Question about Powerware 9120 UPS System
The fan in my production powerware 9120 has died, resulting in an over temp alarm. While in this alarm state it apparently is not functioning as a UPS, as I discovered when we lost power last week. The problem is I can't shut this UPS down - it'll bring our whole corporate network down. I've found the directions to replace the fan, I'm wondering if it's possible and safe to do while the system is live.
Hey dude your problem is so simple..below are my solutions.
if you already secured the fans for the replacement then its easy for you to do it, try to totally shut down your UPS removing the input and battery supply. avoid replacing the fans with power, its to dangerous. it consist of almost 400VDC inside in it.
