Note: The BMC system event log, which you can view through the
Configuration/Setup Utility program, also contains several information, warning, and
error messages.
In the following example, the system event/error log message indicates that the

The following table describes the possible system-error log messages and
suggested actions to correct the detected problems.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.

See Chapter 4, “Parts listing, System x3655, Type 7985 and 7943,” on page 93 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
System event/error log message Action
+12V critical over voltage fault
1. If the OVER SPEC LED on the light path diagnostics panel is
lit, or any of the four power channel error LEDs (A, B, C, or D)
on the system board are lit, see the entries about
power-channel error LEDs in “Power problems” on page 46.
(See “System-board LEDs” on page 17).
2. If the actions in “Power problems” on page 46do not identify a
defective component, complete the following steps:
a. Remove the power supplies. Replace the power supplies
one at a time, restarting the server each time, to isolate a
failing power supply.
b. If the server fails to start, replace the power backplane.
Restart the server.
c. If the server fails to start, (trained service technician only)
replace the system board.
