Software Installation

Install Mac OS 9 or 9.1 (if necessary)

If you are upgrading to Mac OS 9.x as part of this installation, do so now. Please

note, however, it is not necessary to upgrade to Mac OS 9 to take advantage of the

Crescendo's features and speed. If you are not upgrading your Mac OS software at

this time, skip to the next section, "Install Sonnet Software."

1. Start up your computer from the Mac OS 9.x CD and double-click the Mac

OS Install icon. In the Select Destination window, click the Options button

and click the Perform Clean Installation check box that appears in the subse-

quent screen. Click the Select button. Proceed through the next several

screens until you reach the Install Software window. Click OK, Start, then

Continue, and complete the installation. After the software is installed, quit

the Mac OS Install application and restart your computer from the hard

drive where Mac OS 9.x is installed

Install Sonnet Software

You must install the Sonnet software before you install the Crescendo/7200.

Otherwise, your computer will not operate with the Crescendo/7200 installed.

Support Note:

The following two steps involve downloading software from

Apple's website and installing it in your system, but only if you are using a version of

Mac operating system software prior to Mac OS 8.6. The application, Apple System Profiler

2.1.2, enables you to determine the size and slot locations of your DIMMs (memory).

You do not have to download and install this software, but you may not be able to determine

whether your system meets the memory requirements until after you have opened the

computer.

1. If you are now using Mac OS 8.6 or later, proceed to step 3.

Otherwise, log onto the internet and type in the following:

www.sonnettech.com/support/crescendo7200. Read the information on the

page, then click on the link to download the ASP 2.1.2.smi (Apple System

Profiler) file.

2. Install the Apple System Profiler software.

3. Open Apple System Profiler from the Apple menu. Select the System Profile

tab, then click on the arrow next to Memory overview. Click on the arrow next

to Built-in memory and look at the information listed under Location and Size;

write down this information (Figure 1). Confirm that your system will meet

the memory requirements for the version of operating system software you

are using (Figure 2).

4. Insert the Crescendo/7200 Install diskette into the floppy disk drive. Double-

click the Crescendo/7200 Install icon. Review the Read Me screen for any

known configuration issues with the current software release. By default,

with "Easy Install" selected from the pop-up menu, the required software will

be installed into the active System Folder on the boot drive. If this is ok, click

the Install button; otherwise, select "Custom Install" from the pop-up menu

for more options or select another drive to install the software. The installer

will install the appropriate software into the System Folder of your computer.

If the installation was successful, a dialog box will appear. Click Quit to leave

the installer, then shut down your computer.
