surface. If placed correctly, the Acacia Tree silkscreen will be visible.
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.
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 ( 1 ).
Note: The Processor Board must be squarely aligned in the Processor/Memory
Complex.
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.
Snap shut the four plastic latches that secure the two halves of the
Processor/Memory Complex together.
Tighten the two captive screws that help secure the Processor Baseboard to the
Processor/Memory Complex.
Carefully turn the Processor/Memory Complex over so that you can work on its
underside.
Locate and place the triple beam into position. (Do not install processors or
power pods yet).
Note: Securing the triple beam into position without the processors and power
pods reduces the possibility of stress occurring on the Processor Baseboard
when you install processors and the memory board on the topside.
