AAA-130SA Series Installation and Hardware Guide

Setting Up SCSI Peripherals

Setting up SCSI peripherals before attaching them to the
AAA-13xSA RAID card typically involves setting SCSI IDs and ter-
mination, mounting internal peripherals inside your computer or
external array enclosure, and connecting power cables to each
peripheral. Since setup can vary from peripheral to peripheral,
always refer to the peripheral's documentation for specific instruc-
tions. Below are some guidelines for setting SCSI IDs and termina-
tion on your peripherals. Additional installation hints are also
provided to help you install your peripherals.
Note:
If you refer to the peripheral's documentation for
installation instructions, be sure to return to this document
to continue with installation of the software driver.

Check the SCSI IDs

Each peripheral attached to a SCSI channel on the AAA-13xSA
RAID card, as well as the SCSI channel itself, must be assigned a
unique SCSI ID number from 0 to 15—no duplicate IDs are permit-
ted on a channel. ID numbers don't have to be sequential, as long as
the channel and each peripheral has a different number.
We recommend that you leave each RAID card channel set to
its default setting of SCSI ID 7.
SCSI ID 7 has the highest priority on the channel. The priority
of the remaining IDs, in descending order, is 6 to 0, then 15 to 8.
If you have 8-bit SCSI peripherals, they must use SCSI IDs 0, 1, 2,
3, 4, 5, or 6. (To change the SCSI ID on your hard disk and other
SCSI peripherals, refer to the peripheral's documentation.)
If you wish to use a single SCSI disk drive (instead of an array)
as your boot peripheral, we recommend that you set the SCSI
ID for the peripheral to zero. Most SCSI hard disks come from
the factory preset to ID 0.
The IDs for internal peripherals are usually set with jumpers;
external peripherals are usually set with a switch on the back
of the peripheral.
