Introduction
NOTE: This installation guide applies to the following QLogic host adapter boards,
collectively referred to as the QLA12160 board unless otherwise noted:
I QLA12160/33 (DC8110402-06)
I QLA12160/66 (DC8110402-07)
The QLA12160 board (wide, low voltage differential [LVD]), dual port,
Ultra3, 64-bit PCI) contains the ISP12160A/33 or ISP12160A/66 chip.
1.1
Product Description
The QLA12160 board is an intelligent, high-performance, DMA bus master SCSI
host adapter designed for high-end systems. The intelligence and performance are
derived from the ISP chip, making the QLA12160 board a high performance host
processors (SXPs), and a peripheral component interconnect (PCI) local bus
interface in a single-chip solution. The QLA12160 board supports bootable devices
(hard disk drives and CD-ROM drives) and can be used with tape drives and other
SCSI devices. Installation of the QLA12160 board is quick and easy.
The QLA12160 board is for use only with UL listed computers that have detailed
instructions for user installation of accessory cards.
The QLA12160 board is designed to operate with multiple data transfer speeds
under SCSI specifications (see table 1-1).

Features
1 – Introduction
The QLA12160 board supports Ultra, Ultra2, and Ultra3 transfer speeds. The board
can connect computers to other computers or to peripheral devices such as
CD-ROM drives, tape drives, and hard disk drives. SCSI allows connecting the
following numbers and types of devices to a single port by daisy chaining:
I 15 fast, wide SCSI devices
I 15 Ultra2 or Ultra3, LVD SCSI devices
I 6 Ultra SCSI devices (QLA12160 board in single-ended mode)
A daisy chain is a series of connections where the first device is connected to the
host adapter board, the second device is connected to the first device, and so on.
A daisy chain can be created either by using a daisy chain cable (one cable with
multiple connectors) or by using multiple cables. Each SCSI device must have a
unique SCSI ID.
Because SCSI allows the computer to use a standard set of commands to
communicate with peripherals, adding a variety of peripherals to your computer
using one host adapter board is easy.

Hardware Installation
2.1
Preinstallation Procedures
Before installing your QLA12160 board, take the time to read this instruction guide.
CAUTION!
I Your computer, the QLA12160 board, and each SCSI device must
be configured properly for optimum performance. Refer to the
appropriate documentation to configure your computer and SCSI
devices.
I Pay particularattention totheSCSI ID assignment. The QLA12160
board is set at the factory for SCSI ID 7. The QLA12160 board
and each SCSI device attached to the board must have
different SCSI IDs.
I The QLA12160 board contains parts that can be damaged by
electrostatic discharge (ESD). Before handling the QLA12160
board, use standard methods to discharge static electricity. Keep
the QLA12160 board in the antistatic bag until you are ready to
installit. Placetheboardonthebagwhenyouexamineorconfigure
it. Retain the bag for future use.
2.2
What You Need for Installation
Before you install the QLA12160 board in your computer, you need the following:
I A screwdriver (usually a Phillips #1)
I One or more of the following cables:
I Internal narrow (68-pin to 50-pin)
I Internal wide (68-pin to 68-pin)
I External narrow (68-pin very high density cable [VHDC] to 50-pin)
I External wide (68-pin VHDC)

Setting the SCSI Termination
Termination for the QLA12160 board is set automatically in most cases. You can
change the termination using the Fast!UTIL software (see section A.2.3).
Termination for the QLA12160 board also can be set using jumpers (see
section B.2).
2.4
SCSI Termination Power
The QLA12160 board supplies termination power to itself and to the SCSI bus. The
circuit is protected by a self-restoring fuse.
2.5
Installing the Device Activity Light
If the SCSI disk is assigned as drive C (boot drive), you can connect the device
activity light on the front panel of the PC to indicate boot drive activity. Connect the

light to the J9 jumper block on the QLA12160 board (pins 1 and 4 are positive). If
your boot drive is an integrated device electronics (IDE) drive or connected to a
different adapter, you can connect an LED to the QLA12160 board jumper blocks
to show activity of devices connected to your QLA12160 board.
2.6
Installation in the Computer
If you changed the termination on the QLA12160 board, double-check the new
setting prior to installation.
Perform the following steps to install the QLA12160 board in your PC:
1. Check the motherboard and make any configuration changes necessary to
accommodate the QLA12160 board.
The QLA12160 board is self-configuring; however, some motherboards
require manual configuration. For example, some systems have a PCI
Device Configuration menu in themotherboard setupBIOS where youmust
enable host adapter boards, bus master slots, and interrupt request (IRQ)
levels. If your motherboard supports triggering, use level triggering for the
QLA12160 board. See the documentation supplied with your computer, or
contactyourcomputerdealertodeterminewhetherornotyourmotherboard
requires configuration.
2. Power down the peripherals, then the computer.
3. Remove the computer cover and save the screws.
4. Choose any PCI bus slot that supports bus mastering. Most motherboards
automatically assign an IRQ level and interrupt line. If your motherboard
does not, you must assign the IRQ level and use interrupt line A for this slot.
NOTE:
I Some motherboards have two kinds of PCI bus slots: master
and slave. The QLA12160 board must be in a PCI bus master
slot. (Some motherboards share PCI bus master slots with
onboard devices; QLA12160 boards do not work in shared
slots.)
I If your board is labeled QLA12160/66, it can run in a 66-MHz
PCI slot.
I QLogic recommends installing the QLA12160/33 in a
33-MHz PCI slot and the QLA12160/66 in a 66-MHz PCI
slot.
I Installing a QLA12160/33 adapter in a 66-MHz PCI slot
forces the entire PCI bus to 33 MHz.
I Installing a QLA12160/66 in a 33-MHz slot does not provide
the board with the performance benefits of a 66-MHz PCI
bus.

slot until it seats firmly.
NOTE: QLA12160 boards are designed with the components on the
opposite side compared with non-PCI boards.
7. Secure the QLA12160 board with the slot cover screw.
8. Install the cable.
I Internal: Connect the cable from the devices to the J3 connector on the
QLA12160 board.
I External: Connect a SCSI cable from the devices to the J1 connector
and/or the J2 connector.
NOTE: If you are attaching an external device, you must provide your own
cable.
9. Carefully reinstallthecomputercover. Insertandtightenthecomputercover

information is helpful when troubleshooting or installing other devices.
If there is no hard disk drive attached to your computer, a ROM BIOS NOT
INSTALLED message is displayed after the device listing.
When the information displayed on your monitor is correct (all installed devices are
listed with the correct SCSI ID, device type, etc.), congratulations! You have
successfully installed the QLA12160 board in your computer.

Installation Help
If your system has an IDE fixed disk device, be sure to program the system BIOS
to point to the appropriate boot drive. If your system does not have an IDE disk
device, the first bootable SCSI disk device configured (the one with the lowest SCSI
ID) is assigned device number 80 and is the boot device.
For a motherboard BIOS that does not support SCSI disk booting, you can use
settings in Fast!UTIL to select the system’s boot device attached to the QLA12160
If the boot device is a disk, see section A.2.5 about selectable boot settings.
SCSI ID numbers must be unique; otherwise, the BIOS list of SCSI devices
displayed onyourmonitoris notcorrect. Forexample, ifyou giveoneofyour devices
the same SCSI ID as the QLA12160 board, that device is listed for all SCSI IDs; or
if you have two devices with the same SCSI ID, only one of the devices is listed. If
the BIOS list is not correct, power down the computer and check the configuration.
Be sure to check the QLA12160 board, which uses SCSI ID 7. If you do not see
If you do not have an IDE drive, set the motherboard BIOS parameters to None or
Not Installed. The ROM BIOS on the SCSI controller automatically configures the
SCSI peripherals.
If the QLA12160 board is on a SCSI bus with any single-ended peripheral device,
for example, a CD-ROM, the QLA12160 board automatically operates as a
single-ended, Ultra device. Consequently, all single-ended device restrictions apply
to the QLA12160 board, even though it is an LVD device (see table 3-1 and
appendix C).

Introduction
This appendix provides detailed configuration information for advanced users who
want to customize the configuration of the QLA12160 board and the connected
devices.
The QLA12160boardis configured at the factory toprovidemaximum performance.
When your board is operating at maximum performance, it may not be 100%
compatible with some older SCSI-1 devices. If you are using a SCSI-1 device, see
section A.5 for more information.
The board can be configured using Fast!UTIL. To access Fast!UTIL, press ALT+Q
during the QLA12160 board BIOS initialization (it may take a few seconds for the
Fast!UTIL menu to appear). If you have more than one QLA12160 board, Fast!UTIL
promptsyoutoselectwhichboardyouwanttoconfigure.Afterchangingthesettings,
Fast!UTIL reboots your system to load the new parameters.
CAUTION! When the configuration settings are incorrect, the QLA12160 board
does not function properly.
The following sections describe the Fast!UTIL options.
A.2
Configuration Settings
The first selection on the Fast!UTIL Options menu is Configuration Settings.
These settings configure SCSI devices and the QLA12160 board to which they are
attached.

I Host adapter BIOS. When this setting is Disabled, the ROM BIOS on the
QLA12160 board is disabled, freeing space in upper memory. The RAM
BIOS and other drivers still recognize the QLA12160 board. Do not disable
this setting when you are booting from a SCSI disk drive attached to the
QLA12160 board. The default is Enabled (ROM BIOS on the QLA12160
board is enabled).
I PCI bus DMA burst. When this setting is Enabled, burst transfers are
performed. When this setting is Disabled, data is transferred in nonburst
mode, with each cycle initiated by a new address phase. The default is
Enabled.
I CDROM Boot. When this setting is Enabled, the ROM BIOS boots from the
attached SCSI CD-ROM when a bootable compact disk is installed. If no
bootable CD-ROM is found, the system boots from the first bootable SCSI
drive. When this setting is disabled, the ROM BIOS does not boot from the
CD-ROM. The default is Disabled.

I Auto. The ROM BIOS automatically configures the QLA12160 board to
match any SCSI device attached to the board and selects optimum
performance. The default is Auto.
I Manual. You can control the configuration settings for each SCSI device
and have the option of running Autoconfigure. See section A.2.4 to have
Fast!UTIL configure the devices.
NOTE: Changing any value can cause performance problems or
incorrect device operation.

I SCSI termination
Termination for the QLA12160 board can be set in one of three ways:
I Automatic (default)
I Manual (through Fast!UTIL)
I Jumpers
NOTE: The last SCSI device on each end of the SCSI bus must be
terminated.
The QLA12160 board is a dual-port host adapter. Each port is a separate
SCSI bus and must be terminated independently. The port one and two
connectors are listed in table A-4.

The following text explains automatic and manual termination. See
section B.2 for jumper termination instructions.
I Auto. SCSI termination requirements are sensed by the board and set
automatically. The default is Auto.
With QLA12160 boards, the Auto setting assumes that port one is at one
end of the SCSI bus and enables termination for port one. If you are
using a single port-one connector, the Auto setting assumes that port
one is at the end of the SCSI bus and enables termination for port one.
If you have devices connected to both port one connectors, the Auto
setting disables termination for port one.
I Enabled. This setting overrides termination requirements sensed by the
board, assumes that the selected port is at one end of the SCSI bus,
and enables termination.
I Disabled. SCSI termination is disabled. This setting overrides
termination requirements sensed by the board. Use this setting when J1,
J2, or J3 is not at one end of the SCSI bus. For example, use this setting
when you have wide devices daisy chained to the QLA12160 J1, J2,
or J3 connector with a single cable and the J1, J2, or J3 connector is not
at the end of the cable.
I HighOnly.Highterminationisenabled.Thissettingoverridestermination

Autoconfigure SCSI Devices
NOTE: You must settheAdapter Configuration settinginHost Adapter Settings
to Manual (see section A.2.1) to use Autoconfigure; otherwise, all changes
made with Autoconfigure are reset when your system is rebooted.
The QLA12160 board is designed to sense and configure the devices connected
to your board. When Adapter Configuration is set to Manual, the Autoconfigure
option allows you to control when the bus is scanned and configured. Select the
Autoconfigure SCSI Devices option from the Configuration Settings menu to
scan devices on the SCSI bus. Set the following options, based on the capabilities
of each device:
I Disconnects
I Enable LUN Support
I Enable PPR
I Enable Device
I Negotiate Wide
I Negotiate Synchronous
I Tagged Queuing
I Sync Period
The settings are displayed in the SCSI Device Settings window. Use the arrow
keys to change settings. See section A.2.2for more information about SCSI Device
Settings and see section A.2.1 for Host Adapter Settings.
If you use Autoconfigure to configure your system, run Fast!UTIL and select
Autoconfigure SCSI Devices after adding or reconfiguring devices attached to the
QLA12160 board.

Using SCSI-1 Devices
The QLA12160 board is configured at the factory with default parameters that
provide maximum performance. When the board is operating at maximum
performance, it may not be 100% compatible with some older SCSI-1 devices.
If the SCSI-1 device attached to the QLA12160 board is not functioning correctly,
you can turn off some high-performance parameters for maximum compatibility.
Follow these steps:
1. When you power up the system, press CTRL+Q to access Fast!UTIL.
2. Select Configuration Settings from the Fast!UTIL Options menu.

SCSI Termination
B.1
Setting the SCSI Termination
The first and last physical SCSI devices on each end of the SCSI bus must be
terminated.
Termination is set automatically through Fast!UTIL (see section A.2.1). The
QLA12160 board offers the additional option of terminating with jumpers (see
section B.2).
Some cables have multiple connectors for connecting several devices to one of the
board’s connectors. If the board uses a connector that is not on either end of the
cable, then the board is not at one end of the SCSI bus and you need to change
the termination setting.
The following sections describe how to set termination for the QLA12160 board.
ThetextandillustrationsdescribemultipleSCSIdevices daisy chained ontoasingle
connector on the board. When daisy chaining narrow and wide SCSI devices,
always have a wide SCSI device at the end of the chain.
NOTE: QLogic recommends using external termination in system configurations
with multiple initiators that share the same SCSI bus (such as in Microsoft
cluster configurations). External termination ensures proper device
operation during power cycles. When external termination cannot be
provided, terminate all host bus adapters using jumpers (see section B.2).
B.2
Termination (Jumpers) for the QLA12160
The QLA12160 board comes from the factory with jumpers on pins 1–2 of J5, J6,
J7, and J8; these settings allow automatic termination (see section A.2.1).
Moving the jumpers on J5 and J6 on the QLA12160 board manually sets the
termination for port one. Moving the jumpers on J7 and J8 on the QLA12160 board
manually sets theterminationforporttwo (seefigure B-1). Settings made with these
jumpers override all Fast!UTIL or automatic termination settings.

The following paragraphs give manual termination instructions.
I Termination disabled. Removing the jumpers from J5 and J6 disables
termination for port one. Use this configuration for wide devices daisy
chained to J1 and J3 with a single cable, or when J1 or J3 is not at the end
of the cable. Removing the jumpers from J7 and J8 disables termination for
port two. Use this configuration for wide devices daisy chained to J2 with a
single cable, and J2 is not at the end of the cable.
I Termination enabled. Putting jumpers on pins 2–3 of J5 and J6 enables
termination for port one. Use this setting when a wide device is connected
to J1 or J3. Putting jumpers on pins 2–3 of J7 and J8 enables termination
for port two. Use this setting for a wide device connected to J2.
I High only. Putting a jumper on pins 2–3 of J5 and removing the jumper from
J6 enables high termination for port one. Use this setting for a wide device
connected to one connector and a narrow device connected to the other.
