Forming of the SCSI cable
To connect a disk array controller, use the SCSI cable connected to the system board. In
this case, the SCSI cable needs to be formed. The following shows the cable forming at
shipment and how to form the SCSI cable when it is connected to the disk array
controller. (The solid lines indicate lines for valley fold, and the broken lines indicate
lines for mountain fold.)

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 system 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 system 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.
