Apple Macintosh Performa 6400 Series - Manual (Page 56)

Connecting a SCSI device
Be sure to read the previous section, “Before You Connect a Device,” before
following the instructions in this one.
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.
IMPORTANT Make sure that the last (or only) device in the SCSI chain has a
terminator and that no other external SCSI device has a terminator.
Otherwise, the computer may not be able to start up.
4 Turn on all 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 up.
5 Install any necessary device drivers (software that makes a device work with your
computer).
Drivers, software needed for a SCSI device, usually come on a floppy disk
with the device. (If no drivers come with the device, contact the device
manufacturer.)
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.
