Installing Additional Components Installing Processors and Memory NOTE Experience has taught that, when installing two (or four) processors, it is better to install the processor which is toward the rear of the extender board before installing a processor at the front of the extender board. This means: install processor CPU1 before installing processor CPU0. Similarly, install processor CPU3 before installing processor CPU2. To install a processor, perform the following steps: 1. Locate the installation position and connector socket on the extender board. Ensure that the socket is clean and that holes are not blocked. 2. Ensure that the cam on the processor socket (Figure 2-7, item 7) is in the unlocked, fully counterclockwise position. Use a 2.5 mm hex driver to unlock the cam. 3. Remove the retention cover (Figure 2-7, item 4) from the CPU module. 4. Carefully lower the CPU module into position, using the mounting screw holes (Figure 2-7, item 2) to align the CPU module with the extender board socket. 5. Carefully position the CPU module above the processor socket using the alignment guide pins (Figure 2-7, item 6) to align the processor connector with the extender board socket. 6. Using the alignment tabs on the processor socket, and corresponding notches on the processor connector, lower the connector pins into the socket (see Figure 2-8 for location of tabs and notches). Ensure that the socket and connector are flush against each other before proceeding. 7. Insert the 2.5 mm hex driver through the opening in the CPU module frame (Figure 2-7, item 5), and rotate the cam on the processor socket (Figure 2-7, item 7) 180 degrees clockwise using a 2.5 mm hex driver. 8. Connect the processor power cable (Figure 2-7, item 1). 9. Place the processor retention cover (Figure 2-7, item 4) over the processor. 10. Tighten the captive T-15 screws (Figure 2-7, item 3) to secure the processor retention cover. Chapter 2 25
