FCC Statement
Warning: Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to operate the
equipment.
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
•Consult the dealer or an experienced radio TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference,
and (2) this device must accept any interference received, including interference
that may cause undesired operation.
NOTE: If the SX4055F Fibre Channel Expansion Module is used, the DPT
controller will not meet Class B limits. A DPT controller with an SX4055F module
does comply with the limits for a Class A digital device.
VCCI Statement
This is a Class B product based on the standard of the Voluntary Control
Council for Interference from Information Technology Equipment (VCCI).
If this is used near a radio or television receiver in a domestic
environment, it may cause radio interference. Install and use the

What’s In the Box?
All SmartRAID V controller kits include a controller, utility diskettes
(containing drivers and the Storage Manager software for supported
operating systems), and documentation. The documentation set consists
of this User’s Manual, a Quick Install Guide, and the Storage Manager
online help system.
NOTE SmartRAID V Ultra2 SCSI controllers include the following
additional items:
•One internal Ultra/Ultra2 4-device Wide SCSI cable.
•A multimode, Ultra2 terminator (installed on the end of the
included cable).
System Requirements
The DPT Storage Manager software and device drivers require
approximately 2MB of disk space. See Chapter 5, “Software Installation”
for information about supported operating systems.
All SmartRAID V controllers are PCI 2.2 compliant and are designed to
operate in host systems that comply with revision 2.2 of the PCI
specification.
SmartRAID V Decade and Century controllers are multifunction PCI
devices. The host system must be able to properly configure multifunction
PCI devices, where one of the devices is a bridge.
SmartRAID V Millennium controllers include a PCI bridge. The host
system must be able to properly configure PCI bridges and any devices
located behind the bridge.
Refer to the file READ.ME in the DPT install directory for more
information about computer systems and motherboards that DPT has
tested for compatibility with SmartRAID V controllers. You can also select
Help–View README Information in Storage Manager to see this
information.
