HSC70/40 Storage Controllers IPB

This document is an Illustrated Parts Breakdown (IPB) for the HSC70/40 Storage Controllers. Its primary purpose is to facilitate the identification and location of specific parts within these hardware products.

The document is organized around illustrated figures that visually depict various assemblies and subassemblies of the controllers, such as the main controller units (HSC70 and HSC40), mechanical top assemblies, cabinet/shield components, power supplies, doors, and internal ducts. Each part in these figures is marked with a numeric callout.

Corresponding to each figure, detailed parts lists provide comprehensive information for every component. These lists include:

• The figure and item number (callout).
• A textual description of the item, noting if it's a subassembly.
• The DEC Part No. (Digital/Vendor part number).
• ECO Cut-In details (engineering change order and revision levels).
• A Used On Code (indicating product variations).
• Reference Figure Numbers for cross-referencing.

The IPB also contains an ECO/Revision History table (with the main HSC70 entry dated 31-AUG-91) and a comprehensive Part Number/Part Description Index to allow users to quickly find items by part number or alphabetical description, linking them back to the specific figure and item number. Boilerplate legal notices and a reader feedback form are also included.
