5. Snugly secure the Encore/ST card to the logic board with the
three screws you removed previously; do not overtighten the screws
(Figure 31).
Reattach Heat Sink
1. Position the heat sink clips properly on the heat sink
(Figure 32). Examine the clips and note the short and long
sections, and the dimple. Place each clip so its short section
is closest to you (on the notched side of the heat sink). Please
note, this may be opposite of how the clips were originally
installed.
2. Grasping the heat sink with the notch facing you, guide the
heat sink’s posts into the holes on the Encore/ST card; make
sure the clips do not get caught between the card and the heat
sink (Figure 33). Verify that the heat sink is resting fl at and level
across the top of the Encore/ST card.
3. Lift up a clip and hook it over the back edge of the Encore/ST
card, then pull it toward you. Repeat this process with the other
clip. Grasp a clip with needle-nose pliers, then pull it toward you
and over the front edges of the heat sink and the Encore/ST card
(Figure 34); be careful not to touch the Encore/ST card with
the pliers, and be sure that the clip is grasping the card at
both ends. Repeat this process with the other clip.
4. Visually inspect all four points where the clips attach to the
Encore/ST card. It is easy for the clips to be attached only to the
heat sink, which can lead to destructive overheating of your
upgrade card. Verify that each clip is grasping the card at each
end.
WARNING: The heat sink must be secured firmly, flatly and
completely for reliable and stable operation. If the clips are not
properly attached to the Encore/ST card at all four contact points,
proper cooling of the processor will not occur and the processor will
overheat, causing severe damage to the Encore/ST card. Repairs due
to this damage are not covered by warranty.
Support Note: The following steps address the installation of
your system’s heat sink. Please note, only the single processor
heat sink is pictured, but the procedure is identical for the dual pro-
cessor heat sink. Please also note, that your heat sink may differ from
what is pictured.
