InfoServer 150

This document is a detailed System Specification for the InfoServer 150 and InfoServer 150VXT Systems from Digital Equipment Corporation.

It describes these systems as high-performance logical block servers built upon the VAXServer 3100 Model 10E hardware. Their primary function is to provide client access to shared storage via Ethernet using LAD/LAST protocol, supporting various operating systems like VMS, Ultrix, MSDOS, MAC, and OS2 for applications such as software distribution, boot serving, and X-terminal support. The InfoServer 150VXT is a variant primarily distinguished by its use of an RZ24 SCSI disk instead of an RZ23L.

The specification comprehensively covers:

• Functional Overview: Detailing the CPU (CVax), memory, ROM, Ethernet, serial interfaces, and supported SCSI storage devices.
• Configurations: Outlining saleable hardware configurations, internal and external storage options, SCSI ID assignments, and cabling.
• Physical Specifications: Including enclosure dimensions, external switches and LEDs, and detailed environmental requirements (temperature, humidity, shock, vibration, acoustics).
• Connectors and Cabling: Providing information on external and internal connection points and internal cables.
• Power Supply and System Cooling: Specifying power requirements and the cooling system.
• Reliability and Serviceability: Presenting Mean Time Between Failures (MTBF) estimates, identifying field-replaceable units (FRUs), and outlining maintenance and diagnostic procedures.
• Testing and Product Evaluation: Listing the Digital hardware design standards and external regulations/standards (e.g., EMC, safety) that the systems comply with.

Appendices offer in-depth specification tables for physical, environmental, power, and EMC characteristics, as well as connector pinouts and reference documents.
