RDD40 Optical Disc Drive Owner's Manual

This Owner's Manual, published in September 1988 by Digital Equipment Corporation, provides instructions for the RRD40 Optical Disc Drive.

The RRD40 is a read-only storage device that uses 4.7-inch removable optical discs, each capable of storing 600 megabytes of data, read by a laser system (classified as a Class 1 Laser Product with associated warnings). It comes in two physical variations: a Tabletop version and a "Half-Height" version (designed to be embedded), both functionally similar. The drive supports two interfaces: Q-Bus (Tabletop only) and SCSI (both versions).

The manual details:

1. Installation: Instructions for both Half-Height (briefly, generally not customer-installable for SCSI, referring to host system documentation) and Tabletop RRD40s. This includes equipment lists, voltage selection (110V or 220V), cabling procedures for Q-Bus and SCSI (including daisy-chaining and termination for SCSI), power connection, and assigning SCSI Address ID numbers (via DIP switches) or Q-Bus unit numbers (via MicroVAX Diagnostic Monitor).
2. Operation: Explanations of the front panel indicators (POWER and ACTIVITY), and procedures for loading and unloading discs, emphasizing that discs must remain within their protective caddies and be oriented correctly. It also describes how to disassemble the caddy to clean the disc or repair/replace damaged caddy parts, stressing the importance of correct reassembly for data accessibility.
3. Testing: Guidance on testing the RRD40 Subsystem on MicroVAX host systems using the MicroVAX Diagnostic Monitor (MDM). It covers both customer-run "Verify Mode" tests and "Service Mode" testing (requiring a Maintenance Kit), outlining various functional, utility, and exerciser tests. It also explains how to interpret error reports and advises contacting Digital service for persistent failures, cautioning against unauthorized repairs to Q-Bus host systems. SCSI RRD40 testing refers to host system documentation.

Finally, an appendix outlines various Digital Repair Services offered, including On-Site, Basic, DECservice, Carry-In, DECmailer, and Per Call maintenance plans.
