The array is powered up and ready to run the Connection Utility when the SP Fault LED shows intervals of amber for one
second and blue for three seconds. If the system is on a network with a DNS server and DHCP, the management IP address can
be assigned automatically. When it is assigned, the SP Fault LED is solid blue. Ensure that the power-up is complete and that the
system is ready before you continue.
