Connecting Internal SCSI Devices
If you are connecting internal SCSI devices, make
sure you have an internal SCSI cable with enough
connectors to accommodate all of your devices.
1
Prepare each SCSI device for installation; config-
ure the device SCSI ID and terminators (terminate
the last internal device attached to the cable). For
instructions, see the device’s documentation as
well as SCSI Configuration Guidelines on page 2.
2
Install the SCSI device in your computer. Refer to
your computer and device documentation for
instructions.
3
Plug the connector at one end of the internal SCSI
cable into the host adapter’s internal SCSI
connector.
Make sure 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 desig-
nated by a small triangle (
▲
), or a “1” on the
connector.
4
Plug the remaining connectors on the cable into
the connectors on the backs of the devices.
Make sure the colored stripe on the cable is
aligned with pin-1 of the device’s connector.
5
Connect a DC power cable (from your com-
puter ’s power supply) to the power connector on
the SCSI device.
Connecting External SCSI Devices
If you are connecting external SCSI devices to your
host adapter, you must obtain an external SCSI cable
for each external device you install.
1
Prepare each SCSI device for installation; config-
ure the SCSI ID and attach a terminating plug into
the last external device. For instructions, see the
device’s documentation as well as SCSI Configura-
tion Guidelines on page 2.
2
Plug the connector at one end of the external SCSI
cable into the host adapter’s external SCSI
connector.
