DEC Network Integration Server 600

This document, "DEC Network Integration Server 600 Hardware Information for Digital Services" (Order Number: EK-A0571-MG.001), is a manual intended for Digital Services engineers.

Its primary purpose is to provide hardware information for the DEC Network Integration Server 600 (DECNIS 600), serving as a reference for problem-solving and testing. It is meant to supplement other DECNIS 600 installation and service manuals.

The manual covers key hardware components and functionalities, including:

• Power Module Information: Details on outputs, states (e.g., overvoltage, overcurrent indicators), test points, remote sensing, and voltage settings.
• Thermal Protection: Description of ambient air temperature sensors and switches, and how the system's fans adjust or trigger shutdown based on temperature.
• Backplane Support: Information on the DECNIS 600 bus topology (based on Futurebus+ Profile B, noting both compliance and non-compliance aspects), system bus connectors, and central arbitration.
• System Testing and Card Information: Explanations of system self-tests (for processor, memory, and Network Interface Cards), various loopback testing procedures, installation torques, and card identification conventions.

Additionally, the document includes appendices listing recommended spares and Field Replaceable Units (FRUs) for the DECNIS 600. It was first printed in April 1992.
