Step 6: Make sure that all SCSI devices have unique SCSI ID's from 0 to 6. (Refer to your device documentation for SCSI ID settings and instructions on manually changing the default settings.) 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 removing or installing a resistor module(s). Refer to the device's documentation to determine how to enable or disable termination on your particular device. Pin-1 of the connector is usually designated by a small triangle (v), or a "1" on the connector.

If you purchased your AHA-2930B 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.

To connect more than two internal devices, use a SCSI cable with enough connectors to accommodate all of your devices.

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-2930B 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, use 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 one of the connectors 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.)
