Ignoring The Startup Configuration And Booting From The Factory-Default Configuration; Recovering From A Failed Start On The Z9000 System - Dell Z9500 Configuration Manual

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 Z9500 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.
