Illustrated Parts Breakdown TK50-D/R Tape Drive Subsystem

This document is an Illustrated Parts Breakdown (IPB) for the Digital Equipment Corporation's TK50-D/R Tape Drive Subsystem, designed to aid in part identification for maintenance and replacement. It outlines its structure, beginning with a Major Assembly Locator that provides an overview of main components. Detailed Indented Parts Lists use an asterisk system to show part subordination, helping users find specific parts, identify next higher assemblies, and locate alternative selections.

The IPB explains its column fields (e.g., Figure & Item, Description, DEC Part No., ECO Cut-In, Used On Code, Ref Fig No.) and special symbols for attaching hardware, non-field repairable items, and accessories. The document includes a Revision History and references any other required IPB manuals.

Key assemblies and components detailed with corresponding figures and part descriptions include:

• The overall TK50 Tape Drive Subsystem (available in Desk Top and Rack Mount configurations), including I/O cables, power cords, and tape cartridges.
• Specific TK50-D and TK50-R Unit Assemblies, detailing chassis, bezels, logos, bumpers, and various internal labels.
• The TK Chassis Assembly, which breaks down into power supplies, switches, circuit breakers, cable assemblies, fan assembly, harnesses, and drive components.
• A Rack Mount Kit for mounting the subsystem.
• The Power Supply Assembly.
• The A.C. Harness Assembly, including filters, terminals, and connectors.

The document concludes with comprehensive lists of parts, sorted both by part number and by description, to facilitate quick lookup.
