DEC 3000 Model 400 AXP Options Guide

This "Options Guide" for the DEC 3000 Model 400/400S AXP system, published by Digital Equipment Corporation in March 1993, is a comprehensive technical manual. It provides detailed instructions for users and service representatives on how to install, remove, and test a variety of internal hardware options.

Key internal options covered include:

• Removable-media drives (such as RRD42 compact disc, RX26 diskette, TZK10, TLZ06, and TZ30 tape drives)
• Fixed-disk drives (RZ24L, RZ25, and RZ26)
• Memory modules
• TURBOchannel option modules (including various graphics cards, network adapters, and SCSI adapters)

The guide also briefly describes and illustrates the connection of external peripherals like console terminals, dial/button boxes, headsets, modems, printers, and tablets. For each internal option, it includes installation/removal procedures, testing methods, and hardware specifications.

Crucially, the document outlines preparatory steps such as backing up files, shutting down the system, removing the cover, and using antistatic precautions. It also instructs on verifying installations using console commands like show device, show config, and show memory, and advises on troubleshooting common errors.
