Apple Power Macintosh 4400 - Manual (Page 52)

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 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.
Use the thumbscrews and metal clips on the connectors to create a tight,
reliable connection.
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.
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.
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.
