Apple 6400 appendix Connecting a Scsi device, Turn on all devices in your Scsi chain

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:

1Turn off your Macintosh.

2Make sure the SCSI device is switched off.

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.

3Use 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.

4Turn 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.

5Install 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.
