Hello Cisco Community,
We experience a power-outage in our site and we expect the power will be handled by the UPS for several time. All the devices are running except for 1 voice gateway (Cisco Router 3900), it was turned off and did not transfer its power in UPS, this affected 8 calls from our contact center. Upon checking on the router, only the left power LED is lit, and the right power LED is off. We unplug and plug the power cable then the router boot cycled itself. See below show version result after unplug and plug:

It only says normal reload. However, what might be the factors that made the router to behave like this? Are we missing something?

Hope someone can help and give their thoughts.
