5. Firmly grasp the heat sink and lift it off the microprocessor. Store the device in
a safe, clean place with the bottom side up. The thermal material on the fan
sink must stay clean if you intend to reuse the device in the future.
6.
Disconnect the fan-sink power cable from the microprocessor fan-sink
connector (CPUFA1) on the system board. See “System board internal cable
connectors” on page 32 for the location of the microprocessor fan-sink
connector.
7. Lift up the release lever and remove the microprocessor from the connector.
Store the microprocessor in a static-protective bag for possible future use.
8. If you are installing a new microprocessor, continue with step 4 in the
following section.
Installing a microprocessor
Do the following to install a microprocessor:
Attention: When you handle ESD-sensitive devices, take precautions to avoid
damage from static electricity. For details on handling these devices, refer to the
following IBM Web site, http://www.ibm.com/ and use a search term of ESD.
1. Review the safety precautions listed in “Safety information” on page 113.
2. Turn off the computer and attached devices and disconnect all external cables
and power cords; then, remove the cover for Type 6836 (see “Removing the
computer cover” on page 35 or for Type 6846 “Removing the side cover” on
page 48 for details).
3.
Install the microprocessor:
a. Touch the static-protective package containing the new microprocessor to
any unpainted metal surface on the computer; then, remove the
microprocessor from the package.
b. Lift up on the microprocessor release lever to unlock the microprocessor
connector.
c. Orient the microprocessor over the microprocessor connector as shown in
the following illustration. Carefully press the microprocessor into the
connector.
