DEC 4000 ENCLOSURES

This document is an Illustrated Parts Breakdown (IPB) for DEC 4000 ENCLOSURES, designed to help users identify hardware parts and their locations. It is structured around detailed figures with numeric callouts, which correspond to entries in a comprehensive parts list. To use it, a user locates an item in a figure, then finds its matching number in the parts list.

The parts list provides descriptions (indicating subassemblies with asterisks), Digital/Vendor part numbers (including revision levels), ECO cut-in information, product variation codes, and cross-references to other figures within the IPB. The document also includes a "PART NUMBER/PART DESCRIPTION INDEX" for efficient part lookup and an "ECO/REVISION HISTORY" table detailing assembly versions and printing dates. It concludes with legal information, including copyright, restricted rights, and trademark declarations for Digital Equipment Corporation products. The IPB systematically breaks down the enclosures into various assemblies like the BA640 enclosure, chassis, cardcage, frame, backplane, base, plenum, door, side panel, and bezel, listing all associated components.
