d. Touch the static-protective package that contains the microprocessor to any
unpainted metal surface on the server. Then, remove the microprocessor
from the package.
Attention:
v Handle the microprocessor carefully. Dropping the microprocessor during
installation or removal can damage the contacts.
v Do not touch the microprocessor contacts; handle the microprocessor by
the edges only. Contaminants on the microprocessor contacts, such as oil
from your skin, can cause connection failures between the contacts and
the socket.
v Do not use excessive force when you press the microprocessor into the
socket.
v Make sure that the microprocessor is oriented and aligned and positioned
in the socket before you try to close the lever.

e. Align the microprocessor with the socket (note the alignment mark and the
position of the notches); then, carefully place the microprocessor straight
down on the socket. Close the microprocessor bracket frame.
Attention: The microprocessor fits only one way on the socket. You must
place a microprocessor straight down on the socket to avoid damaging the
pins on the socket. The pins on the socket are fragile. Any damage to the
pins might require replacing the system board.
f. Carefully close the microprocessor release lever to secure the
microprocessor in the socket.
Attention: Do not touch the thermal grease on the bottom of the heat sink or
set down the heat sink after you remove the plastic cover. Touching the thermal
grease will contaminate it.
a. Remove the screws (if installed) from the heat sink screw holes on the
system board.
b. Remove the plastic protective cover from the bottom of the heat sink.
c. If the new heat sink did not come with thermal grease, apply thermal grease
on the microprocessor before you install the heat sink (see "Thermal grease"
on page 67).
d. Orient the heat sink so that the side with the number 1 on the label faces
the front of the server.
e. Align the screws on the heat sink with the screw holes on the system board;
then, place the heat sink on the microprocessor with the thermal-grease side
down.
