MicroVAX 3100 Model 30 to DEC 3000 Model 400S AXP Upgrade Instructions

This document, "MicroVAX 3100 Model 30 to DEC 3000 Model 400S AXP Upgrade Instructions," provides a step-by-step guide for performing this system upgrade.

It begins by detailing which existing options (drives, expansion boxes, memory, communication) are compatible for the upgrade and instructs users to verify all components shipped in the "System Kit" and "Accessory Kit."

The upgrade process involves disassembling the MicroVAX system by removing the unit cover, fixed disk drives, and removable-media drives. Users are then guided on checking and setting SCSI ID configurations for specific drives (RZ23L, RZ24) and installing new mounting brackets (metal support plates, rubber grommets, RX26 extensions) onto the drives, with references to other manuals for some accessory bracket installations.

Crucially, the document directs users to consult the "DEC 3000 Model 400/400S AXP Owner's Guide" and "Options Guide" for the primary installation and setup of the new DEC 3000 system and its various options, including connecting peripherals.

Finally, it outlines the completion steps: testing the new system's installation by verifying detected drives using the show device command, preparing and returning the old MicroVAX system unit, and contacting Digital service to upgrade the hardware service contract.
