Microprocessor - IBM x3250 M3 Problem Determination And Service Manual

Microprocessor

The following notes describe the type of microprocessor that the server supports
and other information that you must consider when you install a microprocessor:
v The server supports one Intel land grid array (LGA) 1156 dual-core or quad-core
v Read the documentation that comes with the microprocessor to determine
v The microprocessor uses an integrated voltage regulator on the system board.
Removing the microprocessor
To remove the microprocessor, complete the following steps.
microprocessor. The type, speed, and L3 cache of the microprocessor depends
on the server model.
whether you have to update the server firmware. To download the most current
level of server firmware, go to http://www.ibm.com/systems/support/.
1. Read the safety information that begins on page vii and "Installation guidelines"
on page 127.
2. Turn off the server and peripheral devices, and disconnect the power cords
and all external cables.
3. Remove the server from the rack; then, remove the cover (see "Removing the
cover" on page 130).
4. Remove the air baffle (see "Removing the DIMM air baffle" on page 132).
5. Remove the heat sink.
CAUTION:
The heat sink may become very hot during normal operation. Allow time
for the heat sink to cool down before you touch it.
a. Loosen the screw on one side of the heat sink to break the seal with the
microprocessor.
b. Press firmly on the captive screws and loosen them with a screwdriver.
c. Use your fingers to gently pull the heat sink from the microprocessor.

6. Lift the heat sink out of the server. After removal, place the heat sink on its
side on a clean, flat surface.
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.
