Installing SCSI Hard-Disk Drives in the Internal Drive Bays

SCSI hard-disk drives are supplied by Dell in special drive carriers that fit in the internal drive bays (see Fig- ure 10-2). The printed circuit board at the back of the drive carrier acts as an interface between the SCSI hard- disk drive and the SCSI backplane board.

NOTE: Dell recommends that you use only drives that Dell has tested and approved for use with the SCSI back- plane board.

SCSI Hard-Disk Drive Configuration

The SCSI backplane board provides termination for the SCSI bus. None of the drives connected to the SCSI backplane board should have their termination enabled. All SCSI ID numbers for the drives are set by the SCSI backplane board.

Removing and Installing a SCSI Hard-Disk Drive

The following subsections describe how to remove or install SCSI hard-disk drive carriers in the computer’s internal drive bays.
