I fixed the JetStor 416S raid array IP address by plugging in my laptop to its ethernet port, setting my IP to be on the same subnet, and using the web interface. (After finally tracking down the password, it has been placed in the usual place).
After this change, I powered up the fb40m2 machine and reboot the fb40m machine. This seems to have made all the associated lights green.
Data viewer is working such that is recording from the point I fixed the JetStor raid array and did the fb40m reboot. It also can go back in time before the IP switch over.
