Multiple Upgrade Recommendation

If you intend to perform multiple hardware upgrades to your iMac, we recom­mend that you complete the installation of the HARMONi first, then install the
remaining upgrades; complete each upgrade and test it before proceeding to the next.

Update iMac Firmware

If your iMac is running a Mac OS version prior to 9.0, you must update the sys­tem firmware, unless you have already done so in the past.

1. Insert the Mac OS 9.x CD into your computer’s CD-ROM drive. Open the
CD Extras folder and locate the Firmware Update folder containing the
About iMac Firmware Update 1.2 document.

2. Double-click the About iMac Firmware Update 1.2 file. Print and read the
instructions. Close the document.

3. Carefully follow the instructions to update the firmware on your iMac; if the
firmware on your iMac is up to date, no update will occur.

Install Sonnet Software

1. Insert the Sonnet Installer CD into your computer’s CD-ROM drive. Double­click the HARMONi Installer icon to start the utility.

2. Click the Install button to start the software installation; the process takes just
a few seconds.

3. After the software installation is complete, click the Shut Down button to
shut down your computer.

Quick Start Guide for HARMONi G3

Support Note: Before proceeding with any other part of this installa-

tion, you must ensure that your system has the latest firmware installed.
If you have already installed Mac OS 9 or later, you may skip this section and go
to the next section, Install Sonnet Software.

Support Note: Before proceeding with the HARMONi hardware

installation, you must run the Crescendo/WS and HARMONi Install
application. Otherwise, your system will not operate with HARMONi installed.

Also, ensure your system is NOT booted in Mac OS X, nor Mac OS X Classic
mode; the Sonnet installation software will only function in Mac OS 8.1 through
OS 9.x. Quit any open applications and disable any security software installed in
your system. Please note that this installer only needs to be run once, prior to the

hardware installation.

Support Note: Please familiarize yourself with the following instructions

before beginning the installation. If you feel you are unable to install the
computer hardware, please contact a qualified computer technician. Sonnet
strongly recommends that a qualified technician perform this installation.

Before proceeding with the installation, we recommend that you make a backup
of important information on your hard drive prior to installing new hardware or
software.

Shut Down and Open Computer

1. If you have not already done so, shut down your iMac. If the computer has

been on for any length of time, wait a couple of minutes for it to cool before
beginning the installation.

2. Disconnect all cables from your iMac, including the power cable. If necessary,

move your iMac to an area with a flat, level surface where you can freely
work.

3. To protect the special glare-reduction coating on your iMac’s monitor, place a

clean, soft towel on your work surface (Figure 1). Grasping the built-in han­dle, carefully lift and tilt the iMac over so that the screen is resting face down
on the towel (Figure 1).

4. Locate and remove the screw (#1 Phillips) securing the lower back cover

(Figure 2). Using the built-in handle, pull the cover toward you and away

from the computer; set the cover and screw aside.

Remove Logic Board/Drive Assembly

1. Touch the metal surface of the logic board/drive assembly to discharge static

from your body (Figure 3).

2. Pull out the cables from beneath the clamp on the right side of the logic

board/drive assembly, and remove the screw, if present, securing the clamp
on the left side (Figure 4). Using a flat blade screwdriver, unscrew the thumb­screws securing the large connector to the assembly, then disconnect the
cable.

3. Disconnect the remaining connectors from the logic board/drive assembly

(Figure 5). Remove Connector 1 by pressing in its locking tab and pulling

the connector straight out. Remove Connector 2 by pulling it straight out; if
there is a bracket around this connector, remove it along with the connector.
Remove connector 3, if present, by pulling it straight out.

Support Note: To avoid regenerating a static charge in your body, do

not walk around the room until after you finish the installation, reassem­ble and close the computer.

When disconnecting cables from the logic board/drive assembly, do not pull on
the wires; always pull on the connectors.

Support Note: When handling computer products, take care to prevent

components from being damaged by static electricity; avoid working in
carpeted areas. Handle electronic components only by their edges and avoid
touching connector traces and component pins.

4. Move the cables off to the sides of the logic board/drive assembly (Figure 6).

5. Locate the two screws (#2 Phillips) inside the plastic handle (Figure 6), then

remove them; set the screws aside.

6. Using the handle, carefully lift the logic board/drive assembly out of the

computer (Figure 7); when it becomes possible, use both hands to support the
assembly.

7. Set the logic board/drive assembly on a clean, flat surface, with the curved

portion of the assembly facing you (Figure 8).

Remove Processor Card

1. Unhook a long edge of the metal shield covering the processor card, then

remove it from the logic board/drive assembly (Figure 9).

2. While grasping the underside the logic board/drive assembly and the top of

the heat sink clip with one hand, use a flat blade screwdriver to carefully
unhook the heatsink clip from the processor card shield (Figure 10). Remove
the clip and set it aside.
