Expanding Your System
Guidelines for Connecting Expansion Boxes
Use the following guidelines when connecting expansion boxes:
• You can connect any combination of external expansion boxes, as long
as you do not connect more than six expansion boxes to the model
with two internal compact disc drives, or seven expansion boxes to the
model with one internal compact disc drive.
• You must attach the 50-pin terminator that comes with your
expansion box to an unused bottom SCSI connector on the back of
an expansion box.
• You should plug all expansion boxes into the same grounded power
strip or electrical outlet.
CAUTION
Some expansion boxes are restricted to either 110 Vac or 220
Vac operation. Make sure the voltage requirement of any
expansion box is compatible with the supply voltage. The
RRD40 expansion box has a switch for selecting the power
input voltage.
• Turn on all expansion boxes before you turn on your system unit.
This step ensures that the device in each expansion box is ready
for use, and that the system firmware includes the device in its
configuration.
