Hi all,

I have a T2000 server which does not seem to respond when I power it on. Looking on the console I see the following:

SC Alert: Host Power Failure: MB_DC_POK Fault

SC Alert: Host system poweron failed due to fault at MB/FF_POK.

SC Alert: VOLTAGE_SENSOR at MB/V_VCORE has exceeded low soft shutdown threshold.

I am able to access LOM, and run the following command:

sc> showfaults
ID FRU Fault
0 MB Host Power Failure: MB_DC_POK Fault
1 MB Host system poweron failed due to fault at MB/FF_POK.
2 MB VOLTAGE_SENSOR at MB/V_VCORE has exceeded low soft shutdown threshold.

Is anyone able to advise what the issue could be here, specifically what MB/FF_POK refers to and how, if at all possible, to remedy? I cannot seem to find reference to this anywhere.

Thanks in advance.

looks like a defect mainboard. open a call at sun and get a replacement for your board!

i believe its easier to see through a showenvironment command.

Check the power and make sure it provides the proper voltage or try another power source to isolate that part

sc> showfaults -v
