5. If you are removing an Intel processor, rotate the locking lever to its full open position (1), raise and rotate the microprocessor retainer to its full open position (2), and then carefully lift the processor from the socket (3). CAUTION: Do NOT handle the pins in the processor socket. These pins are very fragile and handling them could cause irreparable damage. Once pins are damaged it may be necessary to replace the system board. CAUTION: The heat sink must be installed within 24 hours of installing the processor to prevent damage to the processor's solder connections. Figure 7-40 Removing an Intel processor To install a new processor: 1. Place the processor in its socket. 2. If installing an Intel processor, close the retainer. 3. Secure the locking lever. If reusing the existing heat sink, go to step 4. If using a new heat sink, go to step 7. 4. If reusing the existing heat sink, clean the bottom of the heat sink with the alcohol pad provided in the spares kit. 5. Apply the thermal grease provided in the spares kit to the top of the processor and install the heat sink atop the processor. 6. Go to step 8. 7. If using a new fan sink, remove the protective covering from the bottom of the fan sink and place it in position atop the processor. 8. Secure the fan sink to the system board and system board tray with the 4 captive screws and attach the fan sink control cable to the system board. CAUTION: Heat sink retaining screws should be tightened in diagonally opposite pairs (as in an X) to evenly seat the heat sink on the processor. This is especially important as the pins on the socket are very fragile and any damage to them may require replacing the system board. Processor 83

Figure 7-40
Removing an Intel processor
To install a new processor:
1.
Place the processor in its socket.
2.
If installing an Intel processor, close the retainer.
3.
Secure the locking lever.
If reusing the existing heat sink, go to step 4.
If using a new heat sink, go to step 7.
4.
If reusing the existing heat sink, clean the bottom of the heat sink with the alcohol pad provided
in the spares kit.
5.
Apply the thermal grease provided in the spares kit to the top of the processor and install the
heat sink atop the processor.
6.
Go to step 8.
7.
If using a new fan sink, remove the protective covering from the bottom of the fan sink and place
it in position atop the processor.
8.
Secure the fan sink to the system board and system board tray with the 4 captive screws and
attach the fan sink control cable to the system board.
CAUTION:
Heat sink retaining screws should be tightened in diagonally opposite pairs (as in
an X) to evenly seat the heat sink on the processor. This is especially important as the pins on
the socket are very fragile and any damage to them may require replacing the system board.
