What would cause a Ciena switch, or any switch to stop responding but still be powered ON?

We use Frontier's ELAN to connect our offices. After this recent hurricane, we had a power outage. Several days after the outage, SolarWinds shows one of our offices is down during the work day. Staff say there was no power outage nor flickering going on. Walking into the server room, all systems are running, then checking Frontier's Ciena switch it is also up. I'm not sure about the activity lights as I wasn't in the room. We pulled the power and rebooted the Ciena switch and SolarWinds was able to see the office again. I'm wondering, what causes a switch to stop responding but look like it is ON? Just curious if it is power related since we had an storm related outage or, the current work being done on the lines outside after the storm?
