addition:
– Intel Xeon versions of the 6000 and 7000 Series microprocessors are supported
only on machine types 7145 and 7146.

which microprocessor is installed in microprocessor socket 1 or socket 2.
paired with its original heat sink or a new replacement heat sink. Do not reuse a
heat sink from another microprocessor; the thermal grease distribution might be
different and might affect conductivity.
thermal material that is on the underside of the new heat sink.
If you are installing a new heat-sink assembly that did not come with thermal
grease, see "Thermal grease" on page 170 for instructions for applying thermal
grease; then, continue with step "Installing a microprocessor and heat sink" on
page 165 of this procedure.

of the following procedure.
1. The microprocessor is shipped in a static-protective package and foam.
Remove the static-protective package and foam from the shipping carton and
remove the foam from around the static-protective package.
2. Touch the static-protective package that contains the microprocessor to any
unpainted metal surface on the server. Then, remove the microprocessor from
the package.
3. If there is a plastic protective cover on the bottom of the microprocessor,
carefully remove it.
