Is this MB, which needs replacement ?

Hello,
I am getting below error in fmadm output. This server is not in support, so can't reach them. Is it showing that motherboard is faulty and should be replaced ? It was rebooted a week back and then, there were no errors

# fmadm faulty

Reset the errors from the ILOM (and/or Solaris) and do a max POST to check the hardware. If the error is still there, strip the server of all not needed stuff (no PCI cards, minimal RAM and so on) and check again.
