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 25.
5. Touch the static-protective package that contains the new microprocessor to
any unpainted metal surface on the server; then, remove the microprocessor
from the package.
Attention: Use the vacuum tool that comes with the microprocessor to
install the microprocessor. Dropping the microprocessor during installation or
removal can damage the contacts. Also, contaminants on the microprocessor
contacts, such as oil from your skin, can cause connection failures between
the contacts and the socket.
6. Position the microprocessor over the microprocessor socket, using the vacuum
tool. Use the triangular alignment cutout on the microprocessor socket and the
triangular alignment mark on the microprocessor to assist you in aligning the
microprocessor to the socket. Then, carefully place the microprocessor into the
socket. Do not force the microprocessor, it only fits one way onto the socket.

7. Place the microprocessor bracket frame down over the microprocessor and the
microprocessor socket to secure the microprocessor position on the socket.
8. Rotate the microprocessor release lever into the closed position.
Attention: Do not touch the thermal grease on the bottom of the heat sink
after you remove the plastic cover. Touching the thermal grease will
contaminate it.
9. Remove the plastic cover from the heat sink. Install the heat sink on top of the
microprocessor with the thermal grease side down. Attach the heat sink to the
system board by alternating fastening the screws on the sides of the heat sink
with a Phillips screwdriver to apply even pressure to the microprocessor and to
avoid damage.
