The Adaptec SCSI Card 29320LP enables you to connect up to 15
SCSI devices—such as very large arrays of high-performance
hard disk drives, external storage subsystems, Ultra320/160 hard
disk drives, scanners, and CD-ROM drives—to any Intel-based
computer with 64- or 32-bit PCI/PCI-X expansion slots.
The Adaptec SCSI Card 29320LP is a single channel SCSI card
with a maximum throughput of 320 MB/sec. You can connect
Ultra320/160 and Ultra2 SCSI devices to the internal 68-pin Low
Voltage Differential/Single-Ended (LVD/SE) connector and the
external very high-density cable interconnect (VHDCI) connector.
Although the Adaptec SCSI Card 29320LP is a 64-bit PCI/PCI-X
card, it also works in a 32-bit PCI slot. When installed in a 32-bit
PCI slot, the card automatically runs in the slower 32-bit mode.
This installation guide explains how to:
•Install the Adaptec SCSI Card 29320LP
•Set up SCSI devices
•Connect SCSI devices
INTRODUCTION
If you connect single-ended Wide Ultra/Ultra SCSI
devices to the same SCSI channel as Ultra320/160 and Ultra2
SCSI devices, the data transfer rate for the Ultra320/160 and
Ultra2 SCSI devices will drop to Ultra SCSI performance
levels.

Discharge any static electricity build-up before handling your
SCSI card by touching a grounded metal object (like the exposed
metal parts on the back of your computer).
After you turn off your computer and unplug the power cord,
remove the cover from the computer.
Locate an unused 64-bit PCI/PCI-X expansion slot and remove
the expansion slot cover. If the computer does not have a 64-bit
slot, you can install the card in a 32-bit PCI slot. The Adaptec
SCSI Card 29320LP supports both 5V and 3.3V 64-bit slots. (The
expansion slot must be compliant with PCI Rev. 2.1 or PCI-X
Rev. 1.0 and must support Bus Mastering.) Save the slot cover
screw for use in Step 4.

Computers may have vertical or horizontal expansion slots. Refer
to your computer manual to locate the PCI/PCI-X slots. If your
computer is a tower model, lay it on its side to allow for easier
installation of the Adaptec SCSI Card 29320LP.
Insert the Adaptec SCSI Card 29320LP in the 64-bit (or 32-bit) PCI
or PCI-X expansion slot; press down firmly until the card clicks
into place, then replace the slot cover screw. When installed
properly, the card should appear level with the expansion slot, as
shown below.
Be careful when inserting the Adaptec SCSI Card
29320LP in a PCI slot. Some 32-bit slots will not accommodate
it, and the card may break if you force it into the slot.

There are several things you may need to do to your SCSI devices
before you connect them to the Adaptec SCSI Card 29320LP:
•Check the SCSI IDs
•Set the termination
•Connect the power cables
Since setup can vary from device to device, always refer to the
device’s documentation for specific instructions.
Folowing are some guidelines for setting SCSI IDs and
termination on your devices.
Check the SCSI IDs
The Adaptec SCSI Card 29320LP and each device you connect to
it must have a unique SCSI ID number ranging from 0 to 15. No
two devices on the SCSI channel can have the same SCSI ID.
The Adaptec SCSI Card 29320LP is preset to ID 7 and should not
be changed. If you boot from a SCSI hard disk, make sure the
hard disk SCSI ID is set to 0. (Most SCSI hard disks are preset to
SCSI ID 0 at the factory.) The SCSI IDs for internal devices are
usually set with jumpers; SCSI IDs for external devices are
usually set with a switch on the back of the device.
Terminate the Ends
To ensure reliable communication on the SCSI bus, the device at
the end of each cable, or the end of the cable itself, must have a
terminator installed (or enabled). Terminators must be removed,
or termination must be disabled, on devices between the ends of
each cable.
SETTING UPSCSI DEVICES
When connecting Ultra320/160 or Ultra2 SCSI devices,
the SCSI bus must be terminated either on the end of the cable
(with a permanent terminator) or with a separate terminating
connector. Ultra SCSI and earlier single-ended devices can
terminate the bus directly from the device. If you use an Ultra
SCSI terminator on an LVD Ultra320/160 and Ultra2 SCSI bus,
the SCSI devices will not operate properly. For this reason be
sure that you have the necessary Ultra320/160 or Ultra2 cable
and terminator before installing the Ultra320/160 SCSI
devices.

You can connect a total of 15 SCSI devices to the Adaptec SCSI
Card 29320LP. Before connecting devices, be sure to review
Setting Up SCSI Devices on page 4.
Connecting Internal Ultra320/160 and Ultra2 Devices
A special 68-pin internal LVD cable is needed to connect internal
Ultra320/160 or Ultra2 SCSI devices. If your cables are not
marked, you can identify most LVD cables as having twisted
pairs ofthe flat ribbon cable between the device connectors. Some
cables are laminated so that they lay flat. Internal LVD cables
usually have a terminator built into the end of the cable.
The Adaptec SCSI Card 29320LP has one internal LVD/SE
connector to which you can connect internal SCSI devices.
Follow these steps to connect your internal Ultra320/160 and
Ultra2 devices:
Locate a 68-pin internal LVD SCSI cable, which may have either
twisted wires or flat wires, as shown here.
CONNECTING SCSI DEVICES
Adaptec recommends that you keep your Ultra320/160
and Ultra2 SCSI devices separate from your Ultra SCSI
devices. If you connect a legacy SCSI hard disk drive to the
Adaptec SCSI Card 29320LP LVD/SE connectors, the
Ultra320/Ultra160 and Ultra2 SCSI hard disk drives will slow
to Ultra SCSI performance levels.

Plug the nonterminated end of the cable(s) to the internal

Plug the internal Ultra320/160 and Ultra2 SCSI devices to the
other cable connectors, starting with the connector at the
terminated end of the cable.

STEP 3
Internal Ultra320/160 and Ultra2 SCSI devices come
from the factory with termination disabled and cannot be
changed. Proper termination is provided by the terminator at
the end of the LVD SCSI cable.

Connect a power cable from your computer’s internal power
supply to each internal SCSI device.
Connecting External SCSI Devices
You can connect external Ultra320/160 and Ultra2 SCSI devices
to the 68-pin external LVD/VHDCI connector. Each external
device will require a 68-pin VHDCI external LVD SCSI cable.
Follow these steps to connect your external SCSI devices:
Connect one end of an external SCSI cable to the external
Ultra320/160 connector on the Adaptec SCSI Card 29320LP.
Connect the other end of the cable to a SCSI connector on the
back of an external device. If you are installing only one external
device, terminate the device and skip to Step 4.

Connect the other external SCSI devices by linking each device to
the previous one, as shown below. Terminate only the device at
the end of the chain.
Connect power cables to all external device(s) and to the
computer.
The last SCSI device on the end of each SCSI bus cable must be
terminated, and termination must be disabled for all other devices
in the middle of the cables. Ultra320/160 and Ultra2 SCSI devices
are automatically unterminated, but Ultra SCSI and Fast/Wide
SCSI devices do have termination that you must check. For more
information, refer to the documentation for each SCSI device.
If you are using external Ultra2 or Ultra320/160 devices, be sure
to use anLVD terminator to terminate the last device in the chain.
If you use a single-ended, active terminator (sometimes called an
Ultra terminator) the SCSI devices will not operate properly.

If you have any problems while installing the Adaptec SCSI Card
29320LP, check the following items first:
•Are all SCSI devices powered on?
•Are all SCSI cables and power cables properly connected?
•Does each device on each SCSI bus have a unique SCSI ID?
•Does the total SCSI cable length exceed the maximum
allowable length?
•Is the SCSI bus properly terminated?
If you are still unable to resolve a problem, contact the system
manufacturer for help.
Preloaded Adaptec Drivers
If the Adaptec SCSI Card 29320LP was included as part of a
computer system you purchased, the system already has the
appropriate Adaptec driver preinstalled by the computer
manufacturer. No further action is necessary to install the driver.
Embedded Adaptec Drivers
Some operating systems have embedded driver support for the
Adaptec SCSI Card 29320LP. To determine if the card is
supported by the operating system you are using, read the
operating system manual or contact the operating system vendor
for information.
TROUBLESHOOTING
ADAPTEC SCSI CARD DRIVER SOFTWARE
To use the Adaptec SCSI Card 29320LP, driver software
must be installed for your operating system. Installation of the
driver software varies depending on how and where you
purchased the Adaptec SCSI Card 29320LP.
