Recovering from a Forgotten Password on the Z9500
If you configure 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# ignore enable-password
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.
5. Configure a new password.
CONFIGURATION mode
enable {secret | password}
6. Save the change in the running configuration to the startup configuration.
EXEC Privilege mode
copy running-config startup-config

command line.
