VAX 4000 Model 200 (BA430) Operation Manual

This document is an operation manual published by Digital Equipment Corporation (DEC) in the early 1990s (1990-1991) for the VAX 4000 Model 200 (BA430) timesharing and VAXserver 4000 Model 200 systems, which run on VMS or VAXELN operating systems.

The manual provides a comprehensive guide to:

• An overview of the system, detailing its physical components (enclosure, mass storage shelf, card cage, CPU, memory, power supply, fans) and their functions, as well as various optional components like mass storage devices, communication controllers, real-time controllers, and printer interfaces, including explanations of dual-host configurations.
• Operating the base system, covering procedures for turning it on, booting (autobooting or from console mode), general usage, halting, restarting, and turning it off, along with instructions for recovering from over-temperature conditions.
• Operating system options, with detailed instructions for using various mass storage devices (RF-series Integrated Storage Elements, TF85, TK70, and TLZ04 tape drives, optical disks, compact disc drives), communication controllers (asynchronous, synchronous, network), real-time controllers, and printer options. This includes specific steps for handling media like tape cartridges (labeling, write-protecting, inserting, removing, cleaning).
• Appendices that provide information on related documentation, programming parameters for DSSI (Digital Storage Systems Interconnect) devices from console mode, backup and restore procedures for the system disk, and methods for removing unwanted VMS files using utilities like VMSTAILOR.
