5.Install the MACh Speed G3 into your system.

The MACh Speed G3 Upgrade 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.
