5. Remove the bezel assembly (see “Removing the blade server bezel assembly”
on page 18 for instructions).
6. Locate the microprocessor socket on the system board.
7. Remove the heat-sink filler.
8. Install the microprocessor:
a. If the socket has a protective plastic sheet over the pin holes, remove the
plastic sheet.
b. Touch the static-protective package containing the new microprocessor to
any unpainted metal surface on the BladeCenter chassis or any unpainted
surface on any other grounded rack component; then, remove the
microprocessor from the package.
c. Pull out and lift up on the microprocessor-locking lever to unlock the
microprocessor socket.
d. Center the microprocessor over the microprocessor socket. Align the
triangle on the corner of the microprocessor with the triangle on the corner
of the socket and carefully press the microprocessor into the socket.
Attention:
v Do not use excessive force when pressing the microprocessor into the
socket.
v
Make sure that the microprocessor is oriented and aligned correctly in
the socket before you try to close the lever.
e. Carefully close the lever to secure the microprocessor in the socket.
9. Install a heat sink on the microprocessor:
a. Remove the plastic protective cover from the bottom of the heat sink.
Notes:
1) Do not set the heat sink down after you remove the plastic cover.
Heat sink Thermal grease
2) Do not touch the thermal grease on the bottom of the heat sink.
Touching the thermal grease will contaminate it. If the thermal grease
on the microprocessor or heat sink becomes contaminated, contact
your service technician.
b. Align and place the heat sink on top of the microprocessor in the retention
bracket, grease side down. Press firmly on the heat sink.
c. Using a screwdriver, secure the heat sink to the retention bracket on the
system board using the two captive mounting screws. Press firmly on the
screws and tighten them, alternating between them. Do not overtighten the
screws.
