So if you have ever inadvertently locked yourself out of your Extreme switch I am going to give you a quick guide on getting back in. Actually this is really not a quick process at all.

***DISCLAIMER***
THIS PROCEDURE WILL ERASE THE ALL CONFIGURATION DATA ON YOUR SWITCH.

This is not a big problem if you make regular backups, also this procedure does not completley wipe the entire switch, so any configs stored in the flash memory are still there.

 You will need the following items to complete this procedure:

• Serial Cable
• TFTP Server - SolarWinds TFTP Server  is FREE
• Config files
• Ethernet cable

1. Connect your laptop or computer via Serial cable to the Console port of the switch. 
2. Reboot the switch
3. Watch the console and enter the bootrom by holding the spacebar down.
4. At the prompt type: “config none” and hit enter.
5. Type “reboot” followed by enter.
6. Let the switch boot normally. Once the switch is booted you can login using the default login information.

At this point you are now able to login to the switch but there is no configuration on it so there are two options for proceeding from here. A. copy a backed up config already on the switch and use it. B. upload a backed up config from a file on your laptop and use it.
