NVRAM Module (PMTNV-AA) Owner's Guide

This document is the Owner's Guide for the NVRAM Module (PMTNV-AA).

It provides general information about the PMTNV-AA NVRAM (Non-Volatile Random Access Memory) module, which is a TURBOchannel module offering 1 megabyte of storage with a lithium battery for memory retention.

Key areas covered include:

• Module Description: Its purpose (nonvolatile RAM storage), compatibility with DEC OSF/1, and the limitation of using only one module per system.
• Physical Features: Explanations of the module's LED indicators (for battery connection, readiness, and replacement alerts) and a battery test push button.
• Installation Confirmation: Steps to verify proper installation by checking the system's configuration display, noting that detailed physical installation instructions are found in a separate "hardware options guide."
• Self-Tests: Instructions for running optional diagnostic tests in console mode, including specific tests for address lines, CSR read/write capability, battery function, DMA, and memory read/write transactions. It also describes a power-down data integrity test and available test scripts (thorough, quick, manufacturing).
• Battery Information: Appendix A provides specifications for the 200mAh lithium primary battery, including its estimated shelf life and operational lifespan under various system power and battery connection scenarios.
