Recovering from a Failed Start
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
setenv command, as described in the following steps. For details about the setenv command, its supporting commands, and
other commands that can help recover from a failed start, see the u-Boot chapter in the Dell Networking OS Command Line
Reference Guide.
1. Power-cycle the chassis (pull the power cord and reinsert it).
2. Hit any key to abort the boot process. You enter uBoot immediately, the => prompt indicates success.

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 {stack—unit—number |
all} {clear-all | nvram | bootvar} command in EXEC Privilege mode.
CAUTION: There is no undo for this command.
