8. If your computer's expansion card cover does not resemble the one shown in
Figure 8, go to the next step. If your expansion card cover has three notched
baffles as shown in Figure 8, you must break off the two rear baffles so they
will not touch the Crescendo/7200 card when the cover is closed. Use a pair
of pliers to break off the tabs.
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 into
all Power Macintosh 7200/8200 models.
9. 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 9).
Support Note:
Do not touch the DIMMs' connectors; always handle DIMMs
only by their 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.
10. If you going to install, remove, or swap memory on the logic board, do so
now. Using the information obtained from Apple System Profiler, determine
which DIMMs you will remove or swap from, or install into the logic board's
DIMM slots (Figure 10), which are labeled J14 - J17. To remove the DIMMS,
push outward and down on the DIMM ejectors. To install DIMMs, align the
notches of a DIMM over the guides of a DIMM slot, then gently, but firmly
press the DIMM straight into the slot until the ejectors snap completely
closed.
Support Note:
Remember, you must leave at least 8MB of memory installed
on the system's logic board, and install a minimum of 8MB of memory on the
Crescendo/7200 if you are using System 7.5.3 to Mac OS 8.6. For Mac OS 9 and OS 9.1,
you must leave at least 8MB of memory installed on the system's logic board, and install a
minimum of 24MB of memory on the Crescendo/7200.
11. Orient the Crescendo card so the DIMM slots are face up and the bracket is
on the right (Figure 11). 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:
You may install the Crescendo in any of the three PCI slots, but
because of the amount of space occupied by the card with DIMMs installed, we
recommend installing it into the slot labeled A1. If you install it into either slot A2 or A3, you
will not be able to utilize all three PCI slots in your system.
12. Locate the PCI slot labeled A1 and remove its port access cover (Figure 12).
