The Adaptec SCSI Card 29320 enables you to connect up to 15
Low Voltage Differential (LVD) and/or 15 Single-Ended (SE)
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 29320 has one internal and one external
68-pin LVD/SE connector and two internal SE SCSI connectors
(one 68-pin and one 50-pin).
Although the Adaptec SCSI Card 29320 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 29320
•Set up SCSI devices
•Connect SCSI devices
INTRODUCTION
If you connect Wide Ultra/Ultra SCSI devices to the
same SCSI connectors 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.
Attach only Ultra320/160 and Ultra2 SCSI devices to the
LVD/SE connectors to achieve maximum data transfer rates.

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 29320 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 29320.
Insert the Adaptec SCSI Card 29320 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.
There are several things you may need to do to your SCSI devices
before you connect them to the Adaptec SCSI Card 29320:
•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.
Below are some guidelines for setting SCSI IDs and termination
on your devices.
Be careful when inserting the Adaptec SCSI Card
29320 in a PCI slot. Some 32-bit slots will not accommodate it,
and the card may break if you force it into the slot.

Check the SCSI IDs
The Adaptec SCSI Card 29320 and each device you connect to it
must have a unique SCSI ID number ranging from 0 to 15 on each
channel. No two devices on the same SCSI channel can have the
same SCSI ID.
The Adaptec SCSI Card 29320 is preset to ID 7 for each channel
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.
You can connect a total of up to 15 LVD and/or 15 SE SCSI
devices to the Adaptec SCSI Card 29320. Before connecting
devices, be sure to review Setting Up SCSI Devices on page 3.
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
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.

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 29320 has one internal 68-pin LVD/SE
connector and two internal SE connectors to which you can
connect internal SCSI devices, as shown in the figure on page 1.
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, shown as follows.
Plug the nonterminated end of the cable(s) to one of the internal
LVD/SE connectors.
Adaptec recommends that you keep your Ultra320/160
and Ultra2 SCSI devices separate from your Ultra SCSI
devices. This allows the Ultra320/160 and Ultra2 SCSI devices
to transfer data at their maximum speed.

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.
Connect a power cable from your computer’s internal power
supply to each internal SCSI device.
Connecting Wide SCSI Devices
Connect internal Wide SCSI devices to the 68-pin internal SE
Wide SCSI connector. To do this, use a 68-pin Wide SCSI cable
like the one shown in Step 1 below. Follow these steps to connect
the devices:
Locate a 68-pin internal Wide SCSI 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.

Plug one end of the cable to the Wide SCSI connector on the
Adaptec SCSI Card 29320.
Plug the other end of the cable to a terminated Ultra/Fast Wide
SCSI device.
If you have other Ultra/Fast Wide SCSI devices, attach them to
the connectors between the two ends of the cable. Be sure these
other devices are un-terminated.
Connect a power cable from your computer’s internal power
supply to each internal device.
Connecting Internal Ultra/Fast Narrow Devices
Connect internal Ultra/Fast Narrow SCSI devicesthat have
standard 50-pin connectors to the 50-pin internal SE Narrow
SCSI connector. To do this, use a 50-pin internal Ultra Narrow
SCSI cable. Follow these steps to connect the devices:
Locate a 50-pin internal Ultra Narrow SCSI cable.
Plug one end of the cable to the 50-pin internal SE Narrow SCSI
connector on the Adaptec SCSI Card 29320.

Connecting External SCSI Devices
You can connect external Ultra320/160 and Ultra2 SCSI devices
to the 68-pin external LVD/SE SCSI connector. Each external
device will require a 68-pin 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 29320.

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.
