To use SCSI devices in your Dell computer, you must have a SCSI host adapter card, which comes with its own SCSI cable. This cable can be used to attach a variety of SCSI devices (hard-disk drives, tape drives, and so on). The SCSI host adapter config- ures the devices attached to it as one subsystem—not as independent devices.

Although SCSI devices are installed essentially the same way as other devices, their configuration requirements are different.

For details on configuring your SCSI subsystem, refer to the documentation that came with your SCSI devices and/or your host adapter card. The following sub- sections offer some general guidelines.

6&6,￿,'￿1XPEHUV

Each device attached to a SCSI host adapter card, as well as the card itself, must have a unique SCSI identification (ID) number from 0 to 7. When SCSI devices are shipped from Dell, the default SCSI ID numbers are assigned as follows:

‡

‡

‡

‡

A SCSI host adapter card is configured as SCSI ID 7.

A SCSI tape drive or digital audio tape (DAT) drive is configured as SCSI ID 6.

A SCSI CD-ROM drive is configured as SCSI ID 5.

SCSI hard-disk drives are usually configured as SCSI ID 0. (The drive used to boot your system should always be configured as SCSI ID 0.)

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.
