nstalling 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 Figure 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 backplane
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.
