USER MANUAL STATEMENTS FOR CLASS A EQUIPMENT (INTEGRATIBLE TAPE SYSTEM)

This equipment generates, uses, and may emit radio frequency energy. The equipment has been type tesand found to comply with the limits for a Class A digital device pursuant to Part 15 of FCC rules, which ar

designed to provide reasonable protection against such radio frequency interference.

Operation of this equipment in a residential area may cause interference in which case the user at his owexpense will be required to take whatever measures may be required to correct the interference.

Any modifications to this device - unless expressly approved by the manufacturer - can void the usersauthority to operate this equipment under part 15 of the FCC rules.

Note: Additional information on the need to interconnect the device with shielded (data) cables or the nfor special devices, such as ferrite beads on cables, is required if such means of interference suppressionused in the qualification test for the device. This information will vary from device to device and needs to

obtained from the EMC group or product manager.

Warning!

This is a Class A product. In a domestic environment this product may cause radio interference in whichthe user may be required to take adequate measures.

Achtung!

Dieses ist ein Gert der Funkstrgrenzwertklasse A. In Wohnbereichen knnen bei Betrieb dieses GertesRundfunkstrungen auftreten, in welchen Fllen der Benutzer fr entsprechende Gegenmanahmenverantwortlich ist.

Warning!

This Class A digital apparatus complies with Canadian ICES-003.

Cet appareil numrique de la classe A est conforme la norme NMB-003 du Canada.

Attention!

Ceci est un produit de Classe A. Dans un environnement domestique, ce produit risque de crer desinterfrences radiolectriques, il appartiendra alors l'utilisateur de prendre les mesures spcifiques

appropries.

USER MANUAL STATEMENTS FOR CLASS A EQUIPMENT (continued)

USER MANUAL STATEMENTS FOR CLASS B EQUIPMENT (TABLETOP VERSION)

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuantto Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmfulinterference in a residential installation. Any modifications to this device - unless expressly approved bythe manufacturer - can void the users authority to operate this equipment under part 15 of the FCC rules.Operation is subject to the following two conditions: (1) this device may not cause harmful interferenceand (2) this device must accept any interference that may cause undesirable operation.

This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used inaccordance 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 doescause 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 thefollowing 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 isconnected

Consult the dealer or an experienced radio/TV technician for help.

Note: Additional information on the need to interconnect the device with shielded (data) cables or theneed for special devices, such as ferrite beads on cables, is required if such means of interference

suppression was used in the qualification test for the device. This information will vary from device todevice and needs to be obtained from the EMC group or product manager.

This Class B digital apparatus complies with Canadian ICES-003.Cet appareil numrique de la classe B est conforme la norme NMB-003 du Canada.

ABOUT THIS MANUAL

About This Manual outlines the scope and contents of this manual. It containsinformation about the intended audience, purpose of the manual, document organization, and document conventions.

AUDIENCEThis manual is written for original equipment manufacturers (OEMs) that areintegrating this Quantum DLTtape system into a host system or subsystem. Its primaryaudience is the OEM technical staff that makes tape system purchase and configurationdecisions, and system integrators that are responsible for the SCSI interface.

Additionally, the manual can be used by technically astute end-users for installation andoperation of the tape system, although that is a secondary audience.

PURPOSEThis manual describes the DLT 8000 Tape System. It is intended to provide theinformation necessary to integrate the tape system into a computer system or subsystem.

DOCUMENT ORGANIZATIONThis product manual contains five chapters, a number of appendixes of related usefulinformation, and an index. It includes an overview of the Small Computer SystemInterface (SCSI) and detailed descriptions of the messages and SCSI commands as usedby the tape system. The manual is organized as follows:

Chapter 1 General Description and Specifications

This chapter contains a brief description of and specifications for thesystem.

Chapter 2 Configuring, Installing, and Operating the Tape System

This chapter contains information on system hardware and systeminterfaces.

1.3.4 Reliability (Projected)Mean time between failures (MTBF) for the tape system is projected to be 250,000 hours

at 100% duty cycle, not including heads; 300,000 hours at 20% duty cycle, not includingheads. Life of recording heads is 30,000 hours, minimum; 50,000 hours, average.

Media durability is projected to be 1,000,000 passes of the tape medium across theread/write heads (15,000 uses). One tape pass is defined as any point on the tapepassing the head in either direction.

Quantum Corporation does not warrant that predicted MTBF is representative of anyparticular unit installed for customer use. Actual figures vary from unit to unit.
