Apple Power Macintosh 8500/150 Series - Manual (Page 62)

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 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.
5 Install any necessary device drivers (software that makes a device work with your
computer).
Drivers 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.
Expanding memory
The random-access memory (RAM) in your computer can be expanded.
Installing additional RAM adds more memory chips to your computer and
expands its capabilities. The Technical Information booklet that came with
your computer describes how much additional memory can be installed in
your Power Macintosh.
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.
