Removing A Microprocessor And Heat Sink - IBM x iDataPlex dx340 Series Problem Determination And Service Manual

Removing a microprocessor and heat sink

Read the following important guidelines before you remove a microprocessor that is
not faulty (for example, when you are replacing the system-board assembly).
If you are not replacing a defective heat sink or microprocessor, the thermal
material on the heat sink and microprocessor will remain effective if you observe
the following precautions:
v Carefully handle the heat sink and microprocessor when you remove or install
v Do not touch the thermal material or otherwise allow it to become contaminated.
Notes:
v The heat-sink FRU is packaged with the thermal material applied to the
v You must replace the thermal material if it becomes contaminated or has come in
v The heat sink and the thermal material are available as separate FRUs.
To remove a microprocessor and heat sink, complete the following steps.
1. Read the safety information that begins on page vii and "Installation guidelines"
2. If the system-board tray is installed in a chassis, remove it (see "Removing the
