Ignoring the Startup Configuration and Booting from the
Factory-Default Configuration
If you do not want to do not want to boot up with your current startup configuration and do not want to
delete it, you can interrupt the boot process and boot up with the C9000 series factory-default
configuration.
To boot up with the factory-default configuration:
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 startup configuration and reload the
system:
BOOT_USER# ignore startup-config
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.
Recovering from a Failed Start

or from a mis-specified location.
In this case, you can restart the system and interrupt the boot process to point the system to another
boot location.
1. Power-cycle the chassis (pull the power cord and reinsert it).
2. During bootup, press the ESC key when this message appears: Press Esc to stop autoboot...
You enter Boot-Line Interface (BLI) mode at the BOOT_USER# prompt.
3. At the BLI prompt, set the system parameter to ignore the enable password and reload the system:
BOOT_USER mode
BOOT_USER# boot change primary
You are prompted to enter a valid boot device (for example, ftp o r tftp) and a path or filename for
the Dell Networking OS image that you want to use.
