boot location.

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.

the Dell Networking OS image that you want to use.
4. (Optional) Set the secondary and default boot locations by entering the following commands:
BOOT_USER mode
BOOT_USER# boot change secondary

Restoring Factory-Default Settings
When you restore factory-default settings on a switch, the existing NVRAM settings, startup configuration,
and all configured settings are deleted.
To restore the factory-default settings, enter the restore factory-defaults {clear-all |
nvram} command in EXEC Privilege mode.
CAUTION: There is no undo for this command.
Important Points to Remember
• When you restore the factory-default settings on all units in a stack, the units are placed in standalone
mode.
