Replacing A Microprocessor And Heat Sink - Lenovo System x3100 M4 Installation And Service Manual

Replacing a microprocessor and heat sink

Use this information to replace a microprocessor and heat sink
To install the microprocessor and heat sink on 4U server models with non-hot-swap power supplies,
complete the following steps. For the 5U server model with hot-swap power supplies (Model name: 2582-
F4x), please see the next sub-section.
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. Remove the protective cover, tape, or label from the surface of the microprocessor socket, if any is
present.
3. Rotate the release lever on the microprocessor socket to the fully open position.
Attention: Make sure that the release lever on the microprocessor socket is in the fully open position
before you insert the microprocessor in the socket. Failure to do so might result in permanent damage to
the microprocessor, microprocessor socket, and system board.
4. Carefully grasp the microprocessor and place the microprocessor into the microprocessor socket.
Note: To maintain correct orientation between the microprocessor and the microprocessor socket
during installation, observe the following information:
• The microprocessor has two notches that are keyed to two tabs on the sides of the socket.
• A triangle-shaped indicator on one corner of the microprocessor points to a 45-degree angle on the
system board.
• Do not use excessive force when you press the microprocessor into the socket.
5. Close the microprocessor bracket frame; then, close the microprocessor retention latch and lock it
securely in place.
6. Install the heat sink:
Attention: Do not touch the thermal material on the bottom of the heat sink. Touching the thermal
material will contaminate it. If the thermal material on the microprocessor or heat sink becomes
contaminated, contact your service technician.
a. Align the screw holes on the heat sink with the holes on the system board.
