Hi,
You may try with another set of Power supplies if you have OR you may try updating the Power Management Controller (ML/DL G6 Servers).

Try any of the above links depending on the OS on your server.

Re: ML350 G6 Server: Error reading power values from microcontroller
In addition to ensuring that there is a valid version for the power management controller and also re-flashing it with the latest available version, you may also perform the following in case the issue persists.
Power the server OFF.
Reset iLO 2 using the iLO 2 web page, under "Diagnostics" click the "Reset" button.
Power the server ON.
If the issue continues, run a test within iLO diagnostics and check for any failed tests.
If this condition is still occurring, perform the following:
Power the server OFF.
Remove AC power from the chassis (remove the power cords) for at least 20 seconds, then restore AC power.
Power the server ON.

Re: ML350 G6 Server: Error reading power values from microcontroller
Hi Suman_1978, thanks for the links, the server runs Microsoft server 2016 Hyper-V host, so I have tried Winx64 version of the flash, but have got a following error message:
"The software is not supported for installation on this system. Unable to communicate with the Power Management Controller. You may able to correct this problem by cycling power"
Tried following:
Shut down server, disconnect power cabled from it. Waited 5 min. Connected power, log into iLO2 interface, reset iLO2. Started server.
No any improvements, result is still the same.
Unfortunately do not have now pair of power supplies to replace, may find in few day.
Any other suggestions?
Regards.

Re: ML350 G6 Server: Error reading power values from microcontroller
Hi Paul,
Thanks for suggestions. Did all that, except iLO2 DiagnosticTest, could not find how to do it.
Situation still the same.
Tried to run Power Management Controller flash update, no success, got following error:
"The software is not supported for installation on this system. Unable to communicate with Power Management Controller. You may be able to correct this situation by cycling power..."
Any other suggestions will be greatly appreciated.
