SCSI Device Installation Guidelines
This section describes how to configure and install SCSI devices in your computer.
SCSI ID Numbers
Internal SCSI devices must have a unique SCSI ID number from 0 to 15. Each SCSI bus has a set of SCSI ID numbers from 0
to 15.
When SCSI devices are shipped from the factory, the default SCSI ID numbers are assigned as follows:
System Board Controller Controller Card
Device ID Device ID
Controller 7 Controller 7
Boot hard drive 0 Boot hard drive 0
CD or DVD drive 5
tape or DAT drive 6
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. If two or more devices use the same ID, your computer may hang during POST and in SCSI BIOS.
SCSI devices installed by Dell are configured correctly during the manufacturing process. You do not need to set the SCSI ID
for these SCSI devices.
If you attach additional optional SCSI devices, see the documentation for each device for information about setting the
appropriate SCSI ID number.
NOTICE: Dell recommends that you use only SCSI cables purchased from Dell. Cables purchased elsewhere are not
guaranteed to work with Dell computers.
