Adaptec PowerDomain 29160 User manual

The Adaptec SCSI Card 29160 Ultra160 SCSI controller enables
you to connect up to 15 SCSI devices—such as hard disk drives,
scanners, and CD-ROM drives—to any Intel-based computer
with 32-bit or 64-bit PCI expansion slots. You can connect newer
Ultra160 and Ultra2 SCSI devices to the two 68-pin Low Voltage
Differential/Single-Ended (LVD/SE) connectors. You can also
connect legacy SCSI devices to the 68-pin and 50-pin internal
Single-Ended (SE) connectors.
Although the Adaptec SCSI Card 29160 is a 64-bit PCI 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 29160
•Set up SCSI devices
•Connect SCSI devices
INTRODUCTION
The Adaptec SCSI Card 29160 is designed for computer
system original equipment manufacturers (OEMs). Use this
product with the original computer system designed by the
OEM; each OEM tailors their product specifications for their
specific design needs. Adaptec assumes no responsibility for
incompatibility or consequential damages if you use the
Adaptec SCSI Card 29160 in another computer system. All
product support and services are provided by the OEM.

Bus Segments on the Adaptec SCSI Card 29160
The Adaptec SCSI Card 29160 features Adaptec SpeedFlex™
technology. SpeedFlex technology ensures that you get the best
performance from your Ultra160 and Ultra2 SCSI devices by
electronically isolating the primary LVD/SE segment from the
secondary SE segment on the SCSI bus. This allows the Adaptec
SCSI Card 29160 to support newer Ultra160 and Ultra2 SCSI
devices at speeds up to 160 MBytes/sec on the primary LVD/SE
segment while at the same time supporting Ultra (legacy) devices
at speeds up to 40 MBytes/sec. on the secondary SE segment. The
following figure shows the two SCSI segments
If you attach Wide Ultra or Ultra SCSI devices to the
LVD/SE connector(s), the data transfer rate for all attached
Ultra160 and Ultra2 SCSI devices will drop to Ultra SCSI per-
formance levels. However, if you attach only Ultra160 and
Ultra2 SCSI devices to the LVD/SE connector(s), data will be
transferred at the maximum possible rate (80 MBytes/sec for
Ultra2 devices and 160 MBytes/sec for Ultra160 devices).

Discharge any static electricity build-up before handling the 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 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 expansion slot
must be compliant with PCI Rev. 2.1 or higher 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 slots. If your com-
puter is a tower model, lay it on its side to make it easier to install
the Adaptec SCSI Card 29160.
Insert the Adaptec SCSI Card 29160 into the PCI 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 29160:
•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. Refer to the Adaptec SCSI Card 29160 User’s Ref-
erence for more information on these topics.
Be careful when inserting the Adaptec SCSI Card
29160 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 29160 and each device you connect to it
must have a unique SCSI ID number ranging from 0 to 15. No
two devices can have the same number.
The Adaptec SCSI Card 29160 is preset to SCSI ID 7 and should
not be changed. If your computer will boot from a SCSI hard
disk, make sure the SCSI ID of that hard disk 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 up to 15 SCSI devices to the Adaptec SCSI Card
29160. Before connecting devices, be sure to review Setting Up
SCSI Devices on page 4.
Connecting Internal Ultra160 and Ultra2 Devices
Connect internal Ultra 160 and Ultra2 SCSI devices to the inter-
nal LVD/SE connector on the Adaptec SCSI Card 29160. To do
this, use a 68-pin internal LVD cable like the one shown in Step 1
below. Follow these steps to connect the devices:
CONNECTING SCSI DEVICES
We recommend that you keep your Ultra160 and
Ultra2 SCSI devices separate from your Ultra SCSI devices.
This allows the newer Ultra160 and Ultra2 SCSI devices to
transfer data at their maximum speed. (See Bus Segments on
the Adaptec SCSI Card 29160 on page 2.)

Locate a 68-pin internal LVD SCSI cable, which may have either
twisted wires as shown below or flat, laminated wires.
Plug the non-terminated end of the cable to the internal LVD/SE
connector.
Plug the internal Ultra2 or Ultra160 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 sup-
ply 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.
Plug one end of the cable to the Wide SCSI connector on the
Adaptec SCSI Card 29160.
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 sup-
ply to each internal device.

Connecting Internal Ultra/Fast Narrow Devices
Connect internal Ultra/Fast Narrow SCSI devices that have stan-
dard 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 29160.
Plug the other end of the cable to a terminated Ultra/Fast Narrow
SCSI device.
If you have other Ultra/Fast Narrow 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 sup-
ply to each internal device.

Connecting External SCSI Devices
Connect external Ultra2 and Ultra160 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 the external devices:
Connect one end of the external LVD SCSI cable to the external
LVD/SE connector on the Adaptec SCSI Card 29160.
Connect the other end of the external SCSI cable to a SCSI con-
nector on the back of an external SCSI device.
If you are installing only one external device, terminate the device
and skip to Step 4.
We recommend that you connect only Ultra160 and
Ultra2 SCSI devices to the external SCSI connector. If you
also attach older Ultra SCSI devices, the data transfer speed of
the Ultra160 and Ultra2 SCSI devices will drop to the speed of
the older devices. (See Bus Segments on the Adaptec SCSI
Card 29160 on page 2.)
