If you are installing external SCSI devices only, replace

the computer chassis cover and skip to Installing External

SCSI Devices on page 4.

Installing Internal SCSI Devices

Step 1:

Install or enable terminators on the internal

SCSI device that you plan to connect to the end of the

internal cable. Then remove or disable terminators on all

other internal devices.

On most internal SCSI devices, you control termination

by setting a jumper or a switch, or by physically remov-

ing or installing a resistor module(s). Refer to the

device’s documentation to determine how to enable or

disable termination on your particular device.

Step 2:

Install and mount each internal SCSI device

inside your computer. (Refer to your computer and

device documentation for instructions.)

If you purchased your AHA-2920C as part of an Adaptec

kit, the kit includes one 50-pin internal SCSI cable that

allows you to connect up to two internal SCSI devices.

Step 3:

Plug one end of your 50-pin internal SCSI cable

into the host adapter’s internal SCSI connector. To

connect more than two internal devices, you will need to

obtain or purchase a SCSI cable with enough connectors

to accommodate all of your devices.

Make sure that the colored stripe on one side of the cable

is aligned with pin-1 of the host adapter’s connector.

Pin-1 of the connector is usually designated by a small

triangle (

), or a “1” on the connector.

Step 4:

Plug the other end of the 50-pin internal SCSI

cable into the connector on the last internal SCSI device

in the chain. (This device must be terminated.) Make sure

the colored stripe on the side of the cable is aligned with

pin-1 of the SCSI device’s connector.

Step 5:

Plug the remaining cable connectors into any

remaining internal devices. (These devices must not be

terminated.)
