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.
(during bootup)
press any key
3. Assign the new location to the Dell Networking OS image it uses when the system reloads.
