Recovering from a Forgotten Password
If you congure authentication for the console and you exit out of EXEC mode or your console session times out, you are prompted for a
password to re-enter.
If you forget your password, follow these steps:
1 Log onto the system using the console.
2 Power-cycle the chassis by disconnecting and then reconnecting the power cord.
3 During bootup, press Esc when prompted to abort the boot process.
You enter Boot-Line Interface (BLI) mode at the BOOT_USER# prompt.
4 At the BLI prompt, set the system parameter to ignore the enable password and reload the system:

BOOT_USER# reload
NOTE: You must manually enter each CLI command. The system rejects a command if you copy and paste it in the
command line.
