• Detailed Part Information: Each listed part includes a description, DEC part number (or vendor part number for non-DEC stocked items), and relevant specifications.
• Engineering Change Order (ECO) Data: Specifies the ECO level at which parts were modified or added, crucial for compatibility.
• "Used On" Codes: Indicate which specific product variations (e.g., 50 Hz vs. 60 Hz, single vs. dual port) a part is used with.
• Illustrations: Exploded views of assemblies and sub-assemblies, with numbered items corresponding to the parts lists.
• Symbol Usage: Explanations for symbols denoting attaching hardware (@) and parts that are "Not Field Repairable" (NFR).
