IMPORTANT:
The total length of the cables in the SCSI chain should not
exceed 6 meters (20 feet). SCSI cables must have a 110-ohm impedance. For
best results.
■
Make sure that the last (or only) device in the SCSI chain has a ter-
minator. Make sure that no other external SCSI device has a termi-
nator.
To ensure accurate transmission of information, a terminator must
be at each end of a SCSI chain. Your computer’s main logic board,
which is the first device in the chain, has a built-in terminator.
The internal CD-ROM drive, which is the last device on the chain,
is also terminated.
Some external SCSI devices have built-in terminators. (Check the
information that came with the device.)
If your SCSI device has a built-in terminator , have the extra built-
in terminator removed. You can attach or remove external termina-
tors yourself.
If you must terminate another device on the chain, de-activate the
termination on the CD-ROM drive.
If the device at the end of the SCSI chain does not have a built-in
terminator, you need to attach an external terminator.
Connecting a SCSI Device
Be sure to read the previous section, “Before You Connect a Device,”
before following the instructions in this section.
Use these general instructions in conjunction with the instructions
that came with your SCSI device.
1.
Turn off your computer.
2.
Make sure the SC
SI device is switched off.
WARNING:
Do not connect or disconnect any device while the device or your
computer is turned on. Doing so could damage the device, your computer, or
both.
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.
