         If the call home to IBM was successful, you can expect a service call from IBM. In the meantime, perform these steps:

               If voltage problem are occurring on multiple blade servers,
look for other events in the event log related to power and resolve those events.

                     Note: If voltage problems are occurring on multiple blade servers in the same power domain,
the problem might be in one of the power modules that power that domain (log in to the
advanced management module to see the power modules that are
associated with each power domain). Therefore, replace the power modules,
one at a time, to see if the problem is resolved.

               
               Check the change history for blade server service processor firmware and BIOS for any issues related to this
problem.  If so, update the blade server firmware and BIOS.
