SCSI Power Cables
SCSI power cables should be routed in such a way that they do not block
the airflow through the chassis. There is a 4-pin connector for the power
cables. Connect the connector to the SCA SCSI backplane as noted in Step
3 ("Configuring the hot-plug SCSI drives").
SCA Backplane
The SCSI drives plug into a SAF-TE compliant SCA backplane that provide
power and bus termination. A RAID controller can be used with the SCA
backplane to provide data security.
have RAID support to enable the hot-swap capability of the SCSI drives. All
the jumpers on the SCA backplane are preset and should not be changed.
See Figure 6-6.
