VAX P.S.I. (Packetnet System Interface) Installation Procedures

This manual provides detailed instructions for installing VAX Packetnet System Interface (PSI) and VAX PSI Access, covering Native mode, Multi-host mode, Access mode, and Combination systems on VAX/VMS V5.0 with VAX PSI V4.2.

Key aspects of the installation process include:

1. Pre-installation Preparations: This involves installing the WAN Synchronous Drivers kit, gathering critical system and network configuration information (e.g., network names, DTE addresses, device parameters), and verifying sufficient disk space as per specified requirements.
2. Software Installation: Using the VMSINSTAL procedure to copy VAX PSI and/or VAX PSI Access files from distribution kits to the system disk. This stage also includes reviewing release notes and selecting optional components like X.29 support and various utilities.
3. System Configuration: Running PSI_SET_UP.COM to configure devices, define network connections to Public Switched Data Networks (PSDNs), and set up essential databases (X25-PROTOCOL, X25-SERVER, X29-SERVER). It also covers configuring PSI MAIL for sending and receiving messages.
4. Parameter Updates: Adjusting SYSGEN parameters (such as MAXBUF, NPAGEDYN, NPAGEVIR, IRPCOUNT) to ensure adequate nonpaged dynamic pool space and I/O capacity, often necessitating a system reboot.
5. System Startup: Initiating VAX PSI using STARTPSI.COM (if DECnet is active) or STARTNET.COM (to start both DECnet and VAX PSI).
6. Licensing: VAX PSI and VAX PSI Access require licensing via the VMS License Management Facility (LMF) using a Product Authorization Key (PAK).
7. System Changes: The document also outlines procedures for migrating between different VAX PSI modes (Native, Multi-host, Access, Combination) and adding new network connections or PSI systems.

The manual is intended for system managers and Digital software specialists familiar with VAX/VMS software installation, various networking concepts (LANs, WANs, DECnet-VAX, packet switching), and the VAX PSI product. It frequently references other VAX PSI documentation for in-depth information on management, programming, problem-solving, and utilities.
