IBM System x3610 Problem Determination And Service Manual page 102

A single problem might cause more than one error message. When this occurs,
correct the cause of the first error message. The other error messages usually will
not occur the next time POST runs.
Exception: If there are multiple error codes or LEDs that indicate a microprocessor
error, the error might be in the microprocessor or in the microprocessor socket. See
"Microprocessor problems" on page 99 for information about diagnosing
microprocessor problems.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 3, "Parts listing, Type 7942 server," on page 37 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.
