Installing the eXtremeRAID 2000 on the System Board
4 eXtremeRAID 2000 Quick Installation Guide
If LVD-capable drives and single-ended drives are
installed on the same channel, both drives types will
operate as single-ended drives, and the bus length will
be limited to the single-ended bus length.
4. Disable termination for each SCSI disk drive. For information on how
to do this, refer to the disk drive documentation.
5. Enable termination power for each SCSI disk drive. For information on
how to do this, refer to the disk drive documentation.
6. Set the SCSI ID for each external disk drive to a unique address
between 0 and 15, but do not use address 7 (reserved for the controller).
☛
Note
Do not duplicate SCSI IDs used by internal drives
designated for the same channel.
For information on how to do this, refer to the disk drive
documentation.
7. Insert the disk drives into the drive cabinet. For more information, see
the documentation that accompanied the enclosure.
8. Select from the following for each group of SCSI drives:
• If the drives are in the same cabinet as the controller, connect the
SCSI drives to the SCSI cable and connect the cable to a channel on
the controller. If the last device is not terminated, attach a terminator
to the last connector of the SCSI cable.
• If the drives are in an external cabinet, connect one end of a wide,
round, 68-pin Very High Density Connector Interface (VHDCI)
cable to the eXtremeRAID 2000 controller and the other end to the
external drive cabinet.
External drive cabinets usually have termination built into the end of
the SCSI bus. If not, attach a terminator to the last connector of the
SCSI cable. If you are unsure, check the cabinet documentation.
☛
Note
The eXtremeRAID 2000 controller automatically
determines whether or not its own on-board
termination is required, and automatically enables or
