Option 1
1. Login to the CLI of the Switch to clear the current running configuration

This command resets the configuration to the factory defaults without powering off the switch.  When you issue this command, a prompt appears to confirm that the reset should proceed.  When you enter y, you automatically reset the current configuration on the switch to the default

2. Reboot the switch

4. Select Option 6 Erase Current Configuration
5. Select Option 12 if desired to Erase All Configuration Files
6. Select Option 11 to Reboot the switch

*Please Note: 
If you run the "Erase Current Configuration" command from the boot loader of 210/220 switch it will delete the certificate installed on the switch. Once the cert is deleted,  the switch will never try to connect to ExtremeCloud until the certificate is reinstalled. A reinstall of the certificate can only be done via an RMA.
