Recovering from a Lost or Forgotten Password
Procedure with Password Recovery Disabled
If the password-recovery mechanism is disabled, this message appears:
The password-recovery mechanism has been triggered, but
is currently disabled. Access to the boot loader prompt
through the password-recovery mechanism is disallowed at
this point. However, if you agree to let the system be
reset back to the default system configuration, access
to the boot loader prompt can still be allowed.
Would you like to reset the system back to the default configuration (y/n)?
Caution Returning the switch to the default configuration results in the loss of all existing configurations. We
recommend that you contact your system administrator to verify if there are backup switch and VLAN
configuration files.
• If you enter n (no), the normal boot process continues as if the Mode button had not been pressed;
you cannot access the boot loader prompt, and you cannot enter a new password. You see the
message:

When the default configuration loads, you can reset the password.
