RRD43 Disc Drive Installation for MicroVAX 3100 & VAX 4000

This document is the RRD43 CD-ROM Disc Drive Installation Guide for Digital Equipment Corporation's MicroVAX 3100 and VAX 4000 Model 100 Systems, published in March 1994.

The guide describes the RRD43-AA CD-ROM drive as a half-height, Small Computer Systems Interface (SCSI) device capable of reading industry-standard 600 MB discs at 1X (150 KB/s) or 2X (300 KB/s) speeds, with an average access time of 320 ms.

The document provides step-by-step instructions for installing the RRD43-EK field-installable option, covering:

1. Drive Contents: Listing components like the drive, mounting bracket, and screws.
2. SCSI ID Information: How to determine and set a unique SCSI ID for the drive using jumpers, including a table of settings and noting a "Parity" jumper for Digital vs. PC operation modes.
3. Installation Procedures: Detailed steps for preparing the specific MicroVAX 3100 (Model 30, 40, 80, 90) or VAX 4000 Model 100 systems (e.g., removing enclosure covers, specific mounting bracket attachments, removing blank bezel inserts), connecting power and SCSI cables, and physically securing the drive in the appropriate storage slot.
4. Diagnostic Support: Commands (T SCSI, T 10, T EO) to test the installed RRD43 option from the console prompt, and how to interpret successful or failed test results.
5. Drive Specifications: A comprehensive table detailing technical specifications such as capacity, form factor, transfer rates, rotational speeds, environmental conditions, and power requirements.

The guide is essential for users and technicians performing field installations of the RRD43 CD-ROM drive in compatible Digital Equipment Corporation systems.
