We have 6 UPS's, all which have different loads and different estimated 'runtime remaining'. I will try to explain my concern.......
UPS1 which our network switch stack is plugged into has 30 minutes remaining.
UPS2 which one of our servers is plugged into has 50 minutes remaining.
My plan was to configure PowerChute to shutdown the server when "Runtime remaining below threshold = 10 minutes". However, If I were to configure this it would mean that the switches on UPS1 would have lost all power whilst UPS2 still had 20 minutes of runtime remaining.
As the switches have now lost all power/battery, Powerchute would not be able to communicate between the UPS2 and the server and would not be able to issue the shutdown command.
Is this correct?
