M5000 won't power up

on an m5000 , I can not power it up, system failure.

XSCF> poweron -a
DomainIDs to power on:00,01
Continue? [y|n] :y
00 :Not powering on :Poweron canceled due to missing component.
01 :Not powering on :Poweron canceled due to missing component.

the only fault that I can see is:

 DDC_A#0 Status:Deconfigured;
*       DDC_A#1 Status:Deconfigured;
*       DDC_A#2 Status:Deconfigured;
*       DDC_A#3 Status:Deconfigured;
*       DDC_B#0 Status:Deconfigured;
*       DDC_B#1 Status:Faulted;
*   IOU#0 Status:Deconfigured;
*       DDC_A#0 Status:Deconfigured;
*       DDCR Status:Deconfigured;
*           DDC_B#0 Status:Deconfigured;
*   IOU#1 Status:Deconfigured;
*       DDC_A#0 Status:Deconfigured;
*       DDCR Status:Deconfigured;
*           DDC_B#0 Status:Deconfigured;

but I can not find a part number?

do I need a new motherboard, or just the one piece that faulted?

Do you have support for the M5000? I would say replacing the faulted part should be enough. You can also try to reset the fault and try again to powerup the system. But go slowly with a poweron -d 0 first and see what happens. If domain 0 is running, you can try to start domain 1.

no support since its older. just a company that swaps parts. I did try the power on each domain and same result , did no reset fault, what command does that? I will try and find it.

Sun shipped some mobo's in COD (Capacity on Demand) mode which means they won't work without a license. Have you got one of those? Do you know the machine history?

Search the web for:
"Capacity on Demand"

From the XSCF use the command version -c xcp and send the output. Depending on the version you might not be able to reset the error...
