Illustrated Parts Breakdown 660QS Pedestal System

This document is an Illustrated Parts Breakdown (IPB) for the Digital Equipment Corporation 660QS Pedestal System, identified as EK-660QS-IP-001.

Purpose and Content: Its primary purpose is to identify and list all assemblies and their individual components for the 660QS Pedestal System. It is structured according to engineering drawing nomenclature. The document includes detailed parts lists for various sub-assemblies, such as:

• BA213 Unit Assemblies (120V & 240V)
• H3602 Bulkhead Assemblies (including MicroVAX CPU and 16MB RAM modules)
• Base Assembly
• Enclosure Assembly (Shell)
• Front Panel Assembly
• OCP Assembly
• Various cables, power cords (including international versions), screws, fasteners, brackets, and labels.
• Accessory kits containing items like screwdrivers, labels, and connectors.

How to Use the IPB (Organizational Principles):

• Indented Parts List: Parts are listed with asterisks (*) indicating their subordination to higher-level assemblies. A single asterisk means the item is part of the major assembly, while double asterisks (**) denote items subordinate to a single-asterisk item. This system aids in identifying the next higher assembly and alternative parts.

• Column Definitions:

  • Figure and Item: Links parts to their corresponding illustrations (though illustrations are not included in this text-only excerpt).
  • Description: Provides the name of the part and pertinent specifications.
  • DEC Part No.: The Digital part ordering number (may be blank if not assigned).
  • ECO Cut-In: Indicates the ECO (Engineering Change Order) level at which the IPB was initially prepared or modified.
  • Used On Code: Letters correspond to variation codes (e.g., specific voltage configurations or "Rack Kit" versions). A blank indicates the part is used on all variations.
  • Ref Fig No.: A cross-reference to other illustrations, showing either the next higher assembly or a detailed breakdown.

• FRU Level Parts: A symbol (not displayed in text, but indicated as "☐") denotes Field Replaceable Unit (FRU) level parts.

• Indexes: The document includes comprehensive Part Number/Description Indexes, allowing users to find parts both numerically by part number and alphabetically by description, referenced by figure and item numbers.
