Kindly I keep getting this alarm after adding the ups communication card to DCE, I have tried to reinstall DDF for the specific UPS but still not sorted.
Solved! Go to Solution.
Dear @Angwenyi ,
This is not a DDF-file or device problem. There is a standard solution for this error, which is described in detail in Data Center Expert | Alarm "Device status may be inaccurate due to attempt to transfer DDF failed".
I hope this will help you.
