v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and optional devices, see http://www.lenovo.com/thinkserver.
v To order additional microprocessor optional devices, contact your Lenovo
marketing representative or authorized reseller.
v The microprocessor speeds are automatically set for this server; therefore, you
do not have to set any microprocessor frequency-selection jumpers or switches.
v If you have to replace a microprocessor, call for service.
v The heat-sink FRU is packaged with the thermal grease applied to the underside:
– If the thermal-grease protective cover (for example, a plastic cap or tape liner)
is removed from the heat sink, do not touch the thermal grease on the bottom
of the heat sink or set down the heat sink.
– You must replace the thermal grease if it becomes contaminated or has come
in contact with another object other than its paired microprocessor.
– The thermal grease is available as a separate FRU.
v Do not remove the first microprocessor from the system board to install the
second microprocessor.
v Some models support dual-core processors and quad-core processors. Do not
use dual-core processors and quad-core processors in the same server. Install all
dual-core or all quad-core processors in the server.
