Chapter 6: Installing an Additional Processor

Installing the Board in a System with Three or Four Microprocessors

When installing a board that contains three or four microprocessors, complete the following
procedure:
1. Place the bottom half of the Processor/Memory Complex on a clean ESD-protected work
surface. The bottom half of the complex has wider rails as compared to the top half. Be sure
that the rail side of the complex is in contact with the work surface.
2. Carefully place the Processor Baseboard topside up into position on the bottom half of the
Processor/Memory Complex. Be sure that the guide pins align with the holes on the Processor
Baseboard. If placed correctly, the Acacia Tree silkscreen will be visible.
NOTE
3. Place the top half of the Processor/Memory Complex over the Processor Baseboard. Be sure
that the guide pin relations are correct. The Processor Baseboard should be between the two
Processor/Memory Complex halves.
4. Snap shut the four plastic latches that secure the two halves of the Processor/Memory Complex
together.
5. Tighten the two captive screws that help secure the Processor Baseboard to the
Processor/Memory Complex.
6. Carefully turn the Processor/Memory Complex over so that you can work on the underside.
7. Locate and place the triple beam into position. (Do not install microprocessors or power
pods).
NOTE
Secure the triple beam by tightening the four thumbscrews on the ends of the beam. Do not tighten
the captive screws on the top of the triple beam at this time.
9. Carefully turn the Processor/Memory Complex over so that you can work on the topside.
10. Install the processors and power pods into the top half of the Processor/Memory Complex as
described in "Installing an Additional Processor" in Chapter 6.
11. Install the triple beam.
12. Insert the sheet metal baffle located to the front of the processors or CPU thermal dummies in
the Processor/Memory Complex. To insert the baffle, press the flexible retaining tabs in as
you slide the baffle into position.
13. Install the memory board into the top half of the Processor/Memory Complex as described in
"Removing and Installing Memory Boards" in Chapter 5.
14. Carefully turn the Processor/Memory Complex over so that you can work on the underside.
15. Remove the triple beam by first loosening the four thumbscrews found on the ends and then
the captive screws found on the top of the triple beam. Lift the triple beam off the complex.
The Processor Board must be squarely aligned in the Processor/Memory Complex.
Securing the triple beam into position without the microprocessors and power pods
reduces the possibility of stress occurring on the Processor Baseboard when you
install microprocessors and the memory board on the topside.
