This Installation Guide describes how to install the Adaptec SCSI Card
2930CU. It also describes how to install and connect your internal and
external SCSI devices.
For instructions on how to install the SCSI card driver, refer to the SCSI
Card 2930CU User’s Guide on the SCSI Card 2930 CD.
Kit Contents
Your SCSI Card 2930 package includes:
■SCSI Card 2930CU adapter
■Standard 50-pin internal SCSI cable
■SCSI Card 2930 CD, containing drivers, online documentation, and
other useful tools and information
■Adaptec SCSI Card 2930CU Installation Guide
If you plan to connect more than two internal SCSI devices, or one or
more external SCSI devices, to your computer, you will need additional
cables not included in this package. Refer to the SCSI Card 2930CU User’s
Guide on the SCSI Card 2930 CD for information on obtaining cables.

Installing the SCSI Card 2930CU
To install the SCSI Card 2930CU
1Ground yourself by touching the chassis.
2Turn off the computer and disconnect the power cord.
3Open the computer cabinet, following the manufacturer’s
instructions.
4Find an unused PCI expansion slot (typically white or ivory) in the
computer. Unscrew the expansion slot cover screw and remove the
slot cover to provide an opening, as shown. Save the slot cover screw
for use in Step 7.

5Remove the SCSI Card 2930CU from its antistatic packaging.
Note: Always handle the SCSI card by its edges or metal bracket.
Do not touch the gold connector or any components on the card.
6Place the SCSI Card 2930CU in the slot and press it down firmly until
the connector fingers are fully seated.
7Secure the card bracket with the screw you removed in Step 4.
Do not close the computer cabinet or reconnect the power cord yet.
Continue with the next section, Installing Internal SCSI Devices.

Installing Internal SCSI Devices
If you are connecting only external devices, skip to Connecting External
SCSI Devices on page 8.
To install internal SCSI devices
1Ensure that each internal SCSI device has a unique SCSI ID number
between 0 and 6. Refer to the SCSI device’s documentation for
instructions on setting the SCSI ID.
Note: Avoid touching the device connector pins.
2Mount each SCSI device in an available drive bay inside your
computer. Refer to the documentation for your computer and SCSI
devices for installation instructions.
Note: If space is limited inside your computer, you may have
difficulty connecting SCSI and power supply cables to your
SCSI devices once they’re installed. Consider completing these
connections (starting with Step 3) before installing the devices.
3Connect one end of the 50-pin internal SCSI cable to the SCSI
connector on the card, as shown in the next figure. Ensure that the
connector fits snugly.
Make sure Pin 1 on the cable aligns with Pin 1 on the internal SCSI
device connector. Pin 1 is usually designated by a “1” or small
triangle.

4Connect the other end of the cable to the internal SCSI device.
5If you are installing one internal SCSI device only, you must
terminate this device, then skip to Step 8 on page 7.
Refer to your SCSI device’s documentation for termination
instructions.

7Terminate the device that is connected to the end of the cable. Refer
to the SCSI device’s documentation for instructions.
8Connect a power cable from your computer’s power supply to the
power input connector on the SCSI device, as shown. Repeat this
step for each SCSI device.

9Close the computer cabinet. Do not reconnect the power cord yet.
If you are also connecting external SCSI devices, skip to the next
section, Connecting External SCSI Devices.
If you are not connecting external SCSI devices, complete the
installation by continuing with Step 10.
10 Reconnect the power cord, then turn on the computer.
11 Install the software driver for your operating system. See Installing
Drivers on page 11 for more information.
Refer to the SCSI Card 2930CU User’s Guide on the SCSI Card 2930 CD for
useful information on SCSI, SCSI devices, and using SCSISelect.
Connecting External SCSI Devices
The SCSI Card 2930CU has one 50-pin high-density external connector.
You will need a high-quality 50-pin high-density external SCSI cable for
each external SCSI device you are connecting. External SCSI cables are
not included in the SCSI Card 2930CU kit. Refer to the SCSI Card 2930CU
User’s Guide on the SCSI Card 2930 CD for more information on cables.

To connect external SCSI devices
1 Ensure that each external SCSI device has a unique SCSI ID from 0 to 6.
For most external SCSI devices, the SCSI ID is set with a switch on the
back of the device, as shown. Refer to the SCSI device’s documentation
for instructions on setting the SCSI ID.
Note: Each device connected to your SCSI Card 2930CU (both
internal and external) must have a unique SCSI ID from 0 to 6. You
cannot use the same SCSI ID twice.

2 Connect one end of an external SCSI cable to the SCSI Card 2930CU
external SCSI connector. Secure the cable by tightening the thumb
screws on the cable connector.
Note: Avoid touching the device connector pins.
3Connect the other end of the cable to a SCSI connector on the back of
the SCSI device.
4If you are installing only one external SCSI device, terminate the
device.
Refer to your SCSI device’s
documentation for termination
instructions.
5Connect other external SCSI devices by cabling each device to the
previous one, as shown. Only terminate the SCSI device at the end of
the chain.
