(IRQ) (if it is not already selected) as shown in the following
sample screen:
■The Settings column lists the IRQs in use. IRQ settings range
between 0 and 15. If an IRQ setting is not listed under Settings
this means it is available. In the screen sample above, setting 10
is not listed and, therefore, is an available IRQ.
Note:
Do not use an IRQ below IRQ 9 for a SCSI Card 2906.
Do not allow the SCSI Card 2906 and another card to share
the same IRQ.
■If an IRQ setting is available, you may begin this installation. If
an IRQ setting is not available, you will not be able to install
this SCSI card. See the section titled Troubleshooting in Windows
95/98 in the SCSI Card 2906 User’s Reference for additional infor-
mation on IRQ settings.

Determine which SCSI devices will be connected to the computer. If
you want to connect more than two internal SCSI devices or one or
more external SCSI devices, you will need additional cables not
included in this package. These cables are described in the SCSI Card
2906 User’s Reference.
Installing the SCSI Card 2906
WARNING:
Before you start, turn OFF power to the computer
and disconnect the power cord. Then ground yourself by
touching an unpainted surface of the computer case.
1
Remove the cover from your computer, following the manu-
facturer’s instructions.
2
Find an unused PCI expansion slot (typically white or ivory) in
your computer. Unscrew the expansion slot cover screw and
remove the cover to provide an opening as shown in the fol-
lowing diagram.
Note:
If your computer is a tower model, it is easier to install
the SCSI card when the tower is laid on its side. Computers

Preparing the SCSI Devices
Setting up SCSI devices before attaching them to the SCSI card typi-
cally involves setting SCSI IDs and termination, mounting internal
SCSI devices inside your computer, and connecting power cables to
each SCSI device.
Setup varies for different kinds of SCSI devices. Always refer to the
SCSI device’s documentation for specific instructions. Below are
some guidelines for setting SCSI IDs and termination on your SCSI
devices.
Note:
If you refer to the SCSI device’s documentation for
installation instructions, be sure to return to this document
and continue with Installing the SCSI Card 2906 Software on
page 14.
Check the SCSI IDs
The SCSI Card 2906 and each SCSI device you connect to it requires
a unique SCSI ID number ranging from 0 to 7. The SCSI Card 2906
and each SCSI device must have a different ID number. The SCSI
Card 2906 is preset to ID 7 and should not be changed. The IDs for
internal SCSI devices are usually set with jumpers; external SCSI
devices are usually set with a switch on the back of the SCSI device.
Terminate the Ends of the SCSI Bus
To ensure reliable communication on the SCSI bus, the SCSI 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
disabled on SCSI devices that are connected between the ends of
each cable. See the section titled Terminating the SCSI Bus in the SCSI
Card 2906 User’s Reference.
■To install internal SCSI devices, see Connecting Internal SCSI
Devices on page 7.
■To install external SCSI devices only, replace your computer
cover and skip to Connecting External SCSI Devices on page 11.

SCSI Card 2906
Connecting Internal SCSI Devices
1
Be sure that each internal SCSI device you are installing has a
unique SCSI ID from 0 to 6. Refer to the SCSI device’s docu-
mentation to determine the SCSI ID setting.
If any two SCSI devices (internal or external) you are connect-
ing to the SCSI card have the same SCSI ID, change the SCSI ID
on one SCSI device. The SCSI Card 2906 is preset to SCSI ID 7
and should not be changed. See the SCSI Card 2906 User’s Ref-
erence for additional information on SCSI IDs.
2
If you are installing one internal SCSI device only, terminate
that SCSI device. If you have two or more internal SCSI
devices, terminate the device that will be connected at the end
of the cable.
For more information on termination, refer to the SCSI device’s
documentation or the section titled Terminating the SCSI Bus in
the SCSI Card 2906 User’s Reference.
3
Mount each internal SCSI device in an available drive bay
inside your computer as shown in the following diagram.
Refer to your computer and SCSI device documentation for
instructions on installing SCSI devices inside your computer.

Note:
If it is difficult to reach behind your internal SCSI
devices mounted in the drive bay, try connecting the inter-
nal SCSI devices to the SCSI cable and power supply (Steps
5 - 7 below) before securing each SCSI device inside your
computer.
4
Connect one end of the internal SCSI cable to the SCSI Card
2906 internal SCSI connector as shown below.
To connect more than two internal SCSI devices to the SCSI
Card 2906, you will need an internal SCSI cable with enough
connectors for all devices. See the SCSI Card 2906 User’s Refer-
ence for additional information on connecting your SCSI
devices and ordering cables.

Connecting External SCSI Devices
1
Be sure that each external SCSI device you are installing has a
unique SCSI ID from 0 to 6. Refer to the SCSI device’s docu-
mentation to determine the SCSI ID setting.
If any two SCSI devices (external or internal) you are connect-
ing to the SCSI Card 2906 have the same SCSI ID, change the
SCSI ID on one SCSI device. The SCSI Card 2906 is preset to
SCSI ID 7 and should not be changed.
For most external SCSI devices, the SCSI ID is set with a switch
on the back of the SCSI device as shown below. See the SCSI
Card 2906 User’s Reference for additional information on SCSI
IDs.
2
Connect one end of the external SCSI cable to the SCSI Card
2906 external SCSI connector as shown in the following dia-
gram. Secure the cable to the connector on the SCSI Card 2906
by tightening the thumb screws on the cable connector.

12
SCSI Card 2906
For each external SCSI device you install, you need a high-
quality external SCSI cable. See the SCSI Card 2906 User’s Refer-
ence for additional information on connecting your SCSI
devices and ordering cables.
3
Connect the other end of the cable to a SCSI connector on the
back of the external SCSI device as shown below. If you are
installing only one external SCSI device, terminate the device.
Termination usually is controlled by installing or removing a
SCSI terminator. On some SCSI devices, you use a switch or
button on the back of the SCSI device. Refer to the SCSI
device’s documentation to determine how to enable or disable
termination. See the SCSI Card 2906 User’s Reference for addi-
tional information on termination.
