Hello everybody. Sorry for my english if there are mistakes and sorry if wrong part of forum.
I have dell md1000 and first power supply seems to fail, so did order new power supplies and installed one. Unit worked fine and fans werent working on full speed like jet. but couple days ago it started again. Checked power supplies and found that on first there no DC led (according to documentation).
If anyone experienced that issue before, what might be a solution? Bad midplane board or ........ I really dont even know what else is bad there =( power supplies for sure are out of scope.
