Recovering from a Lost or Forgotten Password
• 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:
Press Enter to continue........
• If you enter y (yes), the configuration file in Flash memory and the VLAN database file are deleted.
When the default configuration loads, you can reset the password.
Step 1 Elect to continue with password recovery and lose the existing configuration:

Step 2 Load any helper files:
Switch: load_helper
Step 3 Display the contents of Flash memory:
