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 4, "Parts listing, System x3250 M3 Types 4251, 4252, and 4261," on page 119 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.
