Verify that each internal SCSI device you are installing has a
unique SCSI ID from 0 to 6 (0 to 6 and 8 to 15 for“Wide”SCSI
devices). Refer to the device’s documentation to determine the
SCSI ID setting.
If any two SCSI devices (internal or external) you are connect-
ing to the SCSI Card 2940UW Pro share the same SCSI ID,
change the SCSI ID on one device.The SCSI Card 2940UW Pro
is preset to SCSI ID 7 and should not be changed. See the SCSI
Card 2940UW Pro User’s Reference for additional information
on SCSI IDs.
If you are installing only one internal SCSI device,terminate
that device. If you have two or more devices on each cable,ter-
minate one device on each cable; the remaining devices must
not be terminated. (The terminated device must be connected
to the end of each cable, as explained in Step 5 below.)
The termination setting usually is controlled by setting a
jumper or a switch, or by physically removing or installing a
terminator module(s).Refer to the device’s documentation
to enable or disable termination on your device. See the SCSI
Card 2940UW Pro User’s Reference for additional information
on termination.
CONNECTING INTERNAL SCSI DEVICES
STEP 1
STEP 2
Mount each internal SCSI
device in an available
drive bay inside your
computer.
Refer to your computer
and device documenta-
tion for instructions on
installing devices inside
your computer.
Internal SCSI Device Mounted in
Drive Bay Inside Your Computer
If it is difficult to reach the back of your internal SCSI
devices when they are mounted in a drive bay, you can connect the
internal SCSI devices to the SCSI cable and power supply (Steps 5-7
below) before mounting each device inside your computer.

Connect one end of the internal SCSI cable to the
SCSI Card 2940UW Pro’s internal SCSI connector.
Each cable included in this package allows you to connect up to
two internal SCSI devices. To connect more than two internal
SCSI devices to each internal connector on the SCSI Card
2940UW Pro,you will need an internal SCSI cable with enough
connectors to accommodate all of your devices. See the SCSI
Card 2940UW Pro User’s Reference for additional information
on connecting your SCSI devices and ordering cables.

STEP 8
Verify that each external SCSI device you are installing has a
unique SCSI ID from 0 to 6 (0 to 6 and 8 to 15 for“Wide”SCSI
devices). Refer to the device’s documentation to determine the
SCSI ID setting.
If any two devices (external or internal) you are connecting to
the SCSI Card 2940UW Pro share the same SCSI ID, change the
SCSI ID on one device. The SCSI Card 2940UW
Pro is preset to SCSI ID 7 and should not be
changed.
For most external SCSI devices, the
SCSI ID usually is set with a
switch on the back of the
device. See the SCSI Card

68-pin External SCSI Cable
50-pin External SCSI Cable
68-pin to 50-pin Adapter
(Adaptec Part # ACK-68P-50P-E)
Connect one end of the external SCSI cable to the SCSI Card
2940UW Pro’s external SCSI connector. Push the connectors
together until they lock in place.
For each external SCSI device you install, you need a high-
quality external SCSI cable. If you need to connect an
external SCSI device with a 50-pin cable, then you also need a
68-pin to 50-pin external converter that actively terminates the
high byte. This converter is available through Adaptec
(Part # ACK-68P-50P-E). See the SCSI Card 2940UW Pro User’s
Reference for additional information on connecting your SCSI
devices and ordering cables and adapters.
STEP 2
Connect the other end of the cable to a SCSI connector on the
back of the external SCSI device.If you are installing only one
external device, terminate the device and skip to Step 5.
Termination usually is controlled by installing or removing a
SCSI terminator. On some devices,
you use a switch or button on
the back of the device. Refer
to the device’s documenta-
tion to determine how to
enable or disable termina-
tion. See the SCSI Card
2940UW Pro User’s
Reference for additional
information on
termination.

• Is the PCI expansion slot PCI Rev. 2.0 or higher compliant and does it sup-
port Bus Mastering?
• Are all SCSI devices and the SCSI Card 2940UW Pro assigned unique SCSI
IDs? (See Step 1 in Connecting Internal SCSI Devices or Connecting
External SCSI Devices.)
• Are all SCSI devices terminated properly? (See Step 2 in Connecting
Internal SCSI Devices or Step 3 in Connecting External SCSI Devices.)
If you have problems with a specific SCSI device when other connected
SCSI devices are working correctly, please contact the manufacturer of the prob-
lem device for troubleshooting information.
NOTE
TROUBLESHOOTING CHECKLIST
If you have any problems during the installations, check the
following items first:
• Are all SCSI devices turned on?
• Are all SCSI cables and power cables properly connected?
• Is the SCSI Card 2940UW Pro firmly seated and secured in the PCI
expansion slot?
Most problems with using the SCSI Card 2940UW Pro result from errors in
preparing and connecting devices on the SCSI bus.Additional troubleshoot-
ing information is provided in the SCSI Card 2940UW Pro User’s Reference.

Some configuration options apply to a specific PCI bus slot, so if you
change any option be sure you are applying the change to the correct slot.
Check your computer documentation to determine the correct PCI bus slot.
NOTE
If your computer allows you to set up configuration options when the
computer first boots up (that is, through CMOS setup), are the follow-
ing options set up as specified?
• If there is an Interrupt Type or Interrupt Line option in the Setup
program, select Int-A or Interrupt Type = A (you may also be
required to change a motherboard jumper setting).
• If there is a Triggering Interrupt option, select Level.
• If there is an option to enable or disable bus mastering for the PCI
slots, select Enabled.
• If there is an option to enable or disable individual PCI slots, be sure
the slot in which you install the SCSI Card 2940UW Pro is Enabled.
• If your computer has a combination of ISA (or EISA) boards and PCI
boards, you may need to mark the IRQs used by ISA/EISA boards as
Used so the computer BIOS will not try to assign these IRQs to other
PCI boards.
• In some computers, the BIOS reserves a set of available IRQs for PCI
boards, and you have to assign these IRQs manually.
