EMI/RFI Compliance

United States – FCC

WARNING: This equipment has been tested and found to comply with the limits for a Class A 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:

• Re-orient 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.

You 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, DC 20402, Stock No. 004-000-00354-04.

Canada – Department of Communications

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus as set out in the interference-causing equipment standard entitled "Digital Apparatus", ICES-003 of the Department of Communications.

Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux appareils numériques de Class B prescriptes dans la norme sur le matériel brouilleur: "Appareils Numériques", NMB-003 édictée par le ministre des Communications.

Shielded Cables

Shielded data cables are required in order to meet FCC emissions limits. The ADIC data cable meets this requirement. If you need a replacement cable, be sure to use an ADIC-approved shielded cable (to assure acceptability to FCC requirements).

Introduction

This Chapter. . .

p provides a physical description of the switches, indicators and connectors on

the rear panel of the T5 Enclosure.

Chapter

Equipment Description

The Tape Array (T5) Rackmount Enclosure can house from one to five Quantum® DLT7000 or DLT8000 SCSI tape drives in a well-integrated package for use in rackmount applications. Included on the rear panel of the T5, 10 HD68 SCSI connectors allow separate SCSI bus connections to each drive. Five drive SCSI ID selection switches are also included on the rear panel.

The DLT tape drives are mounted in easily removed carriers, which slide into the front of the T5 chassis and are retained with captive screws. The carriers contain SCSI and power connectors which dock with mating connectors mounted inside the T5 chassis and provide all power and data connections between the drives and the T5. The T5 Enclosure features a snap on/off front bezel, which can be easily snapped off for drive carrier removal, and allows access to the media cartridges when in place.

Dual, redundant hot-swappable 300-watt power supplies provide all necessary operating voltages for the DLT drives. Two cooling fans mounted on the T5 rear panel, and a self-contained cooling fan in each of the power supplies provide drive cooling.

Introduction 3

Power Supplies

Two redundant hot-swappable 300-watt power supplies provide operating voltages for the DLT tape drives installed in the T5 Enclosure. The two supplies operate in parallel using proprietary power control and sharing modules. Each supply plugs into the rear of the T5 and can be removed or replaced while the other supply keeps the system fully operational. There is a normally green indicator on the T5 rear panel, at the top of each power supply module, which extinguishes whenever the associated power supply fails, is turned off, or is removed from the chassis.
