6Turn on the computer.

Now you hear the computer’s sound through the external speakers. (You may also need to set options in the control panel for sound settings in order to hear sound through your speakers. Refer to the “Sound” topic of Macintosh Guide, available in the Guide [h] menu for more information.)

Note: To control the volume of your external speakers, use the Sound & Displays control panel to control volume and to set other options for playing sound through the external speakers. If you are playing an audio CD, you may also need to adjust the volume control in the program you’re using to play CDs.

Connecting external SCSI devices

Your computer has a port for connecting devices that use the Small Computer System Interface (SCSI, pronounced “skuh-zee”). The SCSI port permits high-speed communication between the computer and the device. The SCSI icon appears above the port on the computer’s back panel.

SCSI port

You can connect SCSI devices to the SCSI port in a chain. The first device in the chain plugs into the SCSI port; the second device plugs into the first device, and so on. SCSI devices commonly used with the Macintosh include hard disk drives, CD-ROM drives, scanners, some printers, and tape or cartridge backup drives.

You can have a total of seven internal and external SCSI devices connected to the SCSI port. For example, if your computer contains a factory-installed hard disk drive and the optional internal CD-ROM drive, you can add either one internal drive and four external SCSI devices, or five external devices.

IMPORTANT The next sections—“Before You Connect a Device” and “Connecting a SCSI Device”—contain general instructions for attaching SCSI devices to your computer. Be sure also to follow the specific instructions that came with your external hard disk drive or other SCSI device when connecting the device to your Macintosh.
