VAXstation 3100 Cover Letter

This document is a December 1989 cover letter serving as an update and errata for the VAXstation 3100 documentation kit, applicable to various models like Model 30, 38, 40, and 48.

It provides critical information on:

• SCSI Configuration: Specifies ANSI SCSI-2 rules and Digital's more conservative recommendations, including limits on SCSI IDs (7 user-configurable), cable length (max 4 meters), and the maximum number of expansion boxes (3) and total SCSI devices (7) connected to a VAXstation 3100.
• Network Connectivity: Clarifies the switch positions for ThinWire (IN) and standard (OUT) Ethernet.
• Shutdown Procedures: Outlines the correct shutdown order (expansion box, then monitor/peripherals, then system unit) and warns against adding or removing SCSI devices while the operating system is running to prevent data loss.
• Display Monitors: Notes new monitor offerings (e.g., a 16-inch color Trinitron) and informs that the VAXstation 3100 and some new monitors automatically adjust to the correct voltage.
• Errata/Corrections to Manuals:
  • Clarifies that the "erase disk utility" erases data, rather than formats, and formatting is unnecessary for Digital hard disks.
  • Updates system specifications for the VAXstation 3100 Model 38, including automatic AC input voltage, specific input current ranges, and a maximum power consumption of 348 Watts.
  • Corrects specific text and examples related to hard disk configuration and installation within the drive plate.
