SCSI Device Installation Guidelines

This section describes how to configure and install SCSI devices in your
computer. To install a SCSI device, you can use one or both of the following
SCSI controllers:
• The SCSI connector on the system board. To locate the SCSI system
board connector, see
Label."
NOTE:
The system board SCSI controller will support hard drives only.
Do not connect CD or DVD drives, tape drives, DAT drives, and so on. An
add-in SCSI controller can be installed in your computer for this purpose.
• A SCSI controller card installed in your computer.
SCSI ID Numbers
Internal SCSI devices must have a unique SCSI ID number from 0 to 15. If
you are using the SCSI connector on the system board and a SCSI
controller card installed in your computer, you will have two separate SCSI
buses operating. Each SCSI bus will have a set of SCSI ID numbers from 0
to 15.
When SCSI devices are shipped from Dell, the default SCSI ID numbers
for are assigned as follows:

NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or
that devices be attached to the cable in order by ID number.
