Installation—AGP Graphics and Gigabit Ethernet Models
3. Lift up a clip and hook it over the back edge of the Encore/ST
card, then pull it toward you (Figure 16). Repeat this process
with the other clip.
4. 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 17); 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.
5. 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.
Close Computer
1. Raise the side panel back into place (Figure 18).
2. Return the computer to your computing area if necessary, and
reconnect the power cord and peripheral cables to the computer.
Turn On Computer
Turn on your Power Mac; your accelerated machine should boot nor-
mally. Your installation is now complete.
Support Note: Your Power Mac was designed to operate
efficiently with the side panel closed. Do not operate your
computer with the side panel open; proper air flow over the heat
sink will not occcur and the processor may overheat.
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.
