It drops all connections and then comes back online, Any ideas?

My crystal ball is no better than yours. :)

I would check the obvious such as insufficient power, is it plugged into a UPS and if so what model is it?

Could be ground current if tower grounds are not bonded properly to electrical service grounds?

Beyond that you could swap out with a spare and see if problem stays then you know it is environmentally and if not then RMA it.

I would also upgrade the firmware, not that I think that is the issue but it is out of date.
