This reminds me of a problem we had with a brand new 3745 a very long time ago at my previous employer.
One main selling point of the 3745, touted by IBM, was dual power supplies. We had just completed our move to a new data centre. Within 24 hours we lost our network. That 3745 failed. The one flaw in that dual power supply design was a single power cable. And that was the component that failed. We were down for many hours, until a replacement power cable could be flown in from Toronto. (We were in Vancouver) The other failure we had during that move was a "swing DASD" 3380 that just happened to be a sysres pack. Of all the 3380s on the floor, this was the only one painted olive drab. We spent that week making up stories about this 3380 being depth charged in a US submarine or bouncing around in an army drab truck.

I couldn't find any reason on the log or hardware message on why it had power failure. Also our z14 box is connected to two different UPS and they never went down . Where can we find the root cause of this power outage? When i checked our Support element was initialising and not sure what made this power outage. As other machines were all working intact. Any clue or suggestions to look into this?
