Sonnet Technologies Crescendo_7200 Processor Upgrade Card - Manual (Page 8)

Hardware Installation—Power Macintosh 8200 (continued)
18. Replace the logic board into the case (Figure 28).
19. Secure the logic board with the screw you removed previously, then recon-
nect the logic board cables to the their appropriate connectors on the logic
board (Figure 29); verify the connectors are plugged in securely.
20. Replace the power button switch and reconnect the power button cable to
its connector on the logic board (Figure 30); verify the connector is
plugged in securely.
21. Remove the Crescendo/7200 from the anti-static package, making sure to
handle the card by its edges, and lay the card on a flat, static-free surface
(Figure 31).
22. Orient the Crescendo card so the DIMM slots are face up and the bracket is
on the right (Figure 32). Add some support, such as a piece of cardboard,
under the upper left corner of the Crescendo card to keep it level. Align the
notches of a DIMM over the guides of the bottom DIMM slot on the
Crescendo card. Gently, but firmly press the DIMM straight into the slot
until the ejectors snap completely closed. Repeat as necessary with any
remaining DIMMs.

Support Note: When you remove the Crescendo/7200 card from its anti-static
package, you may notice that a DIMM ejector appears to be missing; do not be
concerned. The top right DIMM ejector has been removed to enable easier installation of
the card into all Power Macintosh 7200/8200 systems.
Support Note: Do not touch the DIMMs’ connectors; always handle DIMMs
only by the edges. Please note that DIMMs are designed to fit into the slot only
one way; be sure to align the DIMMs’ notches with the small guides inside the slot.
