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," on page 109 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.
Message

Action
1. Make sure that the fans are
operating, that there are no
obstructions to the airflow, that
the air baffles are in place and
correctly installed, and that the
server cover is installed and
completely closed.
2. Make sure that the heat sink for
microprocessor n is installed
correctly.
3. (Trained service technician only)
Replace microprocessor n.
