Apple Macintosh 6500 - Manual (Page 61)

Connecting a SCSI device
Be sure to read the previous section, “Before You Connect a Device,” before
following the instructions here. Use these general instructions in conjunction
with the instructions that came with your SCSI device:
1 Turn off your computer.
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.
Use the thumbscrews and metal clips on the connectors to create a tight,
reliable connection.
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
computer 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.
Even if you don’t plan to use a device, you must still turn it on to ensure that
signals pass properly along the SCSI chain.
5 Install any necessary device drivers (software that makes a device work with
your computer).
Drivers 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 Part II for possible solutions.
WARNING Do not connect or disconnect any device while the power to
the device or to your Macintosh is on. Doing so could damage the
device, your computer, or both.
