SCSI Card 2906
Introduction
With SCSI Card 2906, you can connect up to seven SCSI devices to
any IBM-compatible computer with Bus Mastering PCI expansion
slots.
This installation guide provides step-by-step instructions for
■Installing the SCSI Card 2906
■Preparing the SCSI devices
■Connecting internal SCSI devices (for example, SCSI hard disk
drives)
■Connecting external SCSI devices (for example SCSI scanners,
CD-Recordable drives, or backup tape drives)
■Installing the SCSI Card 2906 software
See the SCSI Card 2906 User’s Reference included in this package for
additional information on using the SCSI Card 2906.
Before You Begin
Make sure your SCSI Card 2906 package includes the following
items:
■SCSI Card 2906
■Standard 50-pin Internal SCSI Cable
■Adaptec EZ-SCSI diskette for Windows95/98
■Adaptec EZ-SCSI diskette for Windows3.1/DOS
■SCSI Card 2906 User’s Reference
■SCSI Card 2906 Install Guide
Check your computer properties for an available Interrupt Request
(IRQ) setting. Follow these steps to find an available IRQ setting:
1
In Windows 95/98, click the Start button, point to Settings,
and then click Control Panel.
2
Double-click System.
3
In the System Properties window, open Device Manager.

4
In Device Manager, double-click Computer at the top of the
list.
5
In the Computer Properties window, click Interrupt request
(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
may have vertical or horizontal expansion slots, as shown in
the following diagram. Refer to your computer manual to
locate the PCI slots.

3
Remove the SCSI Card 2906 from its antistatic packaging.
Always handle the card by its edges.
4
Insert the SCSI Card 2906 in the slot, pressing it down firmly so
the gold fingers are seated in the slot as shown in the following
diagram. Secure the SCSI card bracket with the screw you
removed in Step 2.

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.
