My Promise Pegasus R6 unit used to auto shut down when Windows 7 was shutting down.

Now the unit is connected to a Windows 11 computer but it won't go to shut down when the computer shuts down. I would like to make sure it auto shuts down when the computer shuts down for example in case that there is a power failure and the APC Back 900 Pro UPS attached to the computer dictates the computer to shut down.


can someone please help me find the proper settings or explain how to do so?


thank you very much in advance for your help 🙏
