Recovering from a Failed Start on the Z9000 System
A system that does not start correctly might be attempting to boot from a corrupted Dell Networking OS image 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. Use the
set command, as described in the following steps. For details about the set command, its supporting commands, and other
commands that can help recover from a failed start, the GRUB chapter in the Dell Networking OS Command Line Reference
Guide.

Restoring the Factory Default Settings
Restoring the factory-default settings deletes the existing NVRAM settings, startup configuration, and all configured settings
such as, stacking or fanout.
To restore the factory default settings, use the restore factory-defaults stack-unit {0-5 | all} {clear-
all | nvram} command in EXEC Privilege mode.
CAUTION: There is no undo for this command.
Important Points to Remember
When you restore all the units in a stack, these units are placed in standalone mode.
