Last night every server connected to our R1500 XR UPS (firmware 3.04) shut down ungracefully. There was no external power event and no devices outside of the UPS reported power loss. Also there were no alarms sent and nothing in the logs indicating failure or a problem.
This has never happened before. Please see the attached screen shot of the various data.
The one thing that stood out to me is that it has apparently been operating at about 55C for at least the past month, which I believe is outside the range, correct? In that case wouldn't it notify me or show a warning in the logs? Could this mean a fan failed?
