Introduction
The Adaptec®AAA™-131CA PCI-to-Wide UltraSCSI Array Adapter
provides powerful disk array support in PCI Windows NT personal
workstations. The AAA-131CA is a single-channel, half-size PCI
array adapter, with 50-pin and 68-pin internal connectors and a
68-pin external connector.
This Installation and Hardware Guide explains how to initially install
the AAA-131CA adapter, create the first array, and then install the
supporting software. The Array1000™CA Family Array Management
Guide, which is also included with your array adapter, explains how
to use the supporting software to create and manage additional
arrays.
System Requirements
The minimum system requirements for the AAA-131CA are
■PCI-based 90-MHz Pentium or equivalent motherboard with
PCI-to-PCI bridge support
■An available half-length, unobstructed PCI slot that supports
Bus Mastering

■A standard 72-pin, 16-MByte, Fast-page mode 70-ns or faster
SIMM (non-EDO). (See the Adaptec Web Site at
http://www.adaptec.com/RAID
for a list of approved SIMMs
and vendors.)

Installing the AAA-131CA Adapter and Connecting SCSI Devices
Installing SIMM Memory
Before you can use the AAA-131CA adapter, the SIMM memory
socket must be populated with a standard 72-pin 16-MByte Fast-
page mode SIMM, as shown in Figure 2-2. (The SIMM may already
be installed in the socket.) Visit the Adaptec Web Site at
http://
www.adaptec.com/RAID
for a list of approved SIMMs and vendors.
Installing the AAA-131CA Array Adapter
Follow these steps to install the AAA-131CA adapter:
Note:
If you are installing the AAA-131CA adapter in an
existing system, back up all data before continuing with
installation. You can restore this data after you reconnect your
devices and your create your array(s).
1
Turn OFF power to the computer and disconnect the power
cord.
2
Remove the cover from the computer case. (If necessary, refer
to the instructions in your computer documentation.)
3
Locate an unused, unobstructed, 5-volt PCI expansion slot that
supports bus mastering. Unscrew and remove the expansion
slot bracket that covers the card-slot opening.

Insert the AAA-131CA adapter in the PCI slot, as shown in Fig-
ure 2-3. Press down firmly so that the PCI bus contacts are
securely seated in the slot. Secure the adapter bracket with the
screw you removed in Step 3.

Installing the AAA-131CA Adapter and Connecting SCSI Devices
Connecting the LED Activity Indicator
(Optional) An LED on the front panel of most computers lights to
indicate non-SCSI hard disk activity. If you want the LED to light
whenever there is activity on the AAA-131CA adapter instead, you
must disconnect the LED cable from the motherboard and connect it
to the LED connector on the AAA-131CA adapter. If the LED has a
two-position cable, connect the cable to pins 1 and 2 of the LED con-
nector, as shown in Figure 2-4.
Note:
If you are using non-SCSI disk drives (e.g., IDE), the
LED will no longer indicate activity on these drives when
you connect the LED cable to the AAA-131CA adapter.

AAA-131CA Installation and Hardware Guide
Connecting SCSI Devices
The AAA-131CA adapter supports both internal and external SCSI
devices. Up to 15 SCSI devices can be supported on each SCSI chan-
nel—either 16-bit devices alone or a combination of 16-bit and up to
seven 8-bit devices.
Note:
If you are installing your SCSI devices inside an exter-
nal array enclosure, see Connecting External SCSI Array
Enclosures (Storage Subsystems) on page 2-11.
Choosing SCSI Cables
To connect your SCSI devices, make sure you have the appropriate
cable and connectors as described in the following table (see Installa-
tion Hints for Connecting SCSI Devices on page 2-12 as well as Appen-
dix D, Obtaining SCSI Cables and Converters for additional information
on cabling SCSI devices):
1
Use only high-quality external cables with a single-ended impedance range of 80-110 ohms.
To Install… You WIll Need…
8-bit Internal SCSI Devices • A 50-pin Internal SCSI cable with enough connectors
to accommodate all of your internal SCSI devices.
8-bit External SCSI Devices • A 68-pin to 50-pin external converter.
• A 50-pin Ultra external SCSI cable.
16-bit Internal SCSI Devices • A 68-pin Ultra Wide internal SCSI cable with enough
connectors for all of your internal SCSI devices.
16-bit External SCSI Devices

• A 68-pin Ultra Wide External SCSI cable for each
device.
16-bit External Array
Enclosure

Installing the AAA-131CA Adapter and Connecting SCSI Devices
Connecting Internal SCSI Devices
Follow these steps to connect internal SCSI devices:
1
Prepare each SCSI device for installation:
– Make sure each device (internal and external) is assigned a
unique SCSI ID number from 0 to 15—no duplicate IDs are
permitted on a channel. Do not assign SCSI ID 7, because
each SCSI channel uses this ID by default. (See SCSI ID
Numbers on page 2-13 for additional information.)
– Install (or enable) the terminators on the internal device
you are attaching to the end of the cable only. (See SCSI Ter-
mination on page 2-14 for additional information.)
2
Install and mount each internal SCSI device in an available
drive bay inside your computer. (Refer to your computer and
device documentation for instructions.)
3
If you are connecting 8-bit internal SCSI devices, attach one
end of the 50-pin cable to the 50-pin internal SCSI connector on
the AAA-131CA adapter. If you are connecting 16-bit internal
SCSI devices, attach one end of the 68-pin cable to the 68-pin
internal SCSI connector on the AAA-131CA adapter.
Figure 2-5. Attaching 68-pin Internal Ribbon Cable

2-8
AAA-131CA Installation and Hardware Guide
4
Attach the remaining connectors on the cable to the remaining
internal devices.
5
Connect an available DC power cable (from your computer’s
power supply) to the power input connector on each SCSI
device.
Connecting External SCSI Devices
For each external SCSI device, you must obtain a high-quality external
cable with a single-ended impedance range of 80-110 ohms. For addi-
tional information on cabling SCSI devices, see Installation Hints for
Connecting SCSI Devices on page 2-12. Follow these steps to connect
external SCSI devices:
1
Make sure each device (internal and external) is assigned a
unique SCSI ID number from 0 to 15—no duplicate IDs are
permitted on a channel. (See SCSI ID Numbers on page 2-13 for
additional information.)
2
Attach one end of the 68-pin cable to the 68-pin Ultra Wide
external SCSI connector on the adapter (shown in Figure 2-6.)
