Hi I have a SUN machine V240 which is reporting power supply failed.

In the prtdiag voltage sensors you can see FF_UV and P_PWR for PS1 is reporting failed.

What does these sensor refer to? other that power supply PS1 what else need to be replace?

I had the same problem last month on a V245. I am guessing that FF_OV and UV are overvoltage and undervoltage sensors, but I really didn't find anything on this. The PS1 will have to be replaced, that's all.
