Apple Power Macintosh 9500 Series - Manual (Page 53)

Connecting a SCSI device
Use these general instructions in conjunction with the instructions that came
with your SCSI device:
1 Turn off your Macintosh.
2 Make sure the SCSI device is switched off.
3 Use a SCSI cable to connect the device either to the computer’s SCSI port or to the last
SCSI device already in the chain.
4 Turn on the devices in your SCSI chain.
IMPORTANT Always turn on any external SCSI devices connected to your
Macintosh before turning on the computer itself. Otherwise, your computer
won’t be able to recognize that the SCSI devices are connected to it and your
computer may not be able to start.
Note: If you experience problems after connecting a SCSI device, see the
troubleshooting information in Chapter 6 for possible solutions.
WARNING Do not connect or disconnect any device while the device or
your Macintosh is turned on. Doing so could damage the device, your
computer, or both.
