instructions, and use any packaging materials for shipping that are supplied
to you. Do not return the microprocessor installation tool.

Replacing a microprocessor and heat sink

About this task
Attention: When you handle static-sensitive devices, take precautions to avoid
damage from static electricity. For details about handling these devices, see
"Handling static-sensitive devices" on page 34.
Important:
v A startup (boot) microprocessor must always be installed in microprocessor
connector 1 on the system board.
v To ensure correct server operation, make sure that you use microprocessors that
are compatible and you have installed an additional DIMM for microprocessor 2.
Compatible microprocessors must have the same QuickPath Interconnect (QPI)
link speed, integrated memory controller frequency, core frequency, power
segment, cache size, and type.
v Microprocessors with different stepping levels are supported in this server. If
you install microprocessors with different stepping levels, it does not matter
which microprocessor is installed in microprocessor connector 1 or connector 2.
v If you are installing a microprocessor that has been removed, make sure that it is
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.
v If you are installing a new heat sink, remove the protective backing from the
thermal material that is on the underside of the new heat sink.
v If you are installing a new heat-sink assembly that did not come with thermal
grease, see "Thermal grease" on page 73 for instructions for applying thermal
grease.
v If you are installing a heat sink that has contaminated thermal grease, see
"Thermal grease" on page 73 for instructions for replacing the thermal grease.
