Connecting external Scsi devices | Apple 132 Series guide

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 drives, scanners, some printers, and tape or cartridge backup drives.

You can attach up to seven external SCSI devices to the SCSI port. However, if you have a second internal hard disk connected to this SCSI chain you can attach only six external SCSI devices to the port. All SCSI devices connected to this chain must have their own unique ID number.

Note: In addition to the external SCSI port, your computer has a second, internal SCSI connection. The internal hard disk drive that came with the computer is connected to this internal SCSI interface. If your computer came with a CD-ROM player, it is also attached to the internal SCSI interface. An authorized Apple dealer or service provider can attach additional devices to the internal SCSI interface. For more information about the SCSI interfaces, see the Technical Information booklet that came with your computer.

All devices on the same SCSI chain must have unique ID numbers, but devices on different SCSI chains may use the same SCSI ID number. (For example, you could have a CD-ROM player with ID number 3 connected to the internal SCSI chain and a tape drive with ID number 3 connected to the external SCSI chain.)

IMPORTANT “Before You Connect a Device” and “Connecting a SCSI Device,” both later in this section, 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.
