1. Make sure that the fans are
operating, that there are no
obstructions to the airflow (front
and rear of the server), that the air
baffles are in place and correctly
installed, and that the server cover
is installed and completely closed.
2. Check the ambient temperature. You
must be operating within the
specifications (see "Server features
and specifications" on page 6 for
more information).
3. Make sure that the heat sink for
microprocessor n is installed
correctly (see "Replacing a
microprocessor and heat sink" on
page 418 for more information).
4. (Trained technician only) Replace
microprocessor n (see "Removing a
microprocessor and heat sink" on
page 416 and "Replacing a
microprocessor and heat sink" on
page 418).

1. Remove cpu
2. Check cpu socket pins, any damage
or contained or bending, replace the
