Apple Power Macintosh 9500 Series - Manual (Page 50)

5 Turn on the computer.
Now you hear the computer’s sound through the external speakers.
Note: To control the volume of your external speakers, open the Sound
control panel and choose Volumes in the pop-up menu. Use the Built-in
Headphones slider to adjust the volume for your 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.
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 players, scanners, printers, and tape or cartridge
backup drives. You can attach up to seven SCSI devices to the external SCSI
port of your computer.
Note: In addition to the external SCSI port, your computer has a second,
internal SCSI interface. The internal hard disk drive that came with the
computer and the optional CD-ROM player are connected to this internal
SCSI interface. You can have an Apple-authorized dealer attach an additional
device to the internal SCSI interface. For more information about the SCSI
interfaces, see the Technical Information booklet that came with your
computer.
