Use of internal hard disk drives in a disk array configuration
To use the internal hard disk drives in a disk array configuration in the server containing a disk
array controller board, reconnect the SCSI cables and LED cables on the system board.
The internal hard disk drive interface is connected to the SCSI connector on the system board at
shipment.
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.)
