NS 1250 failure
This was originally posted on APC forums on 3/21/2020
I have an NS1250 unit that all of a sudden shut down with loss of power to all attached units. I pressed the power button and it started again (screen showed full battery). A few hours later it did it again. I removed it from the circuit. This unit has provided uninterrupted service for about 3 years with no problem.
