The riser arm may be removed if necessary.
5. Place both hands on either side of the CPU card and lift up. Sometimes a gentle rocking motion
from end to end
(not side to side)
will make it easier to remove the CPU card.
Installing the CPU
1. Hold the CPU card (contacts facing down) with one hand at each end. Notice that there is a notch in
the contact edge of the CPU card.
