Installing a microprocessor and heat sink

Read the documentation that comes with the microprocessor to determine whether

you must update the firmware.

Important:

Some cluster solutions require specific code levels or coordinated code

updates. If the device is part of a cluster solution, verify that the latest level of code

is supported for the cluster solution before you update the code.

download the most current level of server firmware, complete the following steps:

1. Go to: http://www.lenovo.com/support.

2. Enter your product number (machine type and model number) or select Servers

and Storage from the Select your product list.

3. From Family list, select ThinkServer RD220, and click Continue.

4. Click Downloads and drivers to download firmware updates.

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 96 for instructions for applying thermal

grease; then, continue with step 1 of this procedure.

v If you are installing a heat sink that has contaminated thermal grease, see

“Thermal grease” on page 96 for instructions for replacing the thermal grease;

then, continue with step 1 of this procedure.

To install a new or replacement microprocessor, complete the following steps. The

following illustration shows how to install a microprocessor on the system board.

1. Touch the static-protective package that contains the microprocessor to any

unpainted metal surface on the server. Then, remove the microprocessor from

the package.

2. Rotate the microprocessor release lever on the socket from its closed and

locked position until it stops in the fully open position.
