Installing Your Controller
Set the SCSI ID of each SCSI device attached to the controller to a
unique ID number between 0 and 6. The Adaptec RAID controller
is set to ID 7 by default (most SCSI controllers use ID 7). Wide SCSI
devices can also use SCSI IDs 8 through 15. SCSI IDs can only be
duplicated on the same controller if the devices using the same ID
are not attached to the same bus.
If necessary, the Adaptec ZCR controller ID can be changed to any
ID from 0 through 7. Use SMOR or the Configure Host Bus
Adapter
window in Adaptec Storage Management to change the controller SCSI ID.
Note: Changing the controller ID is not recommended. You
should leave the Adaptec ZCR controller set at SCSI ID 7.
SCSI Termination
The basics of termination are:
■ Enable termination on the devices on each physical end of a
SCSI cable. Depending upon how you configure your system,
you would either:
■ Enable termination on two SCSI peripheral devices, or
■ Enable termination on the SCSI controller and one
peripheral SCSI device.
■ If using both SCSI channels, terminate each channel separately.
Note: In some cases, the termination settings may need to be
set using your motherboard’s SCSI BIOS. This would be
accomplished by removing the ZCR controller, setting the
termination as desired, and replacing the controller.
Any termination settings made or recommended in this guide
may be superseded by settings or controls designed into the
motherboard. Please review this chapter along with the
contents of your motherboard guide for a better
understanding of the settings necessary for your combination.
