„SCSI cable connection

To use the internal hard disk drives in a disk array configuration, disconnect the SCSI cable from the SCSI connector on the mother board, and connect it to the connector of the disk array controller board.

IMPORTANT:

„To switch the internal hard disk drives into a disk array configuration by connecting a disk array controller to the full-height riser card, connect the cable before installing the riser card on the mother board.

„Some disk array controller boards have more than one channel (connector). They may have connectors for internal connection and external connection. However, the connectors may be under exclusive specification in consideration of the internal connection of the disk array controller board. Make sure that each connector (channel) is for internal connection or external connection. For the connectors and channels, see the manual provided with the disk array controller board.
