Replacing the Processor

1Unpack the new processor.

2Ensure that the contacts on the bottom of the replacement processor are free from dirt or other foreign material.

3Align the notched edge of the replacement processor with the tab on the processor frame. See Figure 3-16.

NOTICE: Use caution when removing and installing the processor. Damaging the processor socket connectors can damage the system board.

4Carefully set the processor in the processor frame. Ensure that the notched edge of the processor fits securely over the matching tab on the processor frame. Do not press down on the processor. If the processor is seated correctly, it should fit snugly in the socket frame. See Figure 3-16.

5Lower the retention latch onto the processor, and then rotate the release lever latch back toward the system board until it snaps into place.

6Clean the thermal grease from the bottom of the heat sink.

NOTICE: Ensure that you apply new thermal grease. Applying new thermal grease is critical to ensuring proper thermal bonding as well as optimal processor operation.

7Apply new thermal grease to the top of the processor.

8Place the heat sink assembly back onto the heat sink assembly bracket and tilt the heat sink assembly down on the system board. See Figure 3-15.

9Align the two captive screws properly with the system board, then tighten them to secure the heat sink assembly to the system board.

10Close the system. See "Closing the System" on page 41.

11Reconnect the system to the electrical outlet, and turn on the system and attached peripherals.

Cooling Fans

The system contains two cooling fans, one for the processor and one for the card cage. Each contains a shroud that is part of the cooling fan assembly. The fan and shroud are replaced as a unit.

NOTE: If you are removing the larger processor cooling fan, you must first remove the heat sink and shroud assembly. See "Removing the Processor" on page 62 (however, do not remove the processor) and Figure 3-17.

Removing the Cooling Fans

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer and protecting against electrostatic discharge.

1Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.

2Open the system. See "Opening the System" on page 41.
