Connecting a SCSI device
After you read “Before You Connect a SCSI Device” earlier in this chapter, follow the instructions below. Use these general instructions in conjunction with the more specific instructions that came with your SCSI device.
1Shut down 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. Do not attach or remove a terminator while the computer or any device is turned on.
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.
Use the thumbscrews and metal clips on the connectors to maintain a tight, reliable connection. Do not overtighten the thumbscrews.
4Turn on all devices in your SCSI chain.
IMPORTANT Always turn on all 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 needed for a SCSI device usually come on a floppy disk with the device. (If no drivers come with the device, contact the device’s manufacturer.)
Note: If you experience problems after connecting a SCSI device, see the troubleshooting information in Chapter 10, “Solutions to Common Problems.”
