The following FCC Notice applies to the DLT2000 drive:
FCC NOTICE : 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 residential installation. Any
changes or modifications made to this equipment may void the user’s authority to operate this
equipment.
This equipment generates, uses, and radiates 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 tuning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
4. Consult the dealer or an experienced radio/TV technician for help. The shielded
interconnect cable shipped with the unit should not be altered or modified in any way. The
unit shipped without a shielded interconnect cable must use a shielded interconnect cable.
The user may find the following booklet prepared by the Federal Communications Commission
helpful: How to Identify and Resolve Radio-TV Interference Problems. This booklet is
available from the U.S. Government Printing Office, Washington D.C., 20402. Stock No. 00400398-5.
All external I/O cables connecting to this unit need to be shielded. See the User Manual or
installation instructions for more options.
This digital apparatus does not exceed the Class B limits for radio noise emissions set out in
the radio interference regulations of the Canadian Department of Communications.
This equipment is in the 2nd Class Category (information equipment to be used in a residential
area or an adjacent area thereto) and conforms to the standards set by the Voluntary Control
Council For Interference by Data Processing Equipment and Electronic Office Machines aimed
at preventing radio interference in such residential area.
This equipment meets or exceeds requirements for safety in the U.S. (UL 1950), Canada (CSA
C22.2 N0. 950) and Europe (EN60950/IEC 950) requirements, and is certified to bear the GS
mark by TUV.
The following FCC Notice applies to DLT2500 and DLT2700 mini-library:
FCC NOTICE : This equipment has been tested and found to comply with the limits for a
Class A device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Any changes or modifications made to this
equipment may void the user’s authority to operate this equipment. Operation of this equipment
in a residential area may cause interference in which case the user at his own expense will be
required to take whatever measures may be required to correct the interference. The shielded
interconnect cable shipped with the unit should not be altered or modified in any way. The unit
shipped without a shielded cable must use a shielded interconnect cable.
Warning! This is a Class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
Achtung! Dieses ist ein G erat der Funksto rgenzwertklasse A. In Wohnbereicghen konnen bei
Betrieb dieses Gerate s Runfunkstorungen auftreten, in welchen Fallen der Benutzer fur
entsprechende GengenmaBnahmen verantwortlich ist.
Attention! Ceci est un produit de Classe A. Dans un environment do mesti que, ce pro duit
risque de creer des interferences radioelectriques, il appartiendra alors a l'utilisateur de prendre
les mesures specifiques appropriees.

differential, fast driver/receivers.
1.3 Fast Data Transfer Rate
Used for unattended backups or archiving, the DLT2000/DLT2500/DLT2700 allows
the user to back up a higher data capacity at a high speed. The
DLT2000/DLT2500/DLT2700, when operating in a non-compressed mode, has a
maximum transfer rate of 1.25 MB/s. When operating in the compressed mode, the
maximum transfer rate is 2.5 MB/s write and 3.0 MB/s read.
1.4 High-Capacity
The amount of data the user can store on a tape CompacTape III cartridge can be up to
10.0 GB native capacity or 20.0 GB compressed, depending on whether you select
compression mode. Built-in data compression increases cartridge capacity and drive
transfer rate 2 to 2.5 times. Compression can be selected on the loader or drive front
panel or fro m the host by using the SCSI MODE SELECT command.
1.5 Compaction
The compaction feature of the DLT2000 helps you to store data efficiently. A
read/write data cache of 2.0 MB allows working space for the compaction, enabling
maximum use of available tape space.
1.6 Durable Media
The CompacTape III tape media can endure 500,000 passes and has a shelf life of 30
years, which provides superior media durability and data reliability.
1.7 Compatibility
Quantum is committed to maintaining compatibility within the DLT family of tape
drives. DLT2000/DLT2500/DLT2700 tape products are the fourth generation of tape
products, started with the DLT260 and DLT600 drives.
The DLT2000/DLT2500/DLT2700 complies with the ANSI standard for SCSI-2. The
tape media format follows ECMA approved and ANSI proposed standards.

Overview and Features of the DLT2000/DLT2500/DLT2700 Product
The user can select tape density for the CompacTape III cartridge on the loader or drive
front panel or by using the SCSI MODE SELE CT command. The
DLT2000/DLT2500/DLT2700 can write 2.6, 6.0, and 10.0 GB tape formats for 100%
interchange compatibility with earlier DLT drives using the CompacTape III cartridge.
On a write from BOT, the DLT2000/DLT2500/DLT2700 reformats the CompacTape
III cartridge recorded at 2.6, 6.0, or 10.0 GB format to the new specified format using
the new specified format.
1.8 Firmware Update Capability
The DLT2000 includes Flash EEPROM technology that allows easy on-site installation
of microcode updates from tape.
1.9 Embedded Diagnostics
The DLT2000 has embedded diagnostic software that tells you when head cleaning is
required, and indicates diagnostic results, and drive operating status. The drive has
embedded data logging of errors for failure analysis.
