Hardware Installation; System Requirements; Installation - ATTO Technology UL4D PCI Installation And Operation Manual

Install the ATTO ExpressPCI Ultra320 Host Adapter and attach your SCSI devices to it using the
instructions below. To get the best performance from your ATTO Express Ultra320 host adapters, use
Ultra 320 SCSI devices.
CAUTION CAUTION
Remember to back up your system data
before changing or installing hardware.

System requirements

The ATTO ExpressPCI host adapter package
contains the host adapter, the ATTO ExpressPCI
CD and a warranty and registration card. If any
items are missing, contact your ATTO authorized
sales representative.
To install and use the ATTO ExpressPCI UL4D
and UL4S SCSI adapters you need:
• A computer with an available 64-bit PCI-X
expansion slot (preferred) or a standard 32- or
64-bit PCI expansion slot.
• The complete ATTO ExpressPCI SCSI host
adapter package.
To install and use the ATTO ExpressPCI UL5D
and ExpressPCI UL5D LP you will need
• A computer with an available x4 PCIe expansion
slot or larger, such as x8 or x16.
• The complete ATTO ExpressPCI SCSI host
adapter package.
CAUTION CAUTION
ATTO ExpressPCI host adapters contain
components that are sensitive to
electrostatic discharge (ESD). ESD can
cause damage to the ExpressPCI host
adapter. Please follow standard methods
to avoid ESD.

Installation

Remember to back up your system data before
changing or installing hardware.
1 Plan your SCSI device connections.
If connecting both internal and external devices
to the ATTO ExpressPCI SCSI adapter, be sure
to have the appropriate cables to connect
devices.
2 Set SCSI device termination. Devices at both
ends of the SCSI bus must be terminated.

3 Hardware installation

Devices in the middle of the bus, including the
ATTO ExpressPCI adapter, must have
termination removed or disabled. ATTO
ExpressPCI SCSI adapters select the proper
termination if left in auto termination mode.
3 Set SCSI IDs. Each device on the SCSI bus
requires a unique SCSI ID, one different from
the host adapter ID. The default setting for the
ATTO ExpressPCI adapter is 7.
If you need to change this setting, refer to the
ATTO Utilities Installation and Operation
manual. Also refer to your SCSI device
documentation to determine the current SCSI
ID and how to change it. Wide (16-bit) SCSI
devices can be assigned IDs 0 to 7 and 8 to 15,
while Narrow (8-bit) devices can only be
assigned IDs ranging from 0 to 7.
4 Review system documentation to select an
appropriate slot to install your adapter. The
combined power consumption of the expansion
slots must not exceed the limits for your
system. If you have more than one expansion
card installed, ensure power consumption is
within the limits outlined for your system.
5 Power down the computer and unplug the
computer from all power sources.
6 Open the case.
7 tall the adapter in any open PCI expansion
Ins
slot. Consult your computer's documentation if
you have questions about how to install an
expansion card in your system.
8 Connect SCSI devices by inserting a SCSI
cable to the connector on the ATTO
ExpressPCI host adapter until you hear a click.
Refer to Chapter 3.1 when selecting cables.
9 Close the computer case and power it up.
ATTO ExpressPCI host adapters come
preconfigured to operate properly in a variety of
common system setups. However, some systems
may benefit by tuning the adapter for optimal
performance. Refer to the ATTO Utilities
Installation and Operation manual for more
information on changing host adapter settings.
