4.Open the processor cage (Figure 3-13).

a.Grasp the processor cage handle and rotate the handle upward.

b.Use the handle to rotate the cage closure 90 degrees toward the front of the assembly until it stops.

IMPORTANT: Ensure the processor slot is entirely exposed. The processor must clear the cage closure for proper installation.

5.Locate the appropriate processor slot (Module 0 or Module 1) to install the processor into (Figure 3-13).

6.Remove the plastic airflow blocker covering the processor slot.

7.Remove the protective dust cover from the processor socket.

8.Ensure that the cam on the processor socket lock is in the unlocked, counterclockwise position. The zero insertion force (ZIF) socket for the processor is locked and unlocked by half of a full turn of the processor install tool. Rotate the cam counterclockwise 180 degrees (half turn) unlocks the socket. A clockwise 180 degree rotation locks the socket.

CAUTION: Attempting to turn the locking mechanism more than 180 degrees can severely damage the socket.

9.Remove any protective packaging from the processor.

NOTE: Protective covers are installed to protect connector pins. Save the covers for future use.

10.Inspect the processor pins and verify that the pins are not bent.

11.Align the alignment holes on the processor with the alignment posts on the processor cage, and carefully lower the processor onto the processor socket (Figure 3-14).

CAUTION: Do not press the processor into the socket. When properly aligned, the processor pins seat into the socket. No additional pressure is required. You can damage pins if too much pressure is applied.

12.Lock the processor into the socket on the processor board (Figure 3-14).

a.Unfasten the processor install tool (2.5-mm driver) from the tool holder on the processor board.

b.Insert the processor tool into the hole that runs down the side of the heatsink.

c.Rotate the processor tool clockwise 180 degrees.

CAUTION: Attempting to turn the locking mechanism more than 180 degrees can severely damage the socket.

d.Refasten the processor install tool to the tool holder on the processor board.

13.Reconnect the processor power cable into the connector cable that attaches directly to the processor board.

14.Close the processor cage (Figure 3-13).

a.Grasp the processor cage handle and rotate the cage closure inward toward the rear of the assembly until it is completely closed.

b.Push the handle down until it is flush with the cage.

15.Replace the processor board assembly. See “Replacing the Processor Board Assembly” (page 74).

16.Replace the memory carrier assembly. See “Replacing the Memory Carrier Assembly” (page 66).
