My OC220 controller alerted me today to a firmware update waiting for the ER707-M2 v1.20.  I proceeded to apply it.  It completed -- or at least the OC220 shows the router's current firmware is Version1.4.2 Build 20260509 Rel.32107, which seems to match the latest firmware reported here:
https://support.omadanetworks.com/us/download/firmware/er707-m2/

It rebooted the router at some point after the scheduled update time, which currently is up and running as my devices are all connected as far as I can tell. Access points and various clients all appear to be working.

But when I view the router in the OC220 now, and click on the Logs tab of the device, it shows this entry which is for the date/time that it applied the firmware update:
 

I can't see anything in the OC220 that seems to be a problem other than this message in the router's logs.
When I view each of my access points (various EAP models), they all show connected and nothing in their respective configuration result logs.

What does this message indicate, and where should I look to correct it?  What should I be checking on my network?

Thanks!
