viii PCI SCSI-2 Fast/Wide Single-Ended Adapter Installation Guide

Chapter 1. Overview
The PCI SCSI-2 Fast/Wide Single-Ended Adapter enables you to use internal and
external small system unit system interface (SCSI) devices with system units
containing a Peripheral Component Interconnect (PCI) bus. The adapter conforms to
the American National Standards Institute (ANSI) SCSI-2 standard and the PCI local
specification, revision 2.0.
The PCI SCSI-2 Fast/Wide Single-Ended Adapter supports fast and wide SCSI
synchronous data rates up to 10 MHz. Wide (16-bit) SCSI supports a maximum
transfer rate of 20 MB (20,000,000 bytes) per second. Narrow (8-bit) SCSI supports
a maximum transfer rate of 10 MB per second.
The PCI SCSI-2 Fast/Wide Single-Ended Adapter allows the connection of internal
and external SCSI devices.
SCSI Connectors
There are three SCSI connectors on the adapter:
External connector:
– J2 68-pin SCSI standard connector.
Internal Connectors:
– J3 68-pin high-density SCSI standard connector for 16-bit attachment
– J4 50-pin (2 by 25) SCSI standard connector for 8-bit attachment.

Chapter 1. Overview 1-1

The adapter provides built-in SCSI terminators that are automatically enabled or
disabled depending on what cables are attached.
Handling the Adapter
Attention: Static electricity may damage your equipment. Leave the adapter in the
static-protective bag until you are ready to install the adapter.
1-2 PCI SCSI-2 Fast/Wide Single-Ended Adapter Installation Guide

Chapter 2. Preparing for Installation
The installation process consists of:
Taking an inventory of all pieces necessary for installation
Determining your cable needs
Installing the adapter
Installing device drivers
Inventory
To install the PCI SCSI-2 Fast/Wide Single-Ended Adapter, you need:
The adapter
The documentation that came with your system unit
A flat-blade screwdriver.
You also need the following items to connect SCSI devices to the adapter:
The documentation that came with your SCSI devices
External cables
Internal cables
A SCSI terminator.
Determining Cable Needs
External SCSI devices have a variety of connectors. Ensure that you have cables
with the appropriate connectors for each external device in your planned SCSI chain.
You can attach external wide (16-bit) devices or narrow (8-bit) devices to the adapter
with the proper cable. In both cases, the cable end that attaches to the adapter is a
68-pin connector. The device end varies with the type of device you are attaching.
Internal devices typically attach to a cable with one or more connectors allowing you
to attach devices to the cable. You can use a wide or narrow SCSI internal cable.
The wide cable attaches to the 68-pin internal connector, J3. The narrow cable
attaches to the 50-pin connector, J4 (see Figure 1-1 on page 1-1).
Internal Cabling
If you plan to use internal SCSI devices in your system, you must first obtain the
necessary cables for your system unit. Install the cables according to the
instructions provided by your system unit's instructions.
Chapter 2. Preparing for Installation 2-1

There must be a SCSI terminator on the end of this cable. Some terminators are
plugged into the last position of the internal cable. Some terminators are built onto
the cable and can not be removed. Some terminators are built into the SCSI device.
Still others can be built on to a backplane within the system unit. You need to
understand your internal installation, in detail, in order to determine where and how
to attach the internal SCSI terminator.
Important: You can attach an internal cable to only one of the adapter's two internal
connectors at any time.
External Cabling
You can attach either narrow (8-bit) or wide (16-bit) SCSI devices to the external
68-pin connector.
You must have the proper SCSI cable to correctly attach a device. Narrow devices
use a cable with a 50-pin connector on the device end and a 68-pin connector on the
adapter end. Wide devices use a cable with a 68-pin connector on both ends.
SCSI specifications limit total cable length to 6 meters (approximately 20 feet). Total
cable length of the SCSI chain includes internal and external cabling.
If you use a fast synchronous device, such as a narrow SCSI disk that can transfer
up to 10 MB/second of data or a wide SCSI disk that can transfer up to 20
MB/second of data, the maximum cable length is limited to 3 meters (approximately
10 feet).
For more information on connecting SCSI devices to the adapter, see Appendix A,
“Connecting SCSI Devices to the Adapter” on page A-1. Refer to Appendix B,
“Cable Choices” on page B-1 for more information on cables choices.
2-2 PCI SCSI-2 Fast/Wide Single-Ended Adapter Installation Guide

Chapter 3. Installing the Adapter
Refer to Appendix C, “Jumper Settings and Multi-Adapter Configurations” on
page C-1 to determine whether you need to change the default jumper settings on
the adapter.
If you need to set the J7 jumpers on the adapter as described in Appendix C,
“Jumper Settings and Multi-Adapter Configurations” on page C-1, do so now.
Remove Covers
Refer to the documentation that came with your system unit for direction on shutting
down your system and removing the system unit covers.

expansion slots.
After the adapter is installed, replace your system unit covers as described in the
system unit documentation.
Connecting Internal Devices and Installing the Adapter
Refer to the documentation provided with your system unit to remove the system unit
covers and to install an internal SCSI device.
Attention: Static electricity may damage your equipment. Leave the adapter in the
static-protective bag until you are ready to install the adapter.
1. Attach the appropriate narrow or wide (8-bit or 16-bit) cable to the device and
then install the device.
2. Ensure that there is a SCSI terminator on the end of the cable or that a
terminator is supplied by the last SCSI device on the internal chain. If the
terminator is supplied by the internal SCSI device, the internal SCSI device must
be placed on the internal cable location farthest from the adapter.
3. Connect the adapter end of the internal cable to the correct internal connector on
the PCI SCSI-2 Fast/Wide Single-Ended Adapter. Use either the 50-pin internal
connector, J4, or the internal 68-pin connector, J3.
All the connectors are built so they can only be plugged in one way.

4. Install the PCI SCSI-2 Fast/Wide Single-Ended Adapter into any available PCI
slot.
After all your internal SCSI devices and the adapter are installed, replace your
system unit covers as described in the system unit documentation.
Connecting External SCSI Devices
At this time the adapter should be installed and the system covers back on.
To connect external devices:
1. Connect the 68-pin connector to the external port (J2). Use the fastening screws
on the cable connector to securely attach the connector to the adapter.
2. Connect the other end of the cable to your SCSI device.
3. If necessary, connect additional cables to additional SCSI devices.
4. When all devices are connected, ensure that a SCSI terminator is attached to the
last device.

Appendix A. Connecting SCSI Devices to the Adapter
Planning Your SCSI Device Layout
SCSI devices are attached to a SCSI adapter in a chain. Devices in the chain can
be internal (inside your system unit) or external (connected outside your system unit).
If you are connecting more than one SCSI device, it is important that you plan the
layout of your SCSI chain.
Note: At each end of the SCSI chain, a terminator is required.
Figure A-1. SCSI Chain with Internal and External Devices
Term is the SCSI terminator on the last device or the end of the cable.
Setting SCSI Addresses
Each SCSI device requires a unique SCSI address. The address is a number from 6
through 0 for narrow devices or from 6 through 0 and 15 through 8 for wide devices.
If two SCSI devices have the same address, your system unit will not function
properly. SCSI address 7 is reserved for the adapter, so additional SCSI devices can
be set to addresses 6 through 0 and 15 through 8.
Appendix A. Connecting SCSI Devices to the Adapter A-1

Determining Current SCSI Addresses
This section provides directions for installing the PCI SCSI-2 Fast/Wide Single-Ended
Adapter.
Manufacturers use many different methods to set SCSI addresses, including
jumpers, dual inline package (DIP) switches, push buttons, or dials. If your SCSI
device is new, check the manual that shipped with the device to see if it specifies a
default SCSI address. If one is not specified, check how SCSI addresses are set,
then check the device itself for the current SCSI address. Be sure to maintain a list
of all your SCSI addresses for future reference (your system unit documentation may
provide a table where you can record them).
Important: Before you set the SCSI address, you must first determine which
addresses are available; that is, not already in use by other SCSI devices and
adpaters installed in your system. Each SCSI device or adapter must have a unique
address. To determine the SCSI addresses of the devices/adapters already
installed, enter the following command:
lsdev -Cs scsi
This command returns the following information:
Column 1: device name (for example, scsið)
Column 2: device status (for example, Available)
Column 3: SCSI information (the format is: nn-nn-nn-s,b)
Column 4: device type (for example, CD-ROM drive, 2.3GB tape drive, etc.)
The s in the nn-nn-nn returned in Column 3 is the SCSI address of the associated
device. The b is the SCSI bus number for that device.
Record the names and SCSI addresses of your installed SCSI devices in Table A-1
on page A-3. This helps you select non-conflicting addresses for any new devices
you add.
Planning SCSI Addresses
Make sure no two SCSI devices have the same address, and that no device uses
the SCSI address 7, which is reserved for the adapter. Note: SCSI addresses are
not in sequential order from highest to lowest priority. Refer to Table A-1 on page
A-3 for the priority associated with each SCSI address.
