MSI-PK, If the #2 power supply is removed all together, do you still get the error even when it is removed?  Also I would take the server to the Minimum hardware configuration, which is removing everything installed but the following; Power it up with that configuration, you can also swap out Power Supply 1 with 2 to test both power supplies under this configuration, and see if the error is still present. If so, then likely the motherboards voltage regulator was damaged in the power outage you had stated. If the error does clear, try adding the removed parts back to the server individually until the return of the error shows which device is causing the issue.  Let me know what you see.
Hi All,  I currently have two Dell Power Edge R720 servers. Both servers have redundant 1100W AC power supplies. Two weeks ago a power outage caused one power supply of each server to malfunction which were replaced under warranty by new power supplies.  Since then the PS2 socket of both servers have been reporting an error, VLT0204 System board PS2 PG Fail voltage is outside of range. Contact support. In order to solve the problem I powered off the system and disconnected the power cords and pressed the power button. I then swapped the power supplies re-connected the power cords and powered on the system. I repeated this step for the second server. Both the systems now did not report the VLT0204 error.  However, the 'VLT0204 System board PS2 PG Fail voltage is outside of range. Contact support.' error message appeared on the front panel again. Repeating the steps above did not resolve the issue. I realised that this time the VLT0204 error became persistent.  Just to be sure that the error is persistent I cleared the hardware logs after which I can still see a critical error in the iDRAC Server Health -> Voltages section. I used the DSET to generate the server report logs which too shows the VLT0204 error message. I can provide the entire zip file if needed.  Should I ignore this error message or should I send it to Dell for inspection under warranty.   Many Thanks  Sohaib
