VAXstation 3520/3540 Addendum

This document is an addendum to the VAXstation 3520/3540 Maintenance Guide, focusing on the RZ56 disk drive and MS60-CA memory module options.

It provides comprehensive information for these components, including:

• Description: Detailing their specifications and capabilities. The MS60-CA is a double-sided 32 MB memory module with error correction, allowing up to 128 MB total memory, but notably lacks battery backup (data is lost on power loss). The RZ56 is a full-height 665 MB SCSI fixed-disk drive.
• Installation: Step-by-step instructions for physical installation, including setting up drive shock mounts, mounting brackets, and configuring SCSI ID addresses. It emphasizes pre-installation checks like software backup and system shutdown.
• Troubleshooting: Guidance on using power-up self-tests and system exerciser diagnostics to identify and resolve issues with both the memory module and disk drive.
• Removal and Replacement: Procedures for safely removing and replacing both the MS60-CA memory module and the RZ56 disk drive, as well as its electronic module, with a strong emphasis on antistatic procedures.
