SCSI Backplane Daughter Card
NOTE:
Your system supports two- or five-drive configurations. The two-drive configuration is supported with the 1 x 5
backplane configuration, and the five-drive configuration is supported with the 2 x 3 backplane configuration.
Upgrading to a five-drive configuration requires that you add a SCSI backplane daughter card.
To operate the SCSI backplane in a split backplane configuration, you must install a daughter card. In a split backplane
configuration, the five hard-drive bays are arranged in one group of two drives and another group of three drives. This
configuration is referred to as a 2 x 3 split backplane configuration.
