I would think that some of the errors occured at boot up. For instance, the
yellow alarm would have been transmitted to you when the box rebooted
because the CSU was not sending any signal. There is a short transition
period from alarm state to active state also that can account for some
errors. I would benchmark these stats and check them in about 4 to 8 hours
to see if they are coming in constantly, or if this was a one time event.
