Apple Workgroup Server 6150/66 - Manual (Page 51)

IMPORTANT Before connecting a device to your server, be sure that the server
(and any other device already connected to it) is turned off. Read the
instructions in this section and the instructions that came with your hard disk or
other SCSI device before connecting it to your server.
SCSI devices commonly used with the Workgroup Server 6150 include hard
disks, CD-ROM drives, scanners, printers, and tape-backup drives.
Your server comes with two SCSI devices already installed—an internal hard
disk and a CD-ROM drive. You can connect up to five additional SCSI devices
in a chain. Each device must have its own, unique ID number.
Setting up a SCSI device to use with your server involves
m setting the device’s SCSI ID number
m physically connecting the device to your server
m installing any necessary device drivers (and restarting your system)
Setting the SCSI ID number
See the instructions that came with your SCSI device for information on
setting its SCSI ID number.
WARNING Each SCSI device connected to your server must have its own,
unique ID number between 0 and 6. Using two or more devices with the
same ID number can cause your equipment to malfunction. You could
lose data as a result.
