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. The operating system you use must
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.
Figure 6-6. SCA Backplane
Use caution when working around the SCA backplane.
Do not touch the backplane with any metal objects
and make sure no ribbon cables touch the backplane
or obstruct the holes, which aid in proper airflow.
