Action
1. If the over voltage problem is occurring on all
blade servers, look for other events in the log
related to power and resolve those events.
2. View the event log provided by the advanced
management module for your BladeCenter unit
and resolve any power related errors that might
be displayed.
3. If other modules or blades are logging the same
issue then check the power supply for the
BladeCenter unit.
4. If the error continues, replace the system-board
assembly (see "Removing the system-board
