Recovering from a Failed Start on the S4810 and Z9000

A system that does not start correctly might be attempting to boot from a corrupted FTOS image or from a
mis-specified location. In that case, you can restart the system and interrupt the boot process to point the
system to another boot location. Use the
command, its supporting commands, and other commands that can help recover from a failed start, see the
uBoot chapter in the FTOS Command Line Reference Guide
Step Task

2 Press any key to abort the boot process.
You enter uBoot immediately, as

image to be used when the system
reloads.

Management Ethernet interface.

gateway for the system.
