Step 17. If you are instructed to return the microprocessor, follow all packaging 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
Use this information to replace a microprocessor and heat sink
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 38.
Important:
• A startup (boot) microprocessor must always be installed in microprocessor connector 1 on the system
board.
• 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.
• If you are installing microprocessor Intel E5-1403, E5-1407 or Intel E5-1410, attach the microprocessor
information label on the front of the server as the following illustration shows.

• 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.
• 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.
• 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.
• If you are installing a new heat-sink assembly that did not come with thermal grease, see "Thermal
grease" on page 76 for instructions for applying thermal grease.
