4.
Center the microprocessor

over the microprocessor socket

.
5.
Align the triangle
2
on the corner of the microprocessor with the triangle on the corner of the
socket and carefully press the microprocessor into the socket.
Attention: Do not use excessive force when pressing the microprocessor into the socket.
6. Close the lever.
Note: A voltage regulator module (VRM) and a heat sink are included in the microprocessor
package.
v Do not set the heat sink down after removing it from the package.
v
Do not touch or contaminate the thermal grease on the bottom of the heat sink. Doing so damages
its heat-conducting capability and exposes the microprocessor to overheating.
v
If you must remove the heat sink after installing it, note that the thermal grease might have
formed a strong bond between the heat sink and the microprocessor. Do not force the heat sink
and microprocessor apart; doing so causes damage to the microprocessor pins. Loosen one captive
screw fully before loosening the other captive screw to help break the bond between the
components without damaging them.
7. Install the heat sink
2
on top of the microprocessor

8. Tighten the captive screws. Alternate between the screws until they are all tightened. Do not
overtighten.
9. Replace the top cover. See “Replacing the top cover” on page 81.
10. Place the node in the rack. See “Replacing the SAN Volume Controller in a rack” on page 55.
11. Reconnect the power cords and any cables that were removed.
12.
Turn on the node.
