Connecting the Drives to the StorPoint CD
A single StorPoint CD can service up to 7, 8 or 14 CD/DVD-ROM drives or up
to six or seven hard disks, depending on model.
• SCSI Server - The SCSI bus allows 7 drives to be connected to the
StorPoint CD. Each unit on the SCSI bus must have a unique SCSI
address. To work properly, the bus must be electrically terminated at both
ends.
If you want to use the hard disk caching facility, you must connect 1 to 6
hard disk units to the StorPoint CD. The StorPoint CD will automatically
format the hard disks detected on the SCSI bus.
• IDE Server - The IDE bus allows 8 drives to be connected to the StorPoint
CD. Each unit on the IDE bus must be assigned as Master or Slave.
If you want to use the hard disk caching facility, you must connect 1 to 7
hard disk units to the StorPoint CD. The StorPoint CD will automatically
format the hard disks detected on the IDE bus.
Caution!
❏ Always make sure that power is not connected to the StorPoint CD or any
of the drives when making changes to the SCSI chain. The SCSI bus or IDE
bus may become damaged if you connect or disconnect any units when the
power is on.
Dual SCSI Version It is recommended that the dual SCSI version of StorPoint CD is installed in a
14 bay tower, i.e. all the drives are housed in the same enclosure with the SCSI
cables built-in.
Note:
❏ However, if you are using two separate towers, we recommend that the cable
from the StorPoint CD to the second tower complies with the following
maximum cable length requirements:
• The cable from the StorPoint CD to the connector leaving the first
tower should not exceed 60 cm.
• The cable connecting the two towers should not exceed 50 cm.
Connecting the
SCSI Drives
To connect the SCSI drives to the StorPoint CD, follow these steps:
1. Connect the SCSI cable to the SCSI connector on the StorPoint CD.
2. Connect the SCSI cable to the drive(s).
3. Set a unique SCSI address 0 through 6 for each of the connected drives. The
dual SCSI version has two separate buses with addresses 0 through 6 available
on each. Refer to the drive documentation for instructions on how to set the
SCSI address on your drives.
Note:
❏ The SCSI address of the StorPoint CD is 7, and cannot be changed.
