gives you access to the boot loader, there isn't much you can do in here except make a back-up of config files and change the default boot image.
-The second time loads the switch OS and lets you into the utility menu.
-Press 2 at the prompt in the Putty Examples.
-The menu you get has several options, one is to "Erase Current Configuration"
-This is handy in case you forgot your password, or break something you can't fix.
-After you select that it erases the configuration with a user|pass of admin|blank
-You can then use the reboot option to get into the switch setting as an admin.
ver 1.1 changes - spelling fixes.
