Interex MACh Speed G3 User Manual

5. Install the MACh Speed G3 into your system.

• The MACh Speed G3 Upg rade will face the same direc-

tion as the older card that you just removed. In most cases
this is with the heat sink towards the Power Supply. The
connector is designed to fit only one way.

•Holding the card by the edges (do not depress the heat

sink), insert into the connector without twisting. You may
feel two distinct “clicks” as the card seats itself firmly into
the connector.

6. Boot your Mac to test the Card/installation.

• At this point, it is a good idea to check that you get a suc-

cessful boot up “chime”, ensuring that the card is well
seated and working.

• Simply plug the power cord into the Mac, and start up

the Mac. Once you have verified the “chime, you can dis-
connect power, and complete the card installation. If you
do not hear a “chime”, refer to Chapter 5 - Tech Support.

•Note: On some machines it may be mandatory to reassem-

ble the Mac before booting. It is suggested that you test for
a successful start-up “chime” at the earliest period possible
to streamline any troubleshooting that may later be
required.
