6-7
Always route SCSI power and ribbon cables so that
they do not impede airflow or interfere with running
fans.
3. SCSI backplane:
All seven SCSI drives plug into the SCSI backplane (p/n SCA742), which
provides dual channel, Ultra320 operation. There are no jumpers on the
SCSI backplane. Ribbon cables from JA1/JA2 on the motherboard should
be connected to the LVD1/LVD2 connectors on the SCSI backplane (SCSI
channels A/B). There are also two power connectors on the backplane -
both should be connected. See Figure 6-6 for the locations of backplane
connectors - the reverse side of the backplane has seven connectors
that the SCSI drives plug into when inserted with a SCSI drive carrier.
See Figure 6-1 for channel and drive number configuration. You cannot
cascade the SCSI backplane.

Important: Regardless of how many SCSI hard drives
are installed, all seven SCSI drive carriers must remain
in the drive bays to promote proper airflow.
