Sonnet Technologies Presto Plus Processor Upgrade with Mac OS 8 - Manual (Page 7)

9. Remove the Presto Plus card from the anti-static package, making
sure to handle the card by the edges.
10. Orient the Presto Plus card directly over the PDS slot so the rear of the
card aligns flush with the rear of the logic board. Gently press down
until the Presto Plus card is firmly seated in the PDS slot (Figures 6, 7).
If you encounter any resistance, lift the card out of the PDS slot, check
for bent pins, and reinstall the card.
11. Slide the logic board into the computer (Figure 8) by first aligning it
with the inner guides of the computer’s case and then pushing it back
until it fully in place.
12. Replace the back panel and two security screws.
13. Return your Macintosh to your computing area and reconnect the
power and peripheral cables to the computer.
14. Affix the Powered by Sonnet label (Figure 9) to the front of your
computer.
15. Turn on your Macintosh. You should see the Presto extension icon load
during startup.
16. The Presto Plus processor upgrade card has an onboard RAM expansion
SIMM slot with a 32 MB SIMM that adds additional RAM to your
system. For example, if your computer has 10 MB of RAM the Presto
Plus adds an additional 32 MB for a total of 42 MB. To determine the
amount of RAM available to your system, select “About this Macintosh”
or “About This Computer” (depending on the installed System software)
from under the Apple Menu.
17. The Presto Plus features 10BaseT Ethernet via a RJ45 Ethernet port. If
you intend to connect your Macintosh to an Ethernet network, you will
require an unshielded twisted-pair (CAT 3-5 UTP) cable. You will also
need to configure the system software (via AppleTalk and TCP/IP control
panels) to recognize proper Ethernet settings.
Two LED indicators on the Presto Plus provide status information for
verification and diagnostic purposes:
• The LED Link indicator (Figure 10) indicates a valid connection to
a network. When a connection is established, the LED is on; if a
connection is not detected, the LED should be off.
• The LED Transmit indicator (Figure 10) indicates the transmission of
data. When on, the LED should blink on as data is being transmitted.
When no data is being sent, the LED should be off.
