Hello It is unlikely that this is a PSU issue since you are experiencing the same problem on two PSUs. This could be a failed piece of hardware attached to the system board, the system board itself, or a cord or component between the PSU and the power outlet. You should remove all unnecessary hardware(Minimum to POST), and bypass equipment like surge protectors and UPSs. If you still experience the same behavior after all of those components have been ruled out then the most likely part will be the system board. Thanks
Hi Folks, I got a wired power supply issue.  My R610 went failure during normal usage. The power supply shows a yellow led light. So I unplug the power cord and put it back in. The power supply showed a green led. But after I press the power button on the front panel, the server didn't start and the led light on power supply went yellow again. After I replaced the power supply, the issue still there with exactly same symptom. The R610 has only one power supply. Any one has some idea about this?
